Pennsylvania Groundwater Watch
Pennsylvania Groundwater Watch provides access to groundwater level data from 108 sites in the USGS Active Groundwater Level Network for Adams, Chester, Montgomery, Philadelphia, and Pike Counties.
Pennsylvania Groundwater Quality Monitoring Network Data Exploration Tool
USGS Pennsylvania Water Science Center, in cooperation with the Pennsylvania Department of Environmental Protection, samples 28 wells biannually to monitor ambient groundwater quality conditions in a variety of settings throughout Pennsylvania. The most recent results for selected constituents can be accessed through the Groundwater Quality Monitoring Network Data Exploration Tool.
Pennsylvania Drought Condition Monitoring
The Pennsylvania Drought Condition Monitoring Application shows the current drought status for each county and hydrologic conditions for precipitation, streamflow, groundwater levels, and Palmer Drought-Severity Index used by PaDEP for drought monitoring.

Pennsylvania Groundwater Quality Monitoring Network
USGS Pennsylvania Water Science Center, in cooperation with the Pennsylvania Department of Environmental Protection, samples 28 wells biannually to monitor ambient groundwater quality conditions throughout Pennsylvania.Regional Synthesis of Groundwater Quality in Domestic Supply Wells in Northeast and North Central Pennsylvania
USGS synthesized groundwater quality measurements in wells to characterize regional chemical characteristics of aquifers used for domestic supply in northeast and north central Pennsylvania.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...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. - Publications
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 puAuthorsLaura M. Bexfield, Kenneth Belitz, Miranda S. Fram, Bruce D. LindseyCharacterization 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 coAuthorsMatthew D.
