Lab accreditation assessors trained on PFAS measurement methods during 3-day workshop

Assessors who accredit environmental laboratories in California received training on how to measure per- and polyfluoroalkyl substances (PFAS) in drinking water and environmental matrices during a three-day workshop co-presented by SCCWRP in June – part of an ongoing series of statewide trainings to enhance assessors’ proficiency and expertise.

About 12 accreditors from California’s Environmental Laboratory Accreditation Program (ELAP), along with third-party assessors and State Water Board staff, attended the workshop, which included live demonstrations in SCCWRP’s laboratories. ELAP accredits all public and private laboratories that produce environmental data that get used in State decision-making processes.

The workshop marked the first training opportunity for ELAP assessors following the EPA’s spring 2024 decision requiring drinking water agencies to limit levels of certain types of PFAS in drinking water.

SCCWRP kicked off the ongoing ELAP assessor training series in fall 2023 with a three-day workshop on a suite of commonly used fish bioassay toxicity tests.
