PA PFAS Concentration Graphic

Detailed Description

A graphic depicting the distribution of total PFAS concentrations across the PADEP Surface Water Quality Network (WQN). Total PFAS concentrations in individual samples ranged from non-detect (depicted as zero on this scale) to 113 nanograms per liter (ng/L). Total PFAS values were calculated by summing the concentrations of each of 33 tested PFAS, plus any oxidizable PFAS precursors present in the sample.
