This data release presents chemical results from investigations of surface-water quality in the Potomac River watershed (encompassing Washington, D.C. and parts of West Virginia, Virginia, Pennsylvania, and Maryland) conducted during low-flow conditions in July through September of 2022 and modeling results that support interpretative products. Water-quality sampling: A sampling campaign was conducted at 32 stream sites throughout the watershed (Table 1). A suite of field parameters and inorganic and organic chemical characteristics at each site were characterized using seven separate analytical methods at five laboratories (Table 2). The water-quality results are presented in Table 3. Analytical methods and laboratories...

These data were collected to understand the occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in the middle Chickahominy River watershed, Virginia. Specifically, this effort was initiated at selected locations in the middle Chickahominy River watershed to: 1. Determine concentrations of PFAS in surface water; 2. Determine concentrations of PFAS in edible portions of fish; 3. Determine concentrations of PFAS in bed sediment; and 4. Quality Assure all data collected in accordance with USGS policies and publicly release those data as a citable USGS Data Series. Description of Available Datasets: These data are available in four Excel (.xlsx) files that contain water-quality and quality-assurance results....
