| Description | Per- and polyfluoroalkyl substances (PFAS) are a group of human-made fluorinated chemicals. There are thousands of PFAS compounds, many of which are known to be persistent, bioaccumulative, and toxic, and many more with unknown properties and health effects. Because of their widespread use in common consumer products and commercial and industrial applications, PFAS are found almost everywhere globally. In Washington, two statewide studies conducted in 2008 and 2016 found detections of PFAS in all 18 waterbodies sampled. The highest levels of PFAS were found in urban and wastewater treatment plant-influenced waterbodies. Given the widespread occurrence of PFAS and the large network of surface waters across the state, there are likely waterbodies with PFAS contamination that remain unidentified, potentially posing a risk to human health and the environment. In this study, the Washington State Department of Ecology (Ecology) will conduct a survey to screen for PFAS in selected freshwater bodies across the state. The main goal of this study is to document and characterize PFAS concentrations in surface waters across Washington, focusing in areas that have little or no PFAS data, and that have potential for PFAS contamination from surrounding land uses. This study proposes collecting surface water samples from 35 freshwater bodies in watersheds characterized by different land uses across Washington during one summer low flow and one spring high flow event. Results from the study will add to our knowledge about PFAS occurrence in Washington and may indicate areas with contamination that might otherwise remain unidentified and unaddressed. |
