# The Private Water Supplies (England) Regulations 2016, Paragraph 5: Variation of monitoring requirements


(1) When monitoring for a Group A or Group B parameter, a local authority may reduce the sampling frequency in respect of any parameter in Group A or Group B other than E. coli provided that—
(a) the results from samples taken in respect of that parameter collected at regular intervals over a period of at least three years are all at less than 60% of the parametric value;
(b) the results of a risk assessment described in regulation 6(l) are considered, and that risk assessment indicates that no factor can be reasonably anticipated to be likely to cause deterioration of the quality of the water;
(c) data collected in the course of discharging its monitoring obligations under this Part are taken into account; and
(d) at least one sample is taken per year.
(2) A local authority may cease to monitor for a Group A or Group B parameter other than E. coli provided that—
(a) the results from samples taken in respect of that parameter collected at regular intervals over a period of at least three years are all at less than 30% of the parametric value;
(b) the results of a risk assessment described in regulation 6(l) are considered, and that risk assessment indicates that no factor can be reasonably anticipated to be likely to cause deterioration of the quality of the water; and
(c) data collected in the course of discharging its monitoring obligations under this Part are taken into account.
(3) A local authority may set a higher frequency for any parameter if it considers it appropriate, taking into account the findings of any risk assessment, and may monitor anything else identified in the risk assessment.
