Risk Assessment Study of PPCPs in Recycled Water to Support Public Review: Report and Toolkit

To date, discussions of human health risk during nonpotable water reuse project reviews have frequently focused on the presence of residual chemicals in highly technical terms. However, the actual effects of these chemicals on human health, if one considers likely exposure pathways and concentrations, have largely been subject to speculation in the absence of empirical data, raising concerns with the public and hindering acceptance of these projects. The project provides quantitative human health risk assessment results for a small group of selected pharmaceuticals and personal care products (PPCPs) in recycled water for a representative set of nonpotable use cases and to develop a message delivery effort to present the results to the general public.
