AWWA ACE65462

This power point presentation begins by presenting concerns about environmental pollutants in water, and what types of contaminants are regulated, and what types are not. Elements for developing traditional toxicity criteria are provided, along with risk assessment and an alternative approach called Mechanism of Action (MOA). An AWWARF study titled, "Toxicological Relevance of Endocrine Disruptors and Pharmaceuticals in Drinking Water" is presented and the presentation outlines topics that include: the project focus on measuring concentrations in water source, and risk assessments of low-level pharmaceutical and endocrine-disrupting chemical (EDC) exposures to inform future directions; Linking Occurrence and Bioassay Data for Risk Assessment; Pharmaceuticals; Selecting Target Pharmaceuticals; Draft Candidate List of Pharmaceuticals; Developing Toxicity Criteria: Preliminary Values; How Many Liters of Water Would You Have to Drink; Endocrine Disrupting Chemicals; Selecting Target EDCs; EDC Levels Measured; and, MultiCriteria Decision Analysis.
