Groundwater Study and Resources

Overview
In 2013, the County of Lycoming received a $250,000 grant from the PA Department of Community and Economic Development (DCED) through the Act 13 Marcellus Shale Legacy Fund to conduct a county-wide groundwater sampling program to help understand the quality of groundwater in privately owned wells within the County.
As a steward of the health and well-being of our residents, businesses and communities, Lycoming County has a vested interest in our water resources. While surface waters across the county have been studied and monitored by PA Department of Environmental Protection (DEP), groundwater presents a gap in our collective understanding. This study will provide information on the current conditions of our groundwater and is an opportunity to understand what is native to our source water in order to assess the impact of agricultural, mining and other land-use practices on our groundwater.
As part of this study, 75 randomly selected wells were sampled throughout the county. The site selection process included voluntary participation by residents. The study analyzed a comprehensive list of water quality parameters for each well, including substances such as minerals, gasses, and bacteria.
The county’s partners in this project include the U.S. Geological Survey (USGS), Pennsylvania Department of Environmental Protection, Geisinger Health System, the North Central Source Water Protection Alliance, and Susquehanna Health, and West Branch Regional Authority.
The final report is available on the U.S. Geological Survey's (USGS) website:
