Expired Drinking Water Laboratory Accreditation


Background

Section 64415(a) of the California Code of Regulations (CCR) requires that analyses pursuant to Chapter 15 “Domestic Water Quality and Monitoring Regulations” be performed by environmental laboratories accredited by the Environmental Laboratory Accreditation Program (ELAP). To maintain accreditation, a laboratory must comply with the application requirements as cited in the Environmental Laboratory Accreditation Act Sections 100825-100920 and California Code of Regulations, Title 22, Division 4, Chapter 19.  ELAP accreditation is valid for only two years. If a laboratory does not apply for renewal at least 90 days prior to the expiration of its current accreditation, the certificate may expire and the laboratory will no longer be accredited (CCR §64805(d)). Laboratories must also meet regulatory requirements imlemented by ELAP to remain accredited for drinking water analyses. ELAP may rescind accreditation if a laboratory is unable to meet these requirements.

What is a water system’s responsibility?

It is a water system’s responsibility to ensure its laboratory is accredited to perform the analyses for its monitoring requirements. Failure to have compliance samples analyzed by an ELAP-accredited laboratory could result in a monitoring violation requiring public notification and a requirement to resample (California Code of Regulations Section 64415(a)). Note that use of an unaccredited laboratory for services other than drinking water quality compliance analyses is not affected by loss of accreditation.

Below is a list of laboratories who are no longer accredited to perform water analyses.
