USGS Documents Sampling Results for Pesticides in Groundwater
New geonarrative, in cooperation with the Pennsylvania Department of Agriculture
USGS annually samples domestic groundwater wells to characterize pesticides, nutrients, and radon in agricultural areas, in cooperation with the Pennsylvania Department of Agriculture. Beginning in 2021, samples for major ions, trace elements, bacteria, and isotopes will also be collected. A subset of wells will be sampled for per- and polyfluoroalkyl substances (PFAS), emerging industrial contaminants in Pennsylvania groundwaters.
This project began in 2003 to further the understanding of pesticide concentrations in different hydrogeologic settings. Pesticides sampling by USGS in Pennsylvania began in carbonate aquifers in the southeastern part of the state in the 1980s. Assessments of pesticides in groundwater were conducted in the Potomac, Delaware, Lower Susquehanna, Allegheny, and Monongahela River basins during the first round of the National Water Quality Assessment (NAWQA ) studies. Findings are summarized in a Previous Studies Archive.
