Cardno ChemRisk publishes evaluation of Perfluorooctanoic acid (PFOA) drinking water guidelines

Cardno ChemRisk scientists, Lindsey Garnick, Andrey Massarsky, PhD, Claire M. Hamaji, MPH, Paul Scott, QEP, and Andrew Monnot, PhD recently published an evaluation of current federal and state PFOA drinking water guidelines. Specifically, the analysis evaluated the basis of the health-based guidelines to determine if the methodology utilized by the U.S. Environmental Protection Agency and state agencies accurately captured the magnitude of background exposure to the U.S. population.

As part of the evaluation, our scientists also evaluated the contribution of PFOA in drinking water to the systemic PFOA body burden of the general population using an available biokinetic model. As detailed in the publication, determining the relative significance of the various exposure pathways to the general population will be necessary to understand the drivers of temporal differences in serum PFOA historically measured in various populations as well as for anticipating risks associated with future exposures.

Our scientists have also provided technical support regarding exposure and the potential health effects of various PFAS compounds currently used in place of PFOA by the electronics industry and those identified in personal care and cosmetic products.
