Pesticides in Pennsylvania Groundwaters

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...

Groundwater Quality of Domestic Supply Wells in Pennsylvania

Most rural residents in Pennsylvania use groundwater from domestic supply wells for drinking, cleaning and other purposes. Some groundwater samples have been analyzed for private purposes, but those results generally are not readily available to the public. Many of the publicly available water-quality samples from rural areas were collected more than 30 years ago. Quality-assured groundwater...

Map of potential radon exposure from groundwater and indoor air in Pennsylvania

Evaluation of Radon in Groundwater and Indoor Air in Pennsylvania

Existing groundwater and indoor air radon-222, hereafter referred to as "radon", concentrations were aggregated and evaluated for 16 geologic units throughout the state of Pennsylvania to provide a better understanding of potential human exposure to radon.

Volatile organic compounds in groundwater used for public supply across the United States: Occurrence, explanatory factors, and human-health context

This systematic assessment of occurrence for 85 volatile organic compounds (VOCs) in raw (untreated) groundwater used for public supply across the United States (U.S.), which includes 43 compounds not previously monitored by national studies, relates VOC occurrence to explanatory factors and assesses VOC detections in a human-health context. Samples were collected in 2013 through 2019 from 1537 pu

Characterization of ambient groundwater quality within a statewide, fixed-station monitoring network in Pennsylvania, 2015–19

Pennsylvania leads the Nation in the number of individuals that use groundwater for private domestic water supply; more than 3 million rural and suburban Pennsylvania residents rely on private domestic supplies for drinking water. These supplies are not regulated nor routinely monitored; thus relevant groundwater-quality information is not widely available. The U.S. Geological Survey (USGS), in co
