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.\nSamples were collected from temporary push point samplers (manufactured by MHE Inc.) installed 20 to 60 centimeters below the cove bottom sediment.\nAny use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.\nREFERENCES:\nShoemaker, J., and Tettenhorst.
