Explanatory note

These Regulations amend the Water Supply (Water Quality) Regulations 2010 (“the 2010 Regulations”) so as to implement Council Directive 2013/51/EURATOM on the protection of the health of the general public with regard to the radioactive substances in water intended for human consumption in relation to water supplied by water undertakers whose areas are wholly or mainly in Wales.

Regulation 3 of these Regulations inserts new regulation 6A (monitoring of radioactive substances) into the 2010 Regulations. New regulation 6A makes provision for new requirements in relation to monitoring for radon, tritium and indicative dose (“the radioactive substances parameters”).

Regulation 5 of these Regulations inserts a new Schedule 2A (radioactive substances parameters) into the 2010 Regulations. The new Schedule 2A sets parametric values for the radioactive substances parameters.

Regulation 7 of these Regulations inserts new Schedule 3A (monitoring of radioactive substances) into the 2010 Regulations which includes further monitoring requirements for the radioactive substances parameters.

Regulation 8 of these Regulations inserts new Schedule 5 (monitoring for indicative dose and analytical performance characteristics) into the 2010 Regulations. The new Schedule 5 makes provision for additional sampling and analysis requirements in relation to the radioactive substances parameters listed in the new Schedule 2A.

Regulations 2, 4 and 6 of these Regulations make consequential amendments in light of the above.

The Welsh Ministers’ Code of Practice on the carrying out of Regulatory Impact Assessments was considered in relation to these Regulations. As a result, it was not considered necessary to carry out a regulatory impact assessment as to the likely costs and benefits of complying with these Regulations.
