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.
Delaware River Basin
In Pennsylvania, the USGS's water-resources roots date back to the late 1800's, with the initiation of streamflow gaging on the Delaware and Susquehanna Rivers and assessments of groundwater resources near Philadelphia. The USGS Pennsylvania Water Science Center continues to provide scientific information about the water resources of the Delaware River Basin, in cooperation with regional and local...
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...
Shale Gas and Water Resources in Pennsylvania
The Pennsylvania Water Science Center and other USGS scientists are studying water availability, use, quality, and ecology associated with development of shale-gas energy resources in Pennsylvania.
Fractured-Rock Test Holes in Areas of Marcellus Shale Gas Development, Pennsylvania
USGS and Pennsylvania Geological Survey analyzed rock cuttings, geophysical logs, water quality, water-bearing zones, gas-isotope, and other data from deep test holes drilled in fractured bedrock in north-central Pennsylvania. The results of this study helped to quantify the depth and character of fresh and saline groundwater in areas of shale-gas exploration and development.
