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

Machine learning models of arsenic in private wells throughout the conterminous United States as a tool for exposure assessment in human health studies
Methanogens and their syntrophic partners dominate zones of enhanced magnetic susceptibility at a petroleum contaminated site
Inclusion of pesticide transformation products is key to estimating pesticide exposures and effects in small U.S. streams
Cyanotoxin mixture models: Relating environmental variables and toxin co-occurrence to human exposure risk
Toxic cyanobacterial blooms, often containing multiple toxins, are a serious public health issue. However, there are no known models that predict a cyanotoxin mixture (anatoxin-a, microcystin, saxitoxin). This paper presents two cyanotoxin mixture models (MIX) and compares them to two microcystin (MC) models from data collected in 2016–2017 from three recurring cyanobacterial bloom locations in Ka
Isolating the AFFF signature in coastal watersheds using oxidizable PFAS precursors and unexplained organofluorine
Water supplies for millions of U.S. individuals exceed maximum contaminant levels for per- and polyfluoroalkyl substances (PFAS). Contemporary and legacy use of aqueous film forming foams (AFFF) is a major contamination source. However, diverse PFAS sources are present within watersheds, making it difficult to isolate their predominant origins. Here we examine PFAS source signatures among six adja
