Pennsylvania Water Science Center
About
In Pennsylvania, the USGS's water-resources roots date back to the late 1800s, with the initiation of streamflow gaging on the Delaware and Susquehanna Rivers. Today we work in cooperation with numerous federal, state, and local agencies to collect scientific data and conduct scientific studies of the source, quantity, quality, ecology, and use of Pennsylvania's water resources.
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 is done in partnership with state and local entities.
