PART 4 — Action in The Event of Failure

Provision of information

15

Procedure following investigation

17

• (1) Once the Department has established the cause of the water being unwholesome in a private water supply monitored under these regulations, it must act in accordance with paragraphs (2) to (4).

• (2) If the cause of the water not being wholesome is attributable to the domestic distribution system within a private dwelling, the Department must promptly offer advice to the consumers on measures necessary for the protection of health.

• (c) ensure the obligations in paragraph 1(1)(a) of Schedule 2 have been met;

• (d) verify that the requirements of regulation 5(a) have been met.

• (3) In accordance with paragraph (1) and subject to paragraphs (4) and (5) the sampling frequency for a parameter in this Schedule including any other micro-organism, parasite or substance included in the Group A or Group B parameters (except radon, tritium and indicative dose), may be reduced or the parameter removed (except radon, tritium and indicative dose) from the list of parameters to be monitored under this Schedule provided that the following conditions are met—

PART 3 — Monitoring for Indicative Dose and Analytical Performance Characteristics

Monitoring for Compliance with the ID

6

Screening strategy for gross alpha activity and gross beta activity may be used to monitor for the parametric indicator value for indicative dose.

Calculation of the ID

7

The ID must be calculated from the measured radionuclide concentrations and the dose coefficients referred to as “standard values and relationships” in Article 13, and recommended for the estimation of doses from internal exposure in the definition of “standard values and relationships” in Article 4(96), of the Council Directive 2013/59/Euratom laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation or more recent information recognised by the Department, on the basis of the annual intake of water (730l for adults).
