Field data and Per- and Polyfluoroalkyl Substances (PFAS) analytical results for shallow groundwater samples from Pocasset, Hen Cove, Massachusetts, October 2022

On October 12, 2022, the U.S. Geological Survey (USGS) collected 13 shallow groundwater samples and two quality-control samples for analysis of Per- and Polyfluoroalkyl Substances (PFAS). Samples were collected in Hen Cove, Pocasset, Massachusetts by using USGS water-quality sampling protocols (Shoemaker and Tettenhorst, 2020). Groundwater environmental and quality control samples were analyzed at SGS (Orlando, FL) using EPA method 537.1m. Samples were collected from temporary push point samplers (manufactured by MHE Inc.) installed 20 to 60 centimeters below the cove bottom sediment. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. REFERENCES: Shoemaker, J., and Tettenhorst.
