Concentrations of Per- and Polyfluorinated Substances (PFAS), Pesticides, and Pharmaceuticals in Groundwater in Suffolk County, New York, 2021 to 2023

August 6, 2026

This U.S. Geological Survey (USGS) data release contains groundwater quality data for twelve wells in Suffolk County, New York and associated quality assurance results. Samples were collected between 2021 and 2023 and analyzed for per- and polyfluoroalkyl substances (PFAS), pesticides, and pharmaceuticals. Measurements of pH, specific conductance, dissolved oxygen, water temperature and turbidity were recorded at the time of sample collection. Samples collected for quality assurance and quality control (QAQC) include sequential replicates, field blanks, equipment blanks, source solution blanks, and laboratory-control samples. Laboratory-control samples for PFAS analysis included method blanks, isotope dilution standard recoveries, and spikes recoveries.
