Derogations from the water quality standards
15. Schedule 5 makes provision for derogations.

Duty of care: supplies of water
16. A person, in relation to a supply of water, must not take any action which has the effect of allowing any deterioration of the quality of the water (in so far as that is relevant for the protection of human health).

Duty of care: substances and materials
17. A person who, in relation to a supply of water, modifies any part of a private water supply system or introduces any substance to the water supplied (for purposes in connection with the distribution or preparation of the water) must ensure that no substance or material used or introduced for those purposes (or any impurity associated with any such substance or material)—
(a) remains in the water (including, in particular, at the point of compliance) in concentrations higher than is necessary for the purpose of their use; or
(b) reduces the protection of human health otherwise provided for by these Regulations.

PART 5 MONITORING AND ANALYSIS

Monitoring
18. (1) An enforcing authority must ensure that regular monitoring of the quality of water in its area is carried out to check that water available to consumers meets the water quality standards.
(2) Where the enforcing authority has reason to suspect that the water contains a micro-organism, parasite or substance (in number or concentration) which—
(a) poses a potential danger to human health; and
(b) is not one of the parameters in Table A, Table B or Table C,
the enforcing authority must ensure that monitoring is carried out to establish whether, at the point of compliance, the micro-organism, parasite or substance poses such a potential danger.
(3) Where disinfection forms part of the preparation or distribution of the water, the enforcing authority must take all measures necessary to ensure that—
(a) the efficiency of the disinfection treatment applied is verified; and
(b) any contamination from disinfection by-products is kept as low as possible without compromising the disinfection.
(4) The enforcing authority must ensure that the monitoring is carried out so as to ensure that the measured values are representative of the quality of the water consumed throughout the year.

Monitoring programmes
19. (1) An enforcing authority must prepare and implement a monitoring programme for each supply zone (or part of a supply zone) in so far as the supply zone (or the part of it) relates to—
(a) water introduced into, and supplied through and from, a private water supply system to premises within the area of the enforcing authority; or
(b) water produced within the supply zone (or the part of it) which is supplied from a tanker or in bottles or containers to a point of compliance within the authority’s area.
(2) Each monitoring programme prepared by the enforcing authority must—
(a) meet its obligations under regulation 18;
(b) meet the minimum requirements in Parts A to D of schedule 3;
(c) accord with the monitoring requirements in Parts E and F of schedule 3; and
(d) comply with such other requirements as may be specified in directions given to the enforcing authority under regulation 36(1).
(3) The enforcing authority must—
(a) determine the sampling points (for the purposes of each monitoring programme); and
(b) ensure that these sampling points meet the relevant requirements in schedule 3.

Methods of analysis
20. (1) Each enforcing authority must ensure that the method used for the analysis of a parameter in a sample of water pursuant to regulation 18—
(a) complies with the specifications for the analysis of the parameter in schedule 4; or
(b) produces results which are at least as reliable as those produced by a method which complies with the specifications for the analysis of the parameter in schedule 4.
(2) A method of analysis in relation to which paragraph (1)(b) applies may be used only if—
(a) the enforcing authority has provided all relevant information concerning the method and its equivalence to—
(i) the Drinking Water Quality Regulator for Scotland; and
(ii) the Scottish Ministers; and
(b) the Drinking Water Quality Regulator for Scotland—
(i) is satisfied that it can be demonstrated that the alternative method produces results which are at least as reliable as those produced by a method which complies with the specifications for the analysis of the parameter in schedule 4; and
(ii) has confirmed this by notice to the enforcing authority.

PART 6 INVESTIGATION AND REMEDIAL ACTION

Investigation and remedial action
21. Each enforcing authority, in relation to a supply of water, must ensure that—
(a) a failure of the water to meet a parametric value in Table A, Table B or Table C is immediately investigated in order to identify the cause, and assessed to determine whether the failure poses a risk to human health which requires remedial action;
(b) if, for any reason, the supply of water poses a potential danger to human health—
(i) remedial action is taken as is necessary to protect human health (including, where appropriate, action to prohibit the supply of water or to restrict its use); and
(ii) consumers are informed promptly of the danger and given the necessary advice; and
(c) subject to regulation 22, remedial action is taken as soon as possible (after any such failure) to restore the quality of the water so that it meets the parametric value, with priority given to enforcement action having regard among other things to the extent to which the parametric value was exceeded and the potential danger to human health.

Remedial action to restore water quality: particular cases
22. (1) In the case of a failure to meet a parametric value in Table C, the duty to take action under regulation 21(c) applies only in so far as action is necessary to protect human health.
(2) The duty of an enforcing authority to take remedial action under regulation 21(c) does not apply in relation to a failure referred to in regulation 21(a) (other than a failure to meet a parametric value for radon, tritium or indicative dose) in a case where it can be established by the enforcing authority that the failure was due to a domestic distribution system or its maintenance.
(3) Where paragraph (2) applies and there is a risk that water supplied through or from any part of the domestic distribution system will, at the point of compliance, contain a parameter which exceeds a parametric value in Table A, Table B or Table C, the enforcing authority must ensure—
(a) that appropriate measures are taken to reduce or eliminate the risk, such as—
(i) advising the person who is responsible for the domestic distribution system of any possible remedial action that the person could take to reduce or eliminate the risk; or
(ii) treating the water before it is supplied to the domestic distribution system so that the parametric value in question is not exceeded at the point of compliance; and
(b) that each consumer of the water is—
(i) informed of the risk; and
(ii) advised of any possible additional remedial action that they should take.

Remedial action to restore water quality: notification of risk, etc.
23. (1) The enforcing authority must ensure that, where remedial action is taken in relation to water pursuant to regulation 21(c), consumers of the water and any other person affected, are—
(a) notified of the risk (if any) to human health and the remedial action taken; and
(b) advised of any additional precautionary measures that may be needed for the protection of human health.
(2) The duty to notify consumers in paragraph (1) does not apply if the enforcing authority confirms, by notice to the Drinking Water Quality Regulator for Scotland, that the remedial action was taken in response to a failure to meet a parametric value (other than a failure to meet a parametric value for radon, tritium or indicative dose) which it considers to be trivial.

PART 7 INFORMATION AND REPORTING

Duty to provide information to consumers
24. (1) A person who owns premises served with a supply of water must ensure that adequate and up-to-date information on the quality of the water is available to the consumers of the water.
(2) If the premises are used for the purposes of a commercial or public activity, the owner must ensure that a notice is prominently displayed in a location which will bring the information contained in the notice to the attention of any person using the premises.
(3) The notice must include such information as the enforcing authority may, by notice to the owner of the premises in question, require about the source, quality or treatment of the water.

Information for certain public authorities
25. By 31st March in each year, an enforcing authority must provide to the following persons adequate and up-to-date information on the quality of the water available to the consumers of the water in its area for the preceding year:—

Where appropriate the sampling and monitoring methods must be applied in accordance with any guidelines under Article 7(4) of Council Directive 98/83/EC on the quality of water intended for human consumption OJ L 330, 5.12.1998, p.32, as amended by Regulation (EC) No 1882/2003 of the European Parliament and of the Council (OJ L 284, 31.10.2003, p.1), Regulation (EC) No 596/2009 of the European Parliament and of the Council (OJ L 188, 18.7.2009, p.14), Commission Directive (EU) 2015/1787 (OJ L 260, 7.10.2015, p.6) and Corrigendum (OJ L 111, 20.4.2001, p.31). . Each enforcing authority in relation to the water must take account of the occurrence of peak levels that may cause adverse effects on human health.
Note 4: When implementing measures to achieve compliance with this parametric value, each enforcing authority (in relation supplies of water to premises) must progressively give priority where lead concentrations in the water are highest.
Note 5: The additional parametric value of 0.10 mg/l applies only if the water is subject to treatment to improve its quality. The point of compliance for this additional parametric value is the point at which the water flows out from the treatment works.
Note 6: “Pesticide” means an organic insecticide, organic herbicide, organic fungicide, organic nematocide, organic acaricide, organic algicide, organic rodenticide, organic slimicide, a related product (including growth regulator) and any relevant metabolite, degradation or reaction product. Only those pesticides which are likely to be present in a supply of water need to be monitored.
Note 7: “Other pesticide” means a pesticide other than aldrin, dieldrin, heptachlor and heptachlor epoxide. The parametric value applies to each “other pesticide” individually.
Note 8: The parametric value for this parameter is the sum of all individual pesticides detected and quantified in the monitoring procedure.
Note 9: The parametric value for this parameter is the sum of the concentrations of benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene and indeno(1,2,3-cd)pyrene.
Note 10: The parametric value for this parameter is the sum of the concentrations of tetrachloroethene and trichloroethene.
Note 11: The parametric value for this parameter is the sum of chloroform, bromoform, dibromochloromethane and bromodichloromethane.

(3) The Drinking Water Quality Regulator for Scotland may, by notice to the enforcing authority, revoke with immediate effect any consent given by it under sub-paragraph (2)(b).

PART D Sampling methods and sampling points
1. (1) Sampling points, in relation to water, must be determined by the enforcing authority so as to ensure that the results of the analysis of discrete water samples collected at those points will establish whether or not the water meets the water quality standards at each point of compliance.
(2) In the case of a supply of water in pipes to any premises used for a commercial or public activity, the sampling points must include a point of compliance within each premises.
(3) In the case of a supply of water in pipes to premises (including any premises used for a commercial or public activity), an enforcing authority may take samples of the water within the supply zone or at a treatment works for a particular parameter—
(a) if it can be demonstrated that there would be no adverse change to the measured value of the parameter concerned; and
(b) in the case of any premises used for a commercial or public activity, the Drinking Water Quality Regulator for Scotland, by notice to the enforcing authority, consents to the samples being taken within the supply zone or at the treatment works for the particular parameter, and that consent has not been revoked under sub-paragraph (6).
(4) In a case where an enforcing authority may take samples of the water within the supply zone or at a treatment works for a particular parameter, the point at which the samples are taken is to be treated for the purposes of these Regulations as the point of compliance for the parameter.

PART E Radioactive substances

General principles and monitoring frequencies
1. (1) Subject to sub-paragraph (2), each enforcing authority in relation to a supply of water must ensure that the water is monitored for radon, tritium and indicative dose.
(2) Where the Scottish Ministers, by notice to the enforcing authority, confirm that they have established that radon, tritium or, as the case may be, indicative dose is not likely to be present in relation one or more supplies of water, for a period specified in the notice, in concentrations which could exceed the parametric value for the parameter, the enforcing authority is not required to monitor any such supply of water for the parameter during the period specified.
(3) In case of naturally occurring radionuclides—
(a) where previous results show that the concentration of radionuclides in one or more supplies of water is stable, the minimum sampling and analysis frequencies are to be decided by the Scottish Ministers, and confirmed by notice to the enforcing authority, taking into consideration the risk to human health; and
(b) where the Scottish Ministers, by notice to the enforcing authority, confirm that they are satisfied (on the basis of representative surveys, monitoring data or other reliable information) that levels of radon, tritium and the calculated indicative dose in one or more supplies of water will, for a period specified in the notice, remain below the parametric value for each parameter at the point of compliance, the enforcing authority is not required to monitor any such supply for these parameters during the period specified.
(4) Where sub-paragraph (3)(b) applies, the Scottish Ministers must communicate the grounds for the decision to the European Commission and provide the Commission with the necessary documentation supporting that decision, including the findings of any surveys, monitoring or investigations carried out.

Radon
2. (1) Subject to paragraphs 5 and 6, the enforcing authority must ensure that representative surveys are undertaken to determine the scale and nature of likely exposures to radon in the water originating from different types of ground water sources and wells in different geological areas.
(2) The surveys must be designed in such a way that underlying factors, and especially the geology and hydrology of the area, radioactivity of rock or soil, and well type, can be identified and used to direct further action to areas of likely high exposure.
(3) Monitoring of radon concentrations must be carried out if the enforcing authority has reason to believe, on the basis of the results of the representative surveys or other reliable information, that the parametric value for radon might be exceeded.

Tritium
3. (1) Subject to paragraphs 5 and 6, the enforcing authority must monitor the water for tritium where—
(a) an anthropogenic source of tritium or other artificial radionuclides is present within the catchment area for the supply; and
(b) it cannot be shown on the basis of other surveillance programmes or investigations that the level of tritium is below the parametric value for tritium.
(2) Where monitoring for tritium is required by sub-paragraph (1), samples must be taken in accordance with paragraph 6.
(3) If the concentration of tritium in any such sample exceeds the parametric value for tritium, the enforcing authority must carry out an investigation of the presence of other artificial radionuclides.

Indicative dose
4. (1) The enforcing authority must monitor the water for indicative dose where—
(a) a source of artificial radioactivity or elevated natural radioactivity is present; and
(b) it cannot be shown on the basis of other representative monitoring programmes or other investigations that the indicative dose is below the parametric value for that parameter.
(2) Where sub-paragraph (1) requires monitoring (of radionuclide levels) only in relation to a source of artificial radioactivity, samples must be taken in accordance with paragraph 6.
(3) Where sub-paragraph (1) requires monitoring (of radionuclide levels) in relation to a source of elevated natural radioactivity, the enforcing authority must determine the frequency of the monitoring required of—
(a) gross alpha activity;
(b) gross beta activity; or
(c) individual natural radionuclides,
depending on the screening strategy adopted pursuant to Part F of this schedule.
Words in sch. 3 Pt. E para. 4(3) substituted (26.10.2017) by The Public and Private Water Supplies (Miscellaneous Amendments) (Scotland) Regulations 2017 (S.S.I. 2017/321), regs. 1, 4(6)
(4) Where sub-paragraph (3) applies, the frequency determined may vary from a single check measurement to the frequency which would otherwise apply by virtue of paragraph 6.
(5) Where a single check for natural radioactivity is specified under sub-paragraph (3), the enforcing authority must carry out a further check if any change occurs in relation to the supply which is likely to influence the concentrations of radionuclides in the supply.

Water treatment
5. Where the water is treated to reduce the level of radionuclides, the enforcing authority must monitor the water for indicative dose, radon and tritium in accordance with paragraph 6 to verify the continued efficacy of that treatment.

Minimum sampling and analysis frequencies
6. The minimum sampling and analysis frequency for the monitoring of radon, tritium and indicative dose in water (where required by this schedule) from a private water supply system or from a tanker or used in a food production undertaking is set out in the following table.
Volume of water (in m3) distributed or produced each day within a supply zone (Note 1)		Number of samples per year (Notes 2 and 3)
> 0	≤ 100	1
> 100	≤ 1,000	1
> 1,000	≤ 10,000	1, plus 1 for each 3,300 m3/day and part thereof of the total volume
> 10,000	≤ 100,000	3, plus 1 for each 10,000 m3/day and part thereof of the total volume
> 100,000		10, plus 1 for each 25,000 m3/day and part thereof of the total volume
Note 1: The volumes are calculated as averages taken over a year. The number of inhabitants in a supply zone may be used instead of the volume of water to determine the minimum frequency, assuming water consumption of 200 litres/day per person.		
Note 2: As far as possible, the number of samples must be distributed equally in time and location.		
Note 3: In the event of intermittent short-term supply the monitoring frequency of water distributed by tankers must be decided by each enforcing authority in relation to the water.		

Averaging
7. Where the parametric value for radon, tritium or, as the case may be, indicative dose is exceeded in a sample of the water, the Drinking Water Quality Regulator for Scotland must specify, by notice to the enforcing authority, the extent of resampling necessary to ensure that the measured values are representative of an average activity concentration for a full year.

PART F Indicative dose

Monitoring for compliance with the indicative dose
1. (1) Each enforcing authority, in relation to water, may use reliable screening strategies to indicate the presence of radioactivity in the water.
(2) These strategies may include screening for—
(a) certain radionuclides or an individual radionuclide; or
(b) gross alpha activity or gross beta activity.

Screening for certain radionuclides or for an individual radionuclide
2. (1) Where screening of the water is carried out for certain radionuclides or for an individual radionuclide, the enforcing authority must carry out an analysis of additional radionuclides if, in relation to any supply referred to in paragraph 1—
(a) one of the activity concentrations of a radionuclide in the second column of the table below exceeds 20% of the corresponding derived concentration in the third column; or
(b) the tritium concentration exceeds the parametric value for tritium.
(2) The enforcing authority must, in deciding which radionuclides require to be measured for each supply, take into account all relevant information about likely sources of radioactivity.

Note 1: This table includes values for the most common natural and artificial radionuclides. These are precise values, calculated for a dose of 0.1 mSv, an annual intake of 730 litres and using the dose coefficients laid down in Table (A) of Annex III to Council Directive 96/29/Euratom laying down basic safety standards for the protection of the health of workers and the general public against the dangers arising from ionizing radiation OJ L 159, 29.6.1996, p. 1., as amended by Corrigendum (OJ L 314, 4.12.1996, p. 20). . Derived concentrations for other radionuclides may be calculated on the same basis.			
Note 2: This allows only for the radiological properties of uranium, not for its chemical toxicity.			

Screening for gross alpha activity and gross beta activity
3. (1) The enforcing authority may use screening strategies for gross alpha activity and gross beta activity (or, where appropriate, residual beta activity after subtraction of the potassium-40 activity) to monitor the water for indicative dose.
(2) Subject to sub-paragraph (3), screening levels must be set at—
(a) 0.1 Bq/l for gross alpha activity; and
(b) 1.0 Bq/l for gross beta activity.
(3) The enforcing authority may set alternative levels to those specified in sub-paragraph (2) if it can demonstrate that these will ensure that an indicative dose of 0.1 mSv is not exceeded.
(4) If the gross alpha activity is less than 0.1 Bq/l and the gross beta activity is less than 1.0 Bq/l, the enforcing authority may assume that the indicative dose is less than 0.1 mSv.
(5) Where sub-paragraph (4) applies, the enforcing authority is not required to carry out a radiological investigation unless it is aware—
(a) that specific radionuclides are present in the water; and
(b) that these are liable to cause an indicate dose in excess of 0.1 mSv.
(6) If the gross alpha activity exceeds 0.1 Bq/l or the gross beta activity exceeds 1.0 Bq/l, the enforcing authority must carry out an analysis for specific radionuclides.
(7) The enforcing authority must, in deciding which radionuclides require to be measured for the purposes of sub-paragraph (6), take into account all relevant information about likely sources of radioactivity.
(8) If elevated levels of tritium are detected in a sample, the enforcing authority must also measure the gross alpha activity and gross beta activity in that sample.

Calculation of the indicative dose
4. (1) The indicative dose must be calculated from—
(a) the measured radionuclide concentrations and the dose coefficients laid down in Table (A) of Annex III to Council Directive 96/29/Euratom laying down basic safety standards for the protection of the health of workers and the general public against the dangers arising from ionizing radiation; or
(b) more recent information recognised by the Scottish Ministers,
on the basis of an annual intake of water of 730 litres for adults.
(2) Where the following formula is satisfied, the enforcing authority may assume that the indicative dose is less than 0.1 mSv and that no further investigation is required:—
∑i=lnCi  (obs)Ci (der)) ≤1
where—
“Ci (obs)” refers to the observed concentration of radionuclide “i”;
“Ci (der)” refers to derived concentration of radionuclide “i”; and
“n” refers to the number of radionuclides detected.

SCHEDULE 4 METHODS OF ANALYSIS

PART B Chemical and indicator parameters
1. (1) Subject to paragraph 3, for a parameter in Table 1, the method of analysis used must, as a minimum, be capable of measuring concentrations equal to the parametric value for the parameter with—
(a) a limit of quantification of 30 % or less of the parametric value; and
(b) an uncertainty of measurement as specified in Table 1.
(2) The result of the analysis for a parameter in Table B or Table C must be expressed using at least the same number of significant figures as the parametric value for the parameter in the table.
2. The uncertainty of measurement specified in Table 1 must not be used as an additional tolerance to the parametric values.
3. Until 31st December 2019, the enforcing authority may, for a parameter in Table 2, use the corresponding ‘trueness’, ‘precision’ and ‘limit of detection’ in that table as an alternative set of performance characteristics (instead of using the limit of quantification and the uncertainty of measurement referred to in paragraph 1(1)).

Notes to Table 1 and Table 2
Note 1: Uncertainty of measurement is a non-negative parameter characterising the dispersion of the quantity values being attributed to a measurand, based on the information used. The performance criterion for measurement uncertainty (k = 2) is the percentage of the parametric value stated in the table or better. Measurement uncertainty must be estimated at the level of the parametric value, unless otherwise specified.
Note 2: Trueness is a measure of systematic error, i.e. the difference between the mean value of the large number of repeated measurements and the true value. Further specifications are those set out in international standard ISO 5725 entitled “Accuracy (trueness and precision) of measurement methods and results”.
This standard has been approved by the International Organization for Standardization (ISO). Under reference BS ISO 5725-1 to BS ISO 5725-6, these are published as UK standards by the British Standards Institution.
Note 3: Precision is a measure of random error and is usually expressed as the standard deviation (within and between batches) of the spread of results from the mean. Acceptable precision is twice the relative standard deviation. This term is further specified in international standard ISO 5725 entitled partly “Accuracy (trueness and precision) of measurement methods and results”.
Note 4: Limit of detection is either three times the standard deviation within a batch of a natural sample containing a low concentration of the parameter, or five times the standard deviation of a blank sample (within a batch).
Note 5: If the value of uncertainty of measurement cannot be met, the best available technique should be selected (up to 60 %).
Note 6: The method determines total cyanide in all forms.
Note 7: Values for trueness, precision and uncertainty of measurement are expressed in pH units.
Note 8: Reference method European standard EN ISO 8467:1995 entitled “Water quality - Determination of permanganate index (ISO 8467:1993)”.
This standard was approved by the European Committee for Standardization (CEN) on 3rd November 1994. Under reference EN ISO 8467:1995, it is published as a UK standard by the British Standards Institution (ISBN 0 580 23435 5).
Note 9: The performance characteristics for individual pesticides are given as an indication. Values for the uncertainty of measurement as low as 30 % can be achieved for several pesticides, higher values up to 80 % may be allowed for a number of pesticides.
Note 10: The performance characteristics apply to individual substances, specified at 25 % of the parametric value in Table B.
Note 11: The performance characteristics apply to individual substances, specified at 50 % of the parametric value in Table B.
Note 12: The uncertainty of measurement should be estimated at the level of 3 mg/l of the total organic carbon in accordance with European standard EN 1484:1997 entitled “Water analysis - Guidelines for the determination of total organic carbon and dissolved organic carbon”.
This standard was approved by the European Committee for Standardization (CEN) on 6th April 1997. Under reference BS EN 1484:1997, it is published as a UK standard by the British Standards Institution (ISBN 0 580 28372 0).

PART C Indicative dose
For each parameter in Table 3, the method of analysis used must be capable of measuring activity concentrations with at least the limit of detection specified for that parameter in the second column of that table.

Notes to Table 3
Note 1: The limit of detection must be calculated in accordance with the international standard ISO 11929:2010 entitled “Determination of the characteristic limits (decision threshold, detection limit and limits of the confidence interval) for measurements of ionising radiation - Fundamentals and application”, with probabilities of errors of 1st and 2nd kind of 0.05 each.
This standard has been approved by the International Organization for Standardization (ISO). Under reference BS ISO 11929:2010, it is published as a UK standard by the British Standards Institution (ISBN 978 0 580 59044 3).
Note 2: Measurement uncertainties must be calculated and reported as complete standard uncertainties, or as expanded standard uncertainties with an expansion factor of 1.96, in accordance with international standard ISO/IEC Guide 98-3:2008 entitled “Guide to the expression of uncertainty in measurement”.
This standard has been approved by the International Organization for Standardization (ISO). Under reference ISO/IEC Guide 98-3:2008 Ed 1, it is published as a UK standard by the British Standards Institution.
Note 3: The limit of detection for tritium and for radon is 10% of the corresponding parametric value for the parameter.
Note 4: The limit of detection for gross alpha activity and gross beta activities is 40% of the screening values of 0.1 Bq/l and 1.0 Bq/l respectively.
Note 5: This limit of detection applies only to initial screening for indicative dose for a new water source. If initial checking indicates that it is unlikely that Ra-228 exceeds 20% of the derived concentration, the limit of detection may be increased to 0.08 Bq/l for routine Ra-228 nuclide specific measurements, until a subsequent re-check is required.
