PART III CLASSIFICATION OF PRIVATE WATER SUPPLIES

6 Classification and level of supplies
1 A monitoring local authority shall classify all private water supplies used or to be used in its area as a Type A or a Type B supply.
2 For the purposes of classifying a private water supply under paragraph (1), a monitoring local authority shall estimate the average volume of water provided by that supply in relation to the current year rather than by reference to the year prior to it.
3 Where a private water supply is classified a Type A supply, its level shall be determined in accordance with the following Table, by reference to the maximum average daily volume of water provided during any period of maximum supply for human consumption purposes by such supplies.

TABLE
Level	Maximum average daily volume of water supplied for human consumption purposes in m3/day
1	≤ 100
2	> 100 – ≤ 1,000
3	> 1,000
4 A monitoring local authority shall at least once in each year, review and update the classification of, and the level of, private water supplies serving premises in its area.

PART IV WHOLESOMENESS

7 Wholesomeness: Private Water Supplies
1 Water supplied to any premises from a private water supply for human consumption purposes shall be regarded as wholesome for the purposes of Part VIA of the 1980 Act, as it applies to the supply of water for those purposes, if—
(a) in respect of a Type A supply, the requirements of paragraph (2) are satisfied; or
(b) in respect of a Type B supply, the requirements of paragraph (3) are satisfied.
2 The requirements of this paragraph are—
(a) that the water does not contain—
(i) any micro–organism (other than a parameter) or parasite; or
(ii) any substance (other than a parameter),
at a concentration or value which would constitute a potential danger to human health;
(b) that the water does not contain any substance (whether or not a parameter) at a concentration or value which, in conjunction with any other substance it contains (whether or not a parameter), would constitute a potential danger to human health;
(c) that the water does not contain concentrations or values of the parameters listed in the second column of Tables A and B in Schedule 1 in excess of or, as the case may be, less than the prescribed concentration or values; and
(d) that the water satisfies the formula [nitrate]/50 + [nitrite]/3 ≤ 1, where the square brackets signify the concentrations in mg/l for nitrate (NO3) and nitrite (NO2).
3 The requirements of this paragraph are—
(a) that the water does not contain–
(i) any micro-organism (other than a parameter) or parasite; or
(ii) any substance (other than a parameter),
at a concentration or value which would constitute a potential danger to human health;
(b) that the water does not contain any substance (whether or not a parameter) at a concentration or value which, in conjunction with any other substance it contains (whether or not a parameter), would constitute a potential danger to human health; and
(c) that the water does not contain concentrations or values of the parameters listed in the second column of Table D in Schedule 1 in excess of or, as the case may be, less than the prescribed concentration or values.
4 The point at which the requirements of paragraph (2) are to be complied with is—
(a) in the case of water supplied from a tanker or an intermittent short term supply, the point at which the water emerges from the tanker or the supply;
(b) in the case of water supplied for use in a food production undertaking, the point where the water is used in that undertaking;
(c) in the case of water supplied from a distribution network, at the point, within premises or an establishment, at which it emerges from the tap or taps that are normally used for human consumption purposes; and
(d) in any other case, the point which, in the reasonable opinion of the monitoring local authority, is representative of the quality of water consumed or available for consumption throughout the year and which would otherwise be available at any of the points of compliance referred to at sub-paragraphs (a) to (c).
5 The point at which the requirements of paragraph (3) are to be complied with are those specified in sub-paragraphs (a), (c) and (d) of paragraph (4).

PART VI TYPE A SUPPLIES: RISK ASSESSMENTS, INVESTIGATIONS AND REMEDIAL ACTION

16 Type A Supplies: Risk Assessments
1 Subject to paragraph (2), a monitoring local authority shall carry out an assessment (“risk assessment”) of the potential health risks associated with all Type A supplies in their area taking into account the matters specified in Schedule 4, in order to establish whether such supplies satisfy the requirements of Part IV.
2 A monitoring local authority shall carry out a risk assessment—
(a) where the supply is a new supply and is to be used for the first time, or for the first time after being out of use for a period of 12 months or more, within 6 months of that supply being classified a Type A supply in accordance with Part III; or
(b) where the monitoring local authority considers, whether as a result of monitoring that supply in accordance with Part VII of these Regulations or otherwise, that the supply is no longer wholesome, as soon as reasonably practicable.
3 A monitoring local authority shall use the information obtained as a result of carrying out a risk assessment under paragraphs (1) and (2) to inform any remedial action as may be required under regulations 17 and 18.
4 At the same time as a monitoring local authority reviews and updates the classification of a Type A supply in accordance with Part III, it shall review and update the terms of the risk assessment, carried out under this regulation.

17 Investigations: Schedule 1 microbiological and chemical parameters
1 Subject to paragraph (3), where a monitoring local authority considers a Type A supply fails, or is likely to fail, to satisfy a requirement of regulation 7(2) that authority shall immediately take such steps as are considered necessary to identify the following matters—
(a) the cause and extent of the failure, or as the case may be, the apprehended failure;
(b) the microbiological and chemical parameters listed in Tables A and B in Schedule 1 in respect of which the prescribed concentration or value has not been, or is unlikely to be, achieved; and
(c) in relation to each parameter so identified, whether the failure, or apprehended failure, to achieve the prescribed concentration or value is attributable to—
(i) the domestic distribution system;
(ii) the maintenance of that system; or
(iii) neither of those matters.

18 Investigations: Schedule 1 indicator parameters
1 Where a monitoring local authority considers a Type A supply does not meet the specifications for indicator parameters set out in Table C in Schedule 1, it shall immediately take such steps as are necessary to identify–
(a) the indicator parameters in respect of which the specifications are not met;
(b) the reason why the specifications are not met; and
(c) if the specification for the coliform bacteria or colony count parameter (items 4 and 5 in Table C in Schedule 1) is not met, whether the inability to meet that specification is attributable to–

PART VII TYPE A SUPPLIES: MONITORING

19 Check monitoring – interpretation
In this Part, “check monitoring” means monitoring a Type A supply for the purpose of obtaining representative information at regular intervals–
(a) as to the organoleptic and microbiological quality of water; and
(b) where relevant, as to the effectiveness of drinking water treatment (particularly of disinfection),
for the purpose of determining—
(i) as regards the parameters listed in Tables A and B in Schedule 1, whether water supplied for human consumption purposes satisfies the provisions of Part IV or, if a departure has been authorised under Part V in relation to that supply, those provisions as read with the terms of that departure; and
(ii) as regards indicator parameters listed in Table C in Schedule 1, whether water supplied for human consumption purposes meets the specifications for those parameters.

20 Audit monitoring - interpretation
1 In this Part, “audit monitoring” means monitoring a Type A supply for the purpose of obtaining representative information at regular intervals from which it may be established—
(a) as regards the parameters listed in Tables A and B in Schedule 1, whether water supplied for human consumption purposes satisfies the provisions of Part IV or, if a departure has been authorised under Part V in relation to that supply, those provisions as read with the terms of that departure; and
(b) as regards indicator parameters listed in Table C in Schedule 1, whether water supplied for human consumption purposes meets the specification for those parameters.

21 Monitoring duties and powers
1 Subject to regulation 26, for the purpose of determining whether a Type A supply satisfies the provisions of Part IV or, if a departure has been authorised under Part V in relation to a Type A supply, those provisions as read with the terms of that authorisation, a monitoring local authority shall take or cause to be taken, and analyse or cause to be analysed, from any Type A supply located within its area, not less than the number of samples of water specified in, or in accordance with, the provisions of this Part.
2 Except in a case to which paragraph (3) applies, the parameters listed in Tables A to C in Schedule 1 shall be subject—
(a) as regards a parameter listed in column (2) of Table A in Schedule 2, to check monitoring; and
(b) as regards a parameter listed in column (2) of Table B in Schedule 2, to audit monitoring.
3 Where the distribution of water—
(a) is by tanker; or
(b) is, or is likely to be, an intermittent short term supply,
samples of water from each tanker or intermittent short term supply from which water is distributed shall be taken 48 hours after the commencement of the distribution from that tanker or supply and every 48 hours thereafter until the distribution is discontinued.

22 Monitoring: general provision
1 Samples from a Type A supply shall be taken such that they are representative of the quality of water intended for human consumption purposes throughout the year and, in a case where a Type A supply serves a number of premises, from such premises selected at random unless, by notice in writing to a monitoring local authority (whether or not on the application of that authority), the Scottish Ministers otherwise direct.
2 Samples are to be taken at the point of compliance determined in accordance with regulation 7(4)(a) to (d).
3 Where a monitoring local authority is required in accordance with Schedule 2 to take more than one sample within a specified period, the samples shall be taken so that they are representative of the quality of water intended for human consumption purposes throughout that period.
4 A monitoring local authority shall take and analyse a sample of water from every Type A supply to which regulations 19 and 20 apply, for the parameters referred to in Schedule 1, using the methodology specified in Schedule 5 as soon as it has been classified as a Type A supply under Part III.
5 A monitoring local authority shall as soon as reasonably practicable and, in any event, within 28 days of being requested to do so by a relevant person, take and analyse a sample of water from a Type A supply which is representative of the quality of water intended for human consumption purposes throughout the year for compliance with the prescribed concentration or value or state for the parameters specified in regulation 7(2).
6 Without prejudice to the monitoring obligations in this Part, a monitoring local authority shall have power to take and analyse a sample from a Type A supply in order to—
(a) confirm or clarify the results of the analysis of a previous sample;
(b) ascertain the effectiveness of remedial action taken in relation to the supply (whether or not such action was taken following service of a notice under section 76G of the 1980 Act).
Section 76G was added by the Water Act 1989, Schedule 22, paragraph 1.

23 Numbers of samples: Type A supplies
1 Subject to paragraph (2) and regulations 21 and 22, in each year a monitoring local authority shall take, or cause to be taken the standard number of samples of water as regards residual disinfectant and each parameter listed in column (2) of Tables A and B in Schedule 2, and shall analyse the samples for compliance with the prescribed concentrations or values or states given in Schedule 1 for those parameters.
2 Subject to paragraphs (4) and (5), where in respect of a parameter subject to check monitoring—
(a) a monitoring local authority is of the opinion that the quality of water provided by a Type A supply is unlikely to deteriorate;
(b) in each of two successive years the requirement mentioned in paragraph (3) is satisfied in relation to a parameter listed in Table A in Schedule 2; and
(c) the monitoring local authority considers the concentration or value in respect of that parameter is unlikely to increase or, in the case of hydrogen ion (item 9 in Table A in Schedule 2), decrease to any significant extent in the following year,
the number of samples to be taken in that year in respect of that parameter may be the reduced number.
3 The requirement referred to in paragraph (2)(b) is that an analysis of each sample taken in relation to the parameter in question has shown no significant variation and has established—
(a) if the parameter is colony counts, no abnormal change;
(b) if the parameter in question is hydrogen ion, a pH value that is not less than 6.5 and not more than 9.5; and
(c) in any other case, a concentration or value or state given in Schedule 1 that is constant and significantly better than the prescribed concentration or value or state for that parameter.
4 Paragraph (2)(b) shall apply in the period from 3rd July 2006 to 2nd July 2008, so that the reduced number of samples may be taken in that period in relation to a parameter if—
(a) it would have been permissible if these Regulations had been in force throughout the period of at least two years mentioned in that paragraph; or
(b) the monitoring local authority did not sample as frequently as required by paragraph (1) during the period from 3rd July 2004 to 2nd July 2006 (“the relevant period”) before these Regulations came into force but an assessment of the samples actually taken during that period, whether or not for the purpose of the 1992 Regulations, justify the reduction.
5 Except in a case where the provisions of paragraph (6) apply, in the period from 3rd July 2006 to 31st December 2006 the number of samples taken shall be—
(a) not less than one half of the standard number of samples, which number shall be rounded up, if necessary, to the nearest whole number; or
(b) where paragraph (2) applies, not less than one half of the reduced number of samples, which number shall be rounded up, if necessary, to the nearest whole number.
6 Where, in the period 3rd July 2006 to 31st December 2006, the number of samples to be taken by virtue of paragraph (5) in relation to a parameter is 1, the monitoring local authority need not sample that parameter if a sample has been taken by that authority in respect of that supply in the period 1st January 2006 to 2nd July 2006, whether or not for the purposes of the 1992 Regulations.
7 Where the analysis of the reduced number of samples taken by a monitoring local authority has established in respect of any parameter listed in Tables A and B in Schedule 2 that the prescribed specification for that parameter or, as the case may be, the relaxed specification for that parameter or, as the case may be, the relaxed specification therefor specified in an authorisation granted under Part V has been contravened, the monitoring local authority shall revert to carrying out—
(a) the number of samples proportionate to the remainder of that year in respect of that parameter; and where the result is not a whole number, that proportion rounded up to the nearest whole number; and
(b) for subsequent years, the standard number of samples.
8 Samples required to be taken by this regulation shall be taken so that they are representative of the quality of water intended for human consumption purposes throughout the year.
9 In this regulation, “the standard number” means, in relation to each parameter listed in column (2) of Tables A and B in Schedule 2, the relevant number shown for each parameter in those Tables in the columns for levels 1 to 3 respectively; and “the reduced number” means, in relation to each parameter listed in column (2) of Table A of that Schedule, the relevant number shown for each parameter in brackets in the columns for those levels.

24 Monitoring: total indicative dose and tritium
1 Where the Scottish Ministers determine that either of the conditions specified in paragraph (2) is satisfied in respect of any area within the area of a monitoring local authority, they shall by notice in writing to that authority—
(a) specify that area;
(b) specify which condition or conditions in paragraph (2) is or, as the case may be, are satisfied; and
(c) confirm that any Type A supply in that area need not be monitored in respect of the parameter to which the relevant condition relates.
2 The conditions specified in this paragraph are that Type A supplies in the area specified in the notice under paragraph (1) would—
(a) give rise to a calculated total indicative dose in respect of radioactivity that is well below the value specified in column (3) of Table C in Schedule 1; or
(b) as the case may be, contain a level of tritium that is well below the concentration specified in column (3) of Table C in Schedule 1.
3 Where the Scottish Ministers determine that a condition in paragraph (2) specified in a notice under paragraph (1) is no longer satisfied, they shall, by notice in writing, revoke any notice given under paragraph (1) to the extent it applies in respect of that condition.
4 Where a notice under paragraph (1) has been given to a monitoring local authority, and until such time as that notice is revoked, the monitoring local authority need not monitor any Type A supply in the area to which the notice relates in respect of a parameter to which the condition or conditions, as the case may be, in the notice applies.

25 Additional monitoring
1 This regulation applies to every Type A supply sampled by a monitoring local authority in accordance with this Part.
2 A monitoring local authority shall sample every supply in its area in respect of any property, element, micro-organism, parasite or substance which fulfils the conditions specified in paragraph (3).
3 The conditions specified in this paragraph are that—
(a) the supply may have or contain a property, element, micro-organism, parasite or substance not listed in Schedule 1; and
(b) the monitoring local authority considers that the concentration, amount or number of the property, element, micro-organism, parasite or substance may be such that it may (whether alone or in combination with a parameter or any other property, element, micro-organism, parasite or substance) cause the supply to fail to satisfy the provisions of Part IV or, if a departure has been authorised under Part V in relation to that supply, those provisions as read with the terms of that departure.
4 A monitoring local authority shall cause to be taken such samples at such frequency as it considers appropriate having regard to any anticipated risk of danger to human health, and which are representative of the quality of water intended for human consumption purposes throughout the year.

26 Decision on audit monitoring
1 Where a monitoring local authority has completed an investigation in accordance with Schedule 3 and is satisfied, taking into account the matters specified in Schedule 4, that one or more parameters referred to in column 2 of the Table in Schedule 3 is, or are, not likely to be present in a Type A supply in its area in concentrations which could lead to the risk of a breach of the prescribed specification in respect of such parameter or parameters as specified in Tables B and C in Schedule 1, it may decide not to monitor that parameter or those parameters in respect of that supply.
2 Before making a decision under paragraph (1), the monitoring local authority shall notify—
(a) the relevant person and any responsible person in relation to the supply;
(b) the Health Board in whose area the supply is located; and
(c) any neighbouring monitoring local authority which may have an interest in the supply.
3 The notification under paragraph (2) shall include the following details concerning the particular Type A supply—
(a) the average volume of water provided by the supply and the number of persons served by it;
(b) the parameter or parameters to which the decision relates and the results of the investigations undertaken in accordance with Schedule 3;
(c) the period during which the decision will have effect (which, subject to paragraph (6), shall be such period as the monitoring local authority considers reasonable);
(d) the period (which shall be not less than 28 days) in which representations may be made to the monitoring local authority in respect of the decision; and
(e) such other information which the monitoring local authority considers necessary.
4 A monitoring local authority shall not implement the decision until after the expiry of the period for making representations specified in any notification under paragraph (2), and after considering any representations made in response to such a notification.
5 As soon as reasonably practicable after implementing any decision, the monitoring local authority shall notify the persons specified in paragraph (2) of—
(a) the parameter or parameters listed in column 2 of the Table in Schedule 3 which the authority considers is, or are, not likely to be present in the supply in concentrations which could lead to the risk of a breach of the prescribed specification in respect of such parameter or parameters as specified in Tables B and C in Schedule 1;
(b) the conditions specified in column 4 of the Table in Schedule 3 which, the authority considers are satisfied, and a statement of the reasons for this;
(c) in respect of each parameter, the period during which the decision will have effect; and

7 A monitoring local authority shall notify the persons specified in paragraph (2) about any decision to modify or revoke any decision made under this regulation.
8 Where a decision has been revoked under paragraph (6), a monitoring local authority shall not make a further decision under this regulation in respect of that parameter or those parameters before the expiry of a period of 2 years from the date on which the revocation takes effect.

PART VIII TYPE B SUPPLIES: RISK ASSESSMENTS, INVESTIGATIONS AND MONITORING

27 Type B Supplies: Risk Assessments
1 A monitoring local authority shall, in respect of a Type B supply, provide such advice and assistance to a relevant person as will enable that person to undertake an assessment (“risk assessment”) of the potential risks to human health arising from their supply.
2 A monitoring local authority may carry out a risk assessment (whether or not on the request of a relevant person or consumer), taking into account the matters specified in Schedule 4, of the potential health risks associated with any Type B supply in their area.

28 Investigations: Table D of Schedule 1 microbiological and chemical parameters
1 Where a monitoring local authority has reason to believe that a Type B supply fails, or is likely to fail, to satisfy a requirement of regulation 7(3), that authority may take such steps as it considers necessary to identify the following matters—
(a) the cause and extent of the failure, or as the case may be, the apprehended failure;
(b) the microbiological and chemical parameters listed in Table D of Schedule 1 in respect of which the prescribed specification has not been, or is unlikely to be, achieved; and
(c) in relation to each parameter so identified, whether the failure, or apprehended failure, to achieve the prescribed specification is attributable to—
(i) the domestic distribution system;
(ii) the maintenance of that system; or
(iii) neither of those matters.
2 As soon as reasonably practicable after the matters specified in paragraph (1) have been identified, the monitoring local authority shall notify the relevant person and the appropriate local authority of those matters and of the steps that the authority considers it is necessary or desirable to take in the interests of health.
3 As soon as reasonably practicable after the relevant person receives notification given under paragraph (2), that person shall notify in writing every consumer, if any, of that supply likely to be affected by the matters specified in paragraph (1) of the cause and effect of the failure or, as the case may be, the apprehended failure, and shall provide to those consumers, details of the steps (if any) specified in accordance with paragraph (2).

29 Monitoring duties and powers
1 For the purpose of determining whether a Type B supply satisfies the provisions of regulation 7(3), a monitoring local authority may take or cause to be taken, and analyse, or cause to be analysed, from any Type B supply located within its area such number of samples, if any, of water which the authority considers is necessary to establish whether the supply is wholesome.
2 Samples from a Type B supply or from premises served by such a supply, shall be taken so that they are representative of the quality of water intended for human consumption purposes throughout the year and, in a case where a Type B supply serves a number of premises, from such premises selected at random as will ensure, insofar as is reasonably practicable, that their analysis will produce data which is representative of the quality of water so sampled.
3 Samples are to be taken at the point of compliance determined in accordance with regulation 7(5).
4 A monitoring local authority may at any time take and analyse a sample of water from any Type B supply (whether or not on the request of a relevant person or a consumer served by such a supply) for the parameters referred to in Table C of Schedule 2 to these Regulations, using the methodology specified in Schedule 5.
5 A monitoring local authority shall as soon as is practicable and in any event, within 28 days of being requested to do so by a relevant person in relation to a Type B supply, or a consumer of such a supply serving premises in their area, take and analyse a sample from the supply representative of the quality of water intended for human consumption purposes throughout the year for compliance with the parameters specified in regulation 7(3).
6 Without prejudice to the monitoring powers and duties in this regulation, a monitoring local authority shall have power to take and analyse a sample from a Type B supply in order to—
(a) confirm or clarify the results of the analysis of a previous sample;
(b) ascertain the effectiveness of remedial action taken in relation to the supply (whether or not such action was taken following service of a notice under section 76G of the 1980 Act).
Section 76G was added by the Water Act 1989, Schedule 2, paragraph 1.

30 Additional Monitoring
1 This regulation applies to any Type B supply sampled by a monitoring local authority in accordance with regulation 29.
2 A monitoring local authority may sample every appropriate Type B supply in its area in respect of any property, element, micro-organism, parasite or substance which fulfils the conditions specified in paragraph (3).
3 The conditions specified in this paragraph are that—
(a) the supply may have or contain a property, element, micro-organism, parasite or substance not listed in Table C of Schedule 2; and
(b) the monitoring local authority reasonably believes that the concentration, amount or number of the property, element, micro-organism, parasite or substance may be such that it may (whether alone or in combination with a parameter or any other property, element, micro-organism, parasite or substance) cause the supply to fail to satisfy the provisions of regulation 7(3).
4 A monitoring local authority may cause to be taken such samples at such frequency as it considers appropriate having regard to any anticipated risk of danger to human health, and which are representative of the quality of water intended for human consumption purposes throughout the year.

PART IX PRIVATE WATER SUPPLIES: SAMPLING, ANALYSIS AND CHARGING

31 Collection and analysis of samples
1 A monitoring local authority shall secure, so far as is reasonably practicable, that in taking, handling, transporting, storing and analysing any sample taken for the purposes of these Regulations, or causing any such sample to be taken, handled, transported, stored and analysed, the appropriate requirements are satisfied.
2 In paragraph (1), “the appropriate requirements” means such of the following requirements as are applicable—
(a) that the sample is representative of the quality of the water intended for human consumption purposes at the point of compliance specified in regulation 7(4) or (5) at the time of sampling;
(b) that the sample is not contaminated when being taken or subsequently;
(c) that the sample is kept at such temperature and in such conditions as will secure that there is no material alteration of the concentration or value or specification for the measurement or observation of which the sample is intended;
(d) that the sample is analysed as soon as may be after the time it has been taken—
(i) by, or under the supervision of, a person who is competent to perform that task; and
(ii) with the use of such equipment as is suitable for the purpose;
(e) that any laboratory at which samples are analysed has a system of analytical quality control that is subject from time to time to checking by a person who is–
(i) not under the control of either the laboratory or the monitoring local authority; and
(ii) approved by the Scottish Ministers for that purpose.
3 A monitoring local authority shall maintain such records as are sufficient to enable it to establish, in relation to each sample taken for the purposes of these Regulations that such of the appropriate requirements as are applicable to that sample have been satisfied.
4 Subject to paragraph (6), for the purpose of establishing, within acceptable limits of deviation and detection, whether the sample contains concentrations or values or specifications which contravene the prescribed concentrations or values or specifications, or exceed the specifications for indicator parameters—
(a) the method of analysis specified in column (2) of Table A in Schedule 5 shall be used for determining compliance with the parameter specified in relation to that method in column (1);
(b) the method of analysis used for determining compliance with a parameter specified in column (2) of Table B in Schedule 5 must be capable, at the time of use—
(i) of measuring concentrations or values or specifications equal to the parametric value with the trueness and precision specified in relation to that parameter in columns (3) and (4) of that Table; and
(ii) of detecting the parameter at the limit of detection specified in relation to that parameter in column (5) of that Table;
(c) the method of analysis used for determining compliance with hydrogen ion parameter must be capable, at the time of use, of measuring concentrations equal to the parametric value with a trueness of 0.2 pH units and a precision of 0.2 pH units; and
(d) the method of analysis used for odour and taste parameters must be capable, at the time of use, of measuring values equal to the parametric value with a precision of 1 dilution number at 25°C.
5 For the purposes of paragraph (4)—
“limit of detection” is to be calculated as—
(a) three times the relative within batch standard deviation of a natural sample containing a low concentration of the parameter; or
(b) five times the relative within batch standard deviation of a blank sample; and
“precision” (the random error) is to be calculated as twice the standard deviation (within a batch and between batches) of the spread of results about the mean; and
“trueness” (the systematic error) is to be calculated as the difference between the mean value of the large number of repeated measurements and the true value.
6 Subject to paragraph (8), the Scottish Ministers may, on the application of any person, authorise a method of analysis other than that specified in paragraph (4)(a) (“the prescribed method”).
7 An application for the purpose of paragraph (6) shall be made in writing and shall be accompanied by–
(a) a description of the method of proposed analysis; and
(b) the results of the tests carried out to demonstrate the reliability of that method and its equivalence to the prescribed method.
8 The Scottish Ministers shall not authorise the use of the method proposed in an application under paragraph (6) unless they are satisfied that the results obtained by the use of that proposed method are at least as reliable as those produced by the use of the prescribed method.
9 An authorisation under paragraph (6) may be subject to such conditions as the Scottish Ministers think fit.
10 The Scottish Ministers may at any time by notice in writing to the person to whom an authorisation under paragraph (6) has been given, revoke the authorisation; and no such notice shall be served later than 3 months before the date on which the revocation is stated to take effect.
11 Within 28 days of the results of analysis of any sample of a private water supply taken from any premises being available to the monitoring local authority which took the sample, or caused it to be taken, the monitoring local authority shall notify the relevant person of the results of that analysis, and any other person who is to be charged under regulation 33 for the taking and analysis of the sample from those premises.

32 Sampling of private water supplies: further provision
As soon as a monitoring local authority has reasonable grounds for believing that any element, organism or substance, other than residual disinfectant or a parameter, whether alone or in combination with a parameter or any other element, micro-organism, parasite or substance, may cause a private water supply serving premises located in the area of that authority to be a supply which does not satisfy—
(a) the provisions of Part IV; or
(b) if a departure has been authorised under Part V in respect of a Type A supply, those provisions as read with the terms of that authorisation,
it shall take, or cause to be taken, sufficient samples from the private water supply in respect of that element, organism or substance, in order to establish whether the supply is wholesome.

33 Charges for sampling, analysis and risk assessment
1 A local authority may charge a person for expenses reasonably incurred by it—
(a) in respect of a Type A supply, for—
(i) sampling a supply in accordance with these Regulations, up to a maximum of £70 per visit to any premises for that purpose;
(ii) the analysis of samples—

SCHEDULE 3 CIRCUMSTANCES AND CONDITIONS TO BE CONSIDERED BY A MONITORING LOCAL AUTHORITY: DECISION ON AUDIT MONITORING
Regulation 26
(1) Where a monitoring local authority carries out an investigation in relation to a Type A supply for the purposes of regulation 26, it shall do so in accordance with the provisions of this Schedule and shall take into account the matters specified in Schedule 4.
(2) Where a monitoring local authority considers that one or more of the parameters listed in the Table in this Schedule is not likely to be present in a Type A supply in its area in concentrations which could lead to the risk of a breach of the parametric value in respect of the parameters specified in Table B of Schedule 2, it shall undertake such investigations as are considers reasonable to satisfy itself–
(a) that the circumstances referred to in column 3 of the Table in this Schedule in respect of that parameter do not exist; and
(b) whether any of the conditions referred to in column 4 of the Table in this Schedule in respect of that parameter, apply.
(3) Where a monitoring local authority is satisfied, as a result of its investigations under paragraph (2), that in respect of the supply, one or more of the parameters referred to in column 2 of the Table in this Schedule is not likely to be present in that supply in concentrations which could lead to the risk of a breach of the said parametric value in respect of such parameters, it may make a decision in accordance with regulation 26.

Table
(1) Item No.	(2) Parameter	(3) Circumstances in which parameter is likely to be present	(4) Conditions to be satisfied before a decision may be made
(1)	Acrylamide	Residual acrylamide monomer occurs in polyacrylamide coagulants used in drinking water treatment. May also be used as grouting agents (polyacrylamide) in wells/borehole linings.	Coagulation is not practised. Grouting agents are present but that they do not have an acrylamide content.
(2)	Aluminium	Aluminium salts are widely used in water treatment as coagulants to reduce organic matter, colour, turbidity and micro organism levels.	Coagulation is not practised.
(3)	Antimony	Most common source of antinomy in drinking water appears to be dissolution from metal plumbing fittings.	If the monitoring local authority is satisfied that antimony is not present at or above 75% of PCV then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(4)	Arsenic	Arsenic is introduced into drinking water sources primarily through the dissolution of naturally occurring minerals and ores. Arsenic in drinking water is a significant source of health effects in some areas. Arsenic is considered to be a high-priority substance for screening in drinking water sources. Concentrations are highly dependent on the depth to which a well or borehole is sunk.	If the monitoring local authority is satisfied that arsenic is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(5)	Benzene	Benzene is used principally in the production of other organic chemicals. As benzene is present in petrol, vehicular emissions constitute the main source of the chemical in the environment. Benzene may be introduced into water by industrial effluents and atmospheric pollution.	Where the source of the supply comprises groundwater (well, spring, borehole or similar) the area in which the source is located must be an area devoid of industrial activity (current or historic) or hydrocarbon stores (current or historic) eg, underground petroleum tanks. Where the source of the supply comprises surface water, the area in which the source is located must be an area remote from areas of industrial activity (current or historic) or remote from areas of high vehicular activity.
(6)	Benzo(a)pyrene	See PAH	See PAH
(7)	Boron	Boron is found naturally in groundwater but its presence in surface water is frequently a consequence of the discharge of treated sewage effluent, in which it arises from its use in detergents, to surface water.	If the monitoring local authority is satisfied that Boron is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(8)	Bromate	Bromate is not normally found in water but may be formed during ozonation when the bromide ion is present in water.	No ozonation or chlorination to be undertaken on the supply.
		Under certain conditions bromate may also be found in concentrated hypochlorite solutions used to disinfect drinking water including electrolytic production of chlorine from sodium chloride	
(9)	Cadmium	Cadmium is released into the environment in wastewater. Diffuse pollution is also caused by contamination from fertilizers and local air pollution. Contamination in drinking water may also be caused by impurities in the zinc of galvanised pipes and solders and some metal fittings.	If the monitoring local authority is satisfied that Cadmium is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(10)	Chromium	Chromium is widely distributed in the Earth’s crust. Soils and rocks may contain small amounts.	If the monitoring local authority is satisfied that Chromium is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(11)	Copper	Copper concentrations in drinking water vary widely with the primary source most often being the corrosion of interior copper plumbing. Copper concentrations in treated water often increase during distribution, especially in systems with an acid pH or high carbonate waters with an alkaline pH. Consumption of standing or partially flushed water from a distribution system that includes copper pipes or fittings can considerably increase total daily copper exposure, especially for infants fed formula reconstituted with tap water.	If the monitoring local authority is satisfied that Copper is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(12)	Cyanide	Cyanides are occasionally found in drinking water primarily as a consequence of industrial contamination.	If the monitoring local authority is satisfied that Cyanide is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(13)	1,2 dichloroethane	1,2 dichloroethane is used mainly as an intermediate in the production of vinyl chloride and other chemicals and to a lesser extent as a solvent. It may enter surface waters via effluents from industries that manufacture or use the substance. It may also enter groundwater, where it persists for long periods, following disposal in waste sites.	If the monitoring local authority is satisfied that 1,2 dichloroethane is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(14)	Epichlorohydrin	Epichlorohydrin is used for the manufacture of glycerol, unmodified epoxy resins and water treatment resins. It is also found in some polyamine flocculants.	Coagulation is not practiced using polyamine flocculants. If ion exchange resins are present in the system then it should be sampled for against the prescribed frequency specified in Schedule 2.
(15)	Fluoride	Fluoride is present in a number of minerals. Fluoride may also be present in phosphate fertilizers.	If the monitoring local authority is satisfied that Fluoride is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(16)	Iron	Iron is found in natural fresh waters. Iron may also be present in drinking water as a result of iron coagulants or the corrosion of steel and cast iron pipes during water distribution.	If the monitoring local authority is satisfied that Iron is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(17)	Lead	Lead is rarely present in tap water as a result of its dissolution from natural sources. The presence of lead is primarily from household plumbing systems containing lead in pipes, solder, fittings or the service connections to homes.	If the monitoring local authority is satisfied that Lead is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(18)	Manganese	Manganese is naturally occurring in many surface and groundwater sources, particularly in anaerobic or low oxidation conditions. Manganese greensands are used in some locations for potable water treatment.	If the monitoring local authority is satisfied that Manganese is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(19)	Mercury	Mercury can be used in the electrolytic production of chlorine.	If electrolytic production of chlorine is used as part of the treatment process the supply should be sampled as specified in Schedule 2;
			if electrolytic production of chlorine is not used as part of the treatment process, and if the monitoring local authority is satisfied that mercury is not present at or above 75% of PCV, then an exemption under regulation 26 may be granted, otherwise it should be sampled for at the frequency specified in Schedule 2.
(20)	Nickel	Nickel may be present as a result of plumbing fittings eg from nickel- or chromium-plated taps.	If the monitoring local authority is satisfied that Nickel is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(21)	Nitrate	Nitrate is used mainly in inorganic fertilisers. The nitrate concentration in groundwater and surface water is normally low but can reach high levels as a result of leaching or runoff from agricultural land or contamination from human or animal wastes as a consequence of oxidation of ammonia or similar sources.	If the supply is in an area where agricultural fertilisers are used then the supply should be sampled as specified in Schedule 2; if the supply is in an area where agricultural fertilisers are not used, and if the monitoring local authority is satisfied that nitrate is not present at or above 75% of PCV, then an exemption under regulation 26 may be granted, otherwise it should be sampled for at the frequency specified in Schedule 2.
(22)	Nitrite	Nitrite is formed during the decomposition of organic matter but high concentrations are usually associated with poor control of chloramination or chlorine disinfection of water containing significant amounts of ammonium ions.	If the monitoring local authority is satisfied that Nitrite is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(24)	Pesticides	See definition of “pesticides and related products” in regulation 2(1). The range of pesticides and related products that may be being used in any one area should be assessed on an individual supply basis.	If the monitoring local authority is satisfied that Pesticides are not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise they should be sampled for at the frequency specified in Schedule 2.
(25)	Pesticides – Total	“Pesticides – Total” means the sum of the concentrations of the individual pesticides detected and quantified in the monitoring procedure.	See Pesticides.
(26)	Polycyclic Aromatic Hydrocarbons (PAH)	The main source of PAH contamination in drinking water is usually the coal-tar coating of drinking water distribution pipes used to protect the pipes from corrosion.	If the monitoring local authority is satisfied that PAH are not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise they should be sampled for at the frequency specified in Schedule 2.
(27)	Selenium	Selenium is present in the Earth’s crust, often in association with sulphur-containing minerals and hence the concentration in drinking water will vary with local geology and geography.	If the monitoring local authority is satisfied that Selenium is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(28)	Silver	Silver may be used in some water treatment devices where it is used for disinfection purposes.	If the monitoring local authority is satisfied that Silver is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(29)	Sodium	Concentrations in potable water are typically low but some water softeners can add significantly to the sodium content of drinking water.	If the monitoring local authority is satisfied that Sodium is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(30)	Sulphate	Sulphates occur naturally in numerous minerals and are used commercially but the highest levels found in groundwaters are from natural sources. Sulphates may occur in surface waters that have received industrial discharges.	If the monitoring local authority is satisfied that Sulphate is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(31)	Tetrachloroethene and Trichloroethene	These chemicals are used primarily as solvents in dry cleaning industries and as degreasing solvents.	If the monitoring local authority is satisfied that Tetrachloroethene and Trichloroethene are not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise they should be sampled for at the frequency specified in Schedule 2.
(32)	Tetrachloromethane	Chlorinated organic compound (also known as carbon tetrachloride) that is a very efficient solvent for fats and greases, and was at one time the main constituent of household dry-cleaning fluids and of fire extinguishers used with electrical and petrol fires.	If the monitoring local authority is satisfied that Tetrachloromethane is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(33)	Total indicative dose	Routine monitoring for Total indicative dose is achieved through screening for gross alpha and gross beta.	If a monitoring local authority is satisfied that on the basis of other monitoring carried out, the Total indicative dose in a supply is well below the prescribed value, the authority may seek a regulation 24 notice from the Scottish Ministers confirming that the supply need not be monitored in respect of Total indicative dose.
(34)	Trihalomethanes – Total	These compounds are generated principally as by-products of the chlorination of drinking water, being formed from naturally occurring organic compounds.	No chlorination is undertaken on the supply.
(35)	Tritium	Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity, and in special production reactors, where the isotope Lithium-6 is bombarded to produce Tritium.	If a monitoring local authority is satisfied that on the basis of other monitoring carried out, the level of Tritium in a supply is well below the prescribed value, the authority may seek a regulation 24 notice from the Scottish Ministers confirming that the supply need not be monitored for Tritium.
(36)	Vinyl chloride	Vinyl chloride is used primarily for the production of PVC. When unplasticised PVC is in contact with water it is possible for the vinyl chloride monomer to be released into the water. Unplasticised PVC pipes should not be used for drinking water supplies. This is controlled by product specification.	Unplasticised PVC pipes not present. If the monitoring local authority is satisfied that Vinyl chloride is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.
(37)	Zinc	Traces of zinc occur naturally in many water sources but significant concentrations may occur as a consequence of the use of brass fittings and galvanised iron pipes.	If the monitoring local authority is satisfied that Zinc is not present at or above 75% of PCV, then an exemption may be granted under regulation 26, otherwise it should be sampled for at the frequency specified in Schedule 2.

(This note is not part of the Regulations)
These Regulations supplement Part VIA (quality of water) of the Water (Scotland) Act 1980 (“the 1980 Act”) and are directed at the achievement of the objective set out in article 1(2) of Council Directive 98/83/EC (O.J. No. L 330, 5.12.98, p.32) on the quality of water intended for human consumption (“the Directive”), namely, to protect human health from the adverse effects of any contamination of water intended for human consumption, by ensuring that it is wholesome and clean. The Regulations implement the Directive insofar as it concerns private water supplies (within the meaning of regulation 2(1)).
Part I of the Regulations provides for the Regulations to come into force on 3rd July 2006, and defines terms that are used in the Regulations. In particular, regulation 2(1) defines “private water supplies”, which comprise “Type A” and “Type B” supplies.
Part II contains provisions in relation to the determination of a person to be a “relevant person”, and for an appeal to the sheriff against that determination.
Part III excludes certain private water supplies from the application of the Regulations (except regulations 34(2) and 35)
Part IV contains provisions in relation to the classification of private water supplies and for the review of classifications.
Part V prescribes standards of wholesomeness in respect of Type A and Type B supplies for human consumption purposes. A supply is regarded as wholesome if it contains concentrations or values in respect of the properties, parameters, organisms and substances that do not contravene prescribed maxima or minima.
Part VI makes provision further to article 9 of the Directive to exempt Type A supplies from the wholesomeness requirements of Part V in specified circumstances, and for specified periods.
Regulation 8 requires a relevant person to make an application for an authorised departure (from the requirements of Part V) where a Type A supply is believed to fail, or likely to fail, a requirement of regulation 7(2), and specifies the matters to be included in such an application, and who requires to be notified of application. Regulation 9 provides for the application process in relation to authorised departures.
Article 9(1) of the Directive recognises that in certain circumstances it may not be possible to bring a Type A supply up to the wholesomeness standards of Part V by the end of the departure period specified under regulation 9 and regulation 10 makes provision for a second departure period. Article 9(2) of the Directive recognises that in exceptional circumstances, compliance with the requirements of Part V may not be achieved by the end of a second departure period and regulation 11 makes provision in this regard. On being satisfied there are grounds for a third departure, the Scottish Ministers shall seek from the European Commission a decision whether to grant a third departure.
Regulation 13 makes provision in relation to the persons to be notified when a departure is granted and regulation 14 makes provision in relation to the refusal of a departure, and the giving of reasons for such a refusal.
Part VI contains provision in relation to Type A supplies. It requires a monitoring local authority to carry out a risk assessment of every Type A supply in its area, and for the results of such an assessment to inform any remedial action as may be required under regulation 17 or 18. A monitoring local authority is also required to identify whether such supplies meet the requirements of Part V (or those requirements as read with the terms of any authorisation granted under Part VI). Where those requirements are not met, regulations 17 and 18 require the monitoring local authority to notify the relevant person in relation to the supply and advise of any failure attributable to a domestic distribution system. Where a failure is attributable to a domestic distribution, the responsible person in relation to that system is required to notify consumers of the supply of the steps considered by the authority necessary or desirable to take in the interests of their health. Where a failure affects a supply of water to the public, the responsible person requires to prominently display a notice advising of the steps considered by the authority necessary or desirable for consumers of the supply to take in the interests of their health.
Part VII contains provisions in relation to the monitoring of Type A supplies.
Regulation 21 requires a monitoring local authority to take and analyse the number of samples specified in Tables A and B in Schedule 2 for parameters, organisms and substances. It also makes specific provision for monitoring supplies from tankers.
Regulation 23 provides for the number of samples of Type A supplies which a monitoring local authority requires to take, and specifies the circumstances in which a reduced sampling regime applies. Regulation 24 makes provision in relation to the monitoring of tritium and total indicative dose. Regulation 25 gives powers to a monitoring local authority to sample Type A supplies for properties, elements, micro-organisms and substances not listed in Schedule 1. Regulation 26 specifies the circumstances in, and parameters in respect of which a monitoring local authority may make a decision in relation to the parameters to be subject to audit monitoring (regulation 20).
Part VIII contains provisions in relation to Type B supplies. Regulation 27 makes provision equivalent to regulation 16 (in relation to risk assessments carried out in respect of Type A supplies). Regulation 18 enables a monitoring local authority to investigate a Type B supply in its area, and Regulations 29 to 31 make provision in relation to the monitoring and sampling of Type B supplies.
Part IX contains provisions in relation to the sampling of private water supplies. Regulation 31 specifies the mechanisms for sampling, including the transportation and analysis of samples. Regulation 32 enables a monitoring local authority to take and analyse a sample from a private water supply at any time and in respect of any element, organism or substance (whether or not specified in any Schedule to the Regulations) in order to establish whether the supply is wholesome.
Regulation 33 makes provision in relation to the charges a local authority may levy in the exercise of its powers and duties under the Regulations.
Part X contains provisions an the information and records to be maintained by local authorities on private water supplies in their area and premises served by such supplies. Regulation 34 requires local authorities to hold information in the form of a register and paragraph (1) of that regulation prescribes the information to be contained in that register. Regulation 35 specifies the circumstances in which information in the register may be inspected or obtained and requires a copy of the register to be provided to SEPA annually. Regulation 36 requires all commercial premises and premises which are used as part of a public activity and which are supplied with a private water supply to prominently display at those premises a notice provided by the local authority for that purpose.
Part X (regulation 36) contains revocation and savings provisions.
There are five Schedules to the Regulations. Schedule 1 comprises Tables A to D (together with the associated notes thereto) and specifies the prescribed concentrations and values for the range of parameters which require to be investigated to determine whether a private water supply is wholesome. Schedule 2 comprises Tables A to C, and specifies the parameters, monitoring and sampling frequencies for check and audit monitoring Type A supplies, and the monitoring parameters for Type B supplies. Schedule 3 specifies the matters a local authority must consider before making a decision for the purposes of regulation 26. Schedule 4 contains the matters which a local authority requires to take into account when undertaking a risk assessment for the purposes of regulations 16 or 27. Schedule 5 prescribes the analytical methodology against which samples taken under the Regulations must be analysed.
The Regulatory Impact Assessment in relation to these Regulations has been placed in the library of the Scottish Parliament and a copy can be obtained from the Water Division, Scottish Executive Environment and Rural Affairs Department (SEERAD), Victoria Quay, Leith, Edinburgh, EH6 6QQ.
