If the results of an accredited laboratory’s analysis (whether or not the analysis has been requested to comply with subsection (1)) indicate that drinking water does not comply with the drinking water standards or compliance rules, the laboratory must notify the Water Services Authority and the drinking water supplier as soon as practicable after the results are known.
In this subpart, accredited laboratory means a person accredited under section 77 to perform the functions of a laboratory that analyses source water, raw water, and drinking water.
