Educating assessors on a new laboratory method

Assessors who accredit environmental laboratories in California received training on a new statewide method for monitoring up to 140 pesticides simultaneously during a three-day workshop co-presented by SCCWRP in October. About 20 accreditors from California’s Environmental Laboratory Accreditation Program (ELAP), along with third-party assessors, attended the workshop, which included presentations and live demonstrations in SCCWRP’s laboratories on how to use the method to screen and analyze field-collected samples for pesticides.

The workshop is part of a series of SCCWRP-led trainings for ELAP assessors that began in 2023. Past trainings have focused on a suite of commonly used fish bioassay toxicity tests, methods for measuring PFAS in drinking water and environmental matrices, the Ceriodaphnia dubia toxicity test, and methods for measuring harmful algal bloom (HAB) toxins.
