Speth, T., U.S. EPA National Risk Management Research Laboratory webinar, 40 slides, 2019

This presentation focused on treating contaminants of emerging concern with an emphasis on determining cost-effective solutions for small systems. PFAS, cyanotoxins, and perchlorate were used to show how contaminant properties influence treatment effectiveness, operational complexity, cost, and residual stream handling and to discuss novel technologies. Each technology and contaminant included a discussion on how to avoid unintended consequences, such as increased water corrosivity or residual handling problems. Available EPA tools and expertise were highlighted. https://www.epa.gov/sites/production/files/2019-03/documents/2019-03-20_cec_treatment_state_webinar.pdf
