Over the past decade, a diversity of emerging contaminants has been identified in waters around the globe. Of particular interest are pharmaceuticals and personal care products (PPCPs) and potential endocrine disrupting compounds (EDCs), both of which are generally detected in extremely low (sub-µg/L) concentrations in water. Despite these low levels, public, scientific, and regulatory communities have shown increasing interest and concern about the potential occurrence of these compounds in drinking water and their potential health effects. The vast majority of these compounds are not regulated, and developing toxicity criteria can be time consuming and resource intensive. The project reviews methodologies for developing screening level human health risk-based criteria for PPCPs and EDCs potentially present in water intended for indirect potable reuse and develop decision criteria.
