(2) A water undertaker shall–
(a) before it supplies water from a source mentioned in paragraph (1)(a); and
(b) as soon as is reasonably practicable after it has begun to supply water from a source mentioned in paragraph (1)(b),
take in accordance with paragraph (3) such samples of that water as will enable it to establish–

(ii) the treatment necessary to ensure that section 52(1) is complied with in relation to the supply of that water.
(3) Samples shall be taken–
(a) in the case of a source mentioned in paragraph (1)(a), in respect of–

(ii) any other element, organism or substance which, in the opinion of the undertaker, may cause the supply to contravene section 52(1); or
(b) in the case of a source mentioned in paragraph (1)(b), in respect of–
(i) the parameters listed in Table C;
(ii) any parameter by reference to which an assessment may be made of the balance of ions within the water; and
