Regional Synthesis of Groundwater Quality in Domestic Supply Wells in Northeast and North Central Pennsylvania Completed
New Publication
Factors affecting groundwater quality used for domestic supply in Marcellus Shale region of North-Central and North-East Pennsylvania, USA
USGS synthesized groundwater quality measurements in wells to characterize regional chemical characteristics of aquifers used for domestic supply in northeast and north central Pennsylvania.
Independent county-wide groundwater quality investigations were completed during 2011-2017 by the USGS for seven counties in the northern tier of Pennsylvania where there is ongoing, or potential for, unconventional shale-gas development. The studies used consistent data collection and reporting procedures. County-level reports were published by the USGS that describe quality of water samples from home-owner wells in relation to human health and potential environmental factors affecting the groundwater composition.
The objective of this project was to complete a regional synthesis of groundwater chemical characteristics for aquifers used for domestic supply in northeast and north central Pennsylvania. Available hydrochemical data from 436 domestic wells that were sampled during 2011-2017 and reported by the USGS for seven counties in the northern tier of Pennsylvania as part of county-wide assessments were summarized and evaluated in relation to geology, land use, and other environmental factors, such as hydrogeologic setting.

Factors Affecting Groundwater Quality Used for Domestic Supply in Marcellus Shale Region of North-Central and North-East Pennsylvania, USA
Factors affecting groundwater quality used for domestic supply within the Marcellus Shale footprint in north-central and north-east Pennsylvania are identified using a combination of spatial, statistical, and geochemical modeling. Untreated groundwater, sampled during 2011–2017 from 472 domestic wells within the study area, exhibited wide ranges in pH (4.5–9.3), total dissolved solids (TDS, 22–196AuthorsCharles A. Cravotta, Lisa A. Senior, Matthew D. ConlonFilter Total Items: 18Baseline groundwater quality from 34 wells in Wayne County, Pennsylvania, 2011 and 2013
Wayne County, Pennsylvania, is underlain by the Marcellus Shale, which currently (2014) is being developed elsewhere in Pennsylvania for natural gas. All residents of largely rural Wayne County rely on groundwater for water supply, primarily from bedrock aquifers (shales and sandstones).

SlotoBaseline groundwater quality from 20 domestic wells in Sullivan County, Pennsylvania, 2012
Water samples were collected from 20 domestic wells during August and September 2012 and analyzed for 47 constituents and properties, including nutrients, major ions, metals and trace elements, radioactivity, and dissolved gases, including methane and radon-222.

This report provides a November 2010 snapshot of groundwater quality and an analysis of the sources of water to wells at the U.S. Geological Survey (USGS) Northern Appalachian Research Laboratory (NARL) near Wellsboro, Pennsylvania.

Pike County, a 545 square-mile area in northeastern Pennsylvania, has experienced the largest relative population growth of any county in the state from 1990 to 2000 and its population is projected to grow substantially through 2025. This growing population may result in added dependence and stresses on water resources, including the potential to reduce the quantity and degrade the quality of grouAuthorsLisa A.

In January 2001, State oil and gas inspectors noted bubbles of natural gas in well water during a complaint investigation near Tioga Junction, Tioga County, north-central Pa. By 2004, the gas occurrence in ground water and accumulation in homes was a safety concern; inspectors were taking action to plug abandoned gas wells and collect gas samples.
