Field-scale investigation of per- and polyfluoroalkyl substances (PFAS) leaching from shallow soils to groundwater at two sites in New Hampshire, 2021-2022

Per- and polyfluoroalkyl substances (PFAS) and related chemical and physical data are presented from shallow soil and groundwater at two sites in New Hampshire. The two sites, the former Brentwood Fire Training Area and White Farm, were selected because materials known to contain PFAS were used at each site. White Farm is an active farm where biosolids have been applied for several years. At the f

Statewide survey of shallow soil concentrations of per- and polyfluoroalkyl substances (PFAS) and related chemical and physical data across New Hampshire, 2021

Per- and polyfluoroalkyl substances (PFAS) and related chemical and physical data are presented from 100 shallow soil sampling locations within the State of New Hampshire. Sites were randomly determined through an equal-area grid approach (Scott, 1990) targeting undisturbed areas, which included lands classified by the 2016 National Land Cover Database (Dewitz, 2019) as forested, shrubland, scrubl

Data for Occurrence and Sources of Lead in Private Wells, Sturbridge, Massachusetts

This dataset contains water-quality data, quality-control data, and input and output data for geochemical models that support the findings of a study of lead in drinking water in the Sturbridge, Massachusetts, study area. These data include major and trace element data for unfiltered and filtered (dissolved) samples collected from both taps and well heads at private well sites, and quality-control

Occurrence and sources of lead in private wells, Sturbridge, Massachusetts

Lead (Pb) occurrence and sources and aqueous geochemistry were assessed in private wellhead and tap water at a targeted area of concern for possible exceedances and at a control area in the same geologic formation, and in wells at a nearby landfill in south-central Massachusetts (MA). Total Pb concentrations were below the U.S. Environmental Protection Agency (USEPA) Action Level of 15 μg/L in all

Per- and polyfluoroalkyl substances (PFAS) in New Hampshire soils and biosolids

The U.S. Geological Survey, in cooperation with the New Hampshire Department of Environmental Services, is undertaking a study on per- and polyfluoroalkyl substances (PFAS) in soils and biosolids. The study will characterize PFAS concentrations in shallow soil and selected biosolids throughout the State of New Hampshire, conduct laboratory experiments to improve understanding of how mobile PFAS ar
