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, scrubland, grassland, herbaceous, wetlands, or barren land. Sampling sites were located at the closest point to the random location identified, where access and permission were available. To limit the potential for sampling results to be influenced by local releases of PFAS, a 500-meter buffer around parcels associated with known...

A total of 15 sites were chosen based on the results of sampling efforts published in Santangelo and others(2022). Sites with relatively high concentrations of PFAS observed during the first study were selected for resampling to better understand the range of concentrations of PFAS in the area. At each of the 15 sites, soil samples were collected as near to the original site as possible (site A), and a second set of soil samples were collected at a secondary location (site B) 50 to 600 feet away from the original location for a total...

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 former Brentwood Fire Training Area, PFAS-containing aqueous film-forming foams were applied as part of regular fire training exercises. At each site, soil samples were collected in a gridded pattern over the site. Soil horizons within the sampling intervals were described using the National Soil Survey Center Natural Resources...
