Findings to help drinking water utilities increase treatment resilience to wildfires.
PORTLAND, Ore., January 17, 2023 — A multi-disciplinary team of utilities, academia, and consultants have convened to develop a study and publish guidance to improve water treatment resilience against the impacts of forest fires.
Critical to water security, forested watersheds provide 75 percent of the world’s accessible freshwater (Food and Agriculture Organization of United Nations 2021) and supply drinking water for more than two-thirds of North American consumers (EPA 2019). The frequency and severity of forest fires have been increasing globally with warming temperatures and shifting precipitation patterns due to climate change. Wildfires can cause costly, long-term water treatment issues that push water treatment processes beyond their design and operational response capabilities.
Such issues include filtration effectiveness, disinfection efficacy, the elevation of disinfection by-product formation, and increased bioavailable phosphorus leading to problematic cyanobacterial/algal blooms.
Led by a principal research team of Lynn Stephens (Brown and Caldwell), Dr. Mac Gifford and Yone Akagi (Portland Water Bureau), and Dr. Monica Emelko (University of Waterloo), Water Research Foundation (WRF) project #5168 is funded by the foundation’s Emerging Opportunities Program and the Portland Water Bureau (PWB).
