Council Directive 98/83/ECDangos y teitl llawn

TABLE A Parameters to be analysed U.K.

1. Check monitoring U.K.

The purpose of check monitoring is regularly to provide information on the organoleptic and microbiological quality of the water supplied for human consumption as well as information on the effectiveness of drinking-water treatment (particularly of disinfection) where it is used, in order to determine whether or not water intended for human consumption complies with the relevant parametric values laid down in this Directive.

The following parameters must be subject to check monitoring. Member States may add other parameters to this list if they deem it appropriate.

• Aluminium (Note 1)

• Ammonium

• Colour

• Conductivity

• Clostridium perfringens (including spores) (Note 2)

• Escherichia coli (E. coli)

• Hydrogen ion concentration

• Iron (Note 1)

• Nitrite (Note 3)

• Odour

• Pseudomonas aeruginosa (Note 4)

• Taste

• Colony count 22 °C and 37 °C (Note 4)

• Coliform bacteria

• Turbidity

a In all other cases, the parameters are in the list for audit monitoring.
Note 1:	Necessary only when used as flocculanta.
Note 2:	Necessary only if the water originates from or is influenced by surface watera.
Note 3:	Necessary only when chloramination is used as a disinfectanta.
Note 4:	Necessary only in the case of water offered for sale in bottles or containers.

[F1 2. Audit monitoring U.K.

The purpose of audit monitoring is to provide the information necessary to determine whether or not all of the Directive’s parametric values are being complied with. All parameters set in accordance with Article 5(2) and (3) must be subject to audit monitoring unless it can be established by the competent authorities, for a period of time to be determined by them, that a parameter is not likely to be present in a given supply in concentrations which could lead to the risk of a breach of the relevant parametric value. This point does not apply to the parameters for radioactivity, which, subject to Notes 8, 9 and 10 in Annex I, Part C, will be monitored in accordance with monitoring requirements adopted by the Commission. Those measures, designed to amend non-essential elements of this Directive by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 12(3).]
