On March 20th, 2019, EPA ORD's Tom Speth presented a webinar on treatment technologies for three contaminants of emerging concern (CECs)—PFAS, cyanotoxins, and perchlorate—with an emphasis on determining cost-effective solutions for small systems. Specifically, how contaminant properties influence treatment effectiveness, operational complexity, cost, and residual stream handling was discussed. Also, novel technologies were discussed using anaerobic biofiltration of perchlorate and nitrate as an example, and a demonstration on the impact of system size to capital and operating costs was shown. For each technology and contaminant, how to avoid unintended consequences, such as increased water corrosivity or residual handling problems, was covered.
