EcoWatch - New research has found that 18 percent of private wells sampled in Pennsylvania exceed the maximum contaminant levels for per- and poly-fluoroalkyl substances (PFAS) in drinking water set by the United States Environmental Protection Agency.
Of the wells sampled, 65 percent had detectable levels of PFAS, and almost half contained several of the chemical compounds.
Researchers from Pennsylvania State University (Penn State) conducted a three-year study with data provided by citizen scientists on the levels of PFAS “forever chemicals” in 167 private wells in the state, a press release from Penn State said.
“Due to limited regulation of private wells, individuals who rely on wells as a potable water supply frequently face significant challenges in ensuring safe drinking water. Widespread occurrences of per- and poly-fluoroalkyl substances (PFAS) in groundwater increase these challenges and pose additional threats to public health,” the authors of the study wrote.
