| Description | Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic fluorinated compounds with a wide variety of physical and chemical properties. PFAS have been manufactured since the 1950s for many consumer and industrial uses. Washington State identified PFAS as priority toxic chemicals due to their persistence in the environment, ability to accumulate in organisms, and toxic effects on wildlife and humans. PFAS have been detected in numerous water bodies, fish, and municipal drinking water sources throughout the state. As the regulatory framework for PFAS rapidly evolves, additional sampling will continue to identify a growing number of areas affected by PFAS contamination throughout Washington State. In many locations, the source and extent of PFAS contamination are unknown, and affected areas are often identified by sampling drinking water aquifers. The need for additional PFAS assessments to help identify sources, further define the extent of contamination, and prioritize areas that require further investigation is growing. This Programmatic Quality Assurance Project Plan (QAPP) outlines common objectives for conducting PFAS assessments in areas of known or suspected releases and the necessary procedures to achieve those objectives. This QAPP details study design, measurement and data quality objectives, quality control, field and laboratory, and data management procedures for implementation of the study. The purpose of this QAPP is to allow for timely PFAS investigations to be conducted. For individual site-specific projects, QAPP addendums or scope-of-work memos will provide additional background, a description of the study area, or any additional sampling methods not included in this QAPP. The PFAS assessments are intended to be preliminary. If a more extensive investigation is warranted after the assessment, additional sampling will be recommended in the data summary report. |
