Risk assessment of water supplies

10.—(1) An enforcing authority must carry out a risk assessment in relation to water introduced into, and supplied through and from, each private water supply system to premises in its area so as to establish if there is any risk that the water could pose a potential danger to human health.

(ii) water at each point of compliance meets the water quality standards; and

(b) assess available information on the quality of water supplied to establish whether—

(i) the water quality standards are being met; and

(ii) the parametric values in Table C are not being exceeded; and

(c) identify the most appropriate means of mitigating any risk to human health.

(4) The assessment—

(a) must be carried out in accordance with a method which is approved by the Drinking Water Quality Regulator for Scotland;

(c) must take into account the results of monitoring carried out—

(i) under these Regulations; and

(ii) under section 8 (monitoring) of the Water Environment and Water Services (Scotland) Act 2003 in respect of bodies of water identified under section 6 of that Act (bodies of water used for the abstraction of drinking water).

(5) For each assessment, the enforcing authority must ensure that—

(a) the following is made available to any person who requests it (“the information”):—

(i) information showing that a risk assessment has been carried out; and

(ii) a summary of the results of the risk assessment; and
