AWWA Water Science: Does regulating per- and polyfluoroalkyl substances represent a meaningful opportunity for health risk reduction?
By: Chad Seidel, Katherine Alfredo, Amlan Ghosh US Environmental Protection Agency’s drinking water contaminant regulations must meet a qualitative “meaningful opportunity” threshold in health risk reduction. Using our Relative Health Indicator (RHI) metric, we quantify the ranges of potential health risk reductions that could be achieved from state and federal per- and polyfluoroalkyl substances regulatory levels (proposed or finalized) and compare them with previous regulatory determinations of other contaminants to create a quantifiable, comparable scale of “meaningful opportunity” justifications.
California Drinking Water Needs Assessment 2021-22
The Human Right to Water “HR2W” guides the California Water Board’s mission of functioning and sustainable drinking water systems. To develop the first Statewide Drinking Water Needs Assessment, Council member Chad Seidel and his colleagues worked alongside other water professionals to evaluate the current challenges facing safe and affordable water supply in California.
