Textual Amendments

F1 Sch. 12 inserted (6.4.2018) by The Natural Mineral Water, Spring Water and Bottled Drinking Water (England) (Amendment) Regulations 2018 (S.I. 2018/352), reg. 1(1), Sch. 2

Analysis of sample E+W+S

50.— (1) Each food authority must monitor the concentration or value (as the case may be) of each of the parameters specified in the first column of the table in Section 1 in water in its area to which this Schedule applies by analysing a sample of the water to determine whether—

(a) the concentration of, or value for, the parameter in the sample exceeds the concentration of, or value for, that parameter specified in the second column of the table—

(i) as measured, where relevant, by reference to the unit of measurement specified in the third column of the table, and

(ii) as read, in relation to a parameter specified in the first column of the table for which there is an additional requirement specified in the fourth column of the table, with the provision relating to the need to check the parameter specified in the fourth column of the table, and

(b) in relation to a parameter specified in the first column of the table for which there is an additional requirement specified in the fifth column of the table, the water complies with that additional requirement.

(2) For the purpose of the determination required by sub-paragraph (1), the food authority must analyse the sample—

(a) in the case of Clostridium perfringens, and spores of Clostridium perfringens, using the method of analysis in BS EN ISO 14189:2016 entitled “Water quality — Enumeration of Clostridium perfringens — Method using membrane filtration (ISO 14189:2013)” (ISBN 978 0 580 92184 1), as amended by a corrigendum issued on 31st August 2016;

(b) in the case of coliform bacteria, using the method of analysis in—

(i) BS EN ISO 9308-1:2014+A1:2017 entitled “Water quality — Enumeration of Escherichia coli and coliform bacteria. Part 1: Membrane filtration method for waters with low bacterial background flora (ISO 9308-1:2014)” (ISBN 978 0 580 92379 1) published by the BSI on 31st October 2014, as amended on 28th February 2017, or

(ii) BS EN ISO 9308-2:2014 entitled “Water quality — Enumeration of Escherichia coli and coliform bacteria. Part 2: Most probable number method” (ISBN 978 0 580 84023 4) published by the BSI on 30th November 2013, as amended by a corrigendum issued on 30th June 2014;

(c) in the case of each of the other indicator parameters, using a method of analysis that complies with Section 3.

Clostridium perfringens E+W+S

51.   In a case where a food authority determines that a sample of water contains any Clostridium perfringens, or spores of Clostridium perfringens, the food authority must investigate the water supply to determine whether there is any potential danger to human health arising from the presence in the water of pathogenic microorganisms.

Uncertainty of measurement E+W+S

52.   A food authority must not use the uncertainty of measurement percentage specified in the second column of the table in Section 4 (which is concerned with whether a method of analysis complies with minimum performance characteristics) as an additional tolerance when determining whether the concentration of a parameter specified in the first column of the table in Section 1 in a sample of water exceeds the concentration for that parameter specified in the second column of the table in Section 1.]
