Distribution System Water Quality and Treatment Residuals: Arsenic and Other Contaminants

Triantafyllidou, S. AND D. Lytle. Distribution System Water Quality and Treatment Residuals: Arsenic and Other Contaminants. 17th Annual EPA Drinking Water Workshop (Virtual), Virtual, Virtual, August 31 - September 03, 2020.

Impact/Purpose:

The US EPA’s arsenic demonstration program evaluated arsenic removal technologies at 50 small drinking water systems across the US in 2004-2010. Among many considerations were the treated drinking water quality and the type/quantity of treatment residuals that needed disposal. Retrospective data analysis identified 3 patterns of arsenic levels at the tap after arsenic treatment of the source well water, and synthesized residual data from a variety of arsenic treatment methods. The wealth of information from the US EPA’s arsenic demonstration program advances our understanding of arsenic levels at the tap after treatment and can help guide arsenic treatment selection and residuals’ management.
