RE: Peer Review Requested on OEHHA Proposed Perchlorate Public Health Goal

Following detailed comments submitted in February, the Perchlorate Study Group (PSG) and the Partnership for Sound Science in Environmental Policy (PSSEP) have asked California’s Office of Environmental Health Hazard Assessment (OEHHA) to submit its risk assessment for the proposed perchlorate Public Health Goal to external scientific peer review.

A joint PSG/PSSEP letter highlighted significant concerns with OEHHA’s proposal, including “serious scientific flaws” and “misplaced assumptions” which demonstrate OEHHA’s risk assessment was not based on the best available science.

OEHHA must submit its draft risk assessment for peer review before taking any further action on the public health goal, pursuant to California Law [Health and Safety Code Section 116365(c)(3)(D)].

Research on perchlorate spans six decades, dating back to its use as a medicine, making it one of the most understood compounds regulators are examining today. This research has definitively concluded that low levels of perchlorate detected in the environment do not pose a public health concern.
