The Private Water Supplies (Wales) Regulations 2010 (revoked)

[F1Indicative DoseE+W

3.(1) In relation to the indicative dose (“ID”) parameter in the radioactive substances parameters table, a local authority must carry out monitoring where a source of artificial radioactivity or elevated natural radioactivity is present and it cannot be shown on the basis of other surveillance programmes or investigations, including any risk assessment carried out in accordance with regulation 6, that the level of ID is below the parametric value listed the radioactive substances parameters table.

(2) Where monitoring is required by sub-paragraph (1) in relation to artificial radionuclides—

(a)it must be carried out at the frequencies as set out for audit monitoring in Table 3 in Part 2 of Schedule 2;

(b)it must (in the case of a private water supply falling within the scope of regulation 10(1)) be carried out at least every five years and more frequently if the risk assessment shows this to be necessary.

(3) Where monitoring is required by sub-paragraph (1) in relation to a source of elevated natural radioactivity—

(a)the local authority—

(i)may decide the frequency of monitoring in its area depending on the screening strategy adopted by the authority; and

(ii)must notify the Welsh Ministers in writing of its decision under sub-paragraph (i); and

(b)the frequency of monitoring decided under sub-paragraph (a)(i) may vary from a single check measurement to the frequencies as set out for audit monitoring in Table 3 in Part 2 of Schedule 2.

(4) Where a local authority decides under sub-paragraph (3) that a single check measurement for natural radioactivity is appropriate, the local 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.]
