  "text": "(1) Paragraph (2) applies where there is a risk (“the prescribed risk”) that water supplied by a relevant supplier would, for the reason mentioned in paragraph (3), after leaving the relevant supplier's pipes—\n(a) contain a concentration of copper in excess of 2 mg/litre; or\n(b) contain a concentration of lead in excess of 10 μg/litre.\n(2) Every water undertaker or supplementary licensee which introduces water into the supply system used by the relevant supplier must, subject to paragraph (4), treat the water in such a way as will, in its opinion, eliminate the prescribed risk or reduce it to a minimum.\n(3) The reason referred to in paragraph (1) is the presence in the water of a concentration of copper or lead which is attributable to the fact that copper or lead is the major component of such a pipe as is mentioned in section 68(3)(a) of the Act, or its associated fittings.\n(4) Paragraph (1) will not require a water undertaker or supplementary licensee to treat water—\n(a) if the treatment is unlikely to achieve a significant reduction in the concentration of copper or lead; or\n(b) if treatment is not reasonably practicable.",
