The USGS Pennsylvania Water Science Center strives to meet the water-information needs of the public we serve.
Our organization aligns around the core functions needed to provide water resources science, information, and data for the Commonwealth of Pennsylvania and its citizens.
The role of the USGS is to provide technically sound and unbiased data and information products that describe the location, quantity, and quality of surface water and groundwater. Much of the work the USGS does pertaining to water resources in Pennsylvania is done in partnership with Commonwealth and local entities.
