# The Public Water Supplies (Scotland) Regulations 2014, Paragraph 2


Based on the results of a risk assessment, the list of parameters in Part B of this schedule (including any micro-organism, parasite or substance referred to in paragraph 2(1)(b) of that Part), must be extended and/or the minimum sampling frequencies under that Part increased if—
(a) the list of parameters or frequencies required to be monitored under that Part B is not sufficient to fulfil the obligations imposed by regulation 5(1), (3) and (4);
(b) additional monitoring is required by regulation 5(2); ...
(c) this is necessary to verify the matters in paragraph 1(a) of Part A of this schedule,
(d) a risk assessment has established that raw water—
(i) in the catchment area used to abstract water for human consumption purposes, or
(ii) as a result of abstraction through the public water supply system,
contains a parameter at a concentration or value which would (whether in conjunction with another parameter in the water or otherwise) constitute a potential danger to human health, or
(e) a risk assessment has identified extension of the list of parameters and/or increase of the minimum sampling frequencies as the most appropriate means of mitigating a risk to human health
