New Interactive Map of Chester County Waterways

Chester County Water Quality Conditions: New Interactive Map of Monitoring Sites Published

We invite you to visit the Chester County Water Resources Authority’s new interactive website, Chester County – Water Conditions for 2022. Check out the site to view the results of water quality sampling conducted at eighteen monitoring sites across Chester County. You’ll also find data from the past 25 years for biotic integrity, nitrate, phosphorus, and chloride, as well as links to the USGS website for additional information.

This resource will continually be updated as new data becomes available. Please feel free to reach out with questions or to provide recommendations so that we can improve these outreach products.

Rainfall, Groundwater Levels, and Stream Flows

While recent storms have brought heavy rains and flooding to many parts of Chester County and the state, groundwater levels have not yet fully recovered. With the scattered nature of the recent storms, as well as a precipitation deficit over the past 6 months, groundwater levels for certain observation wells in Chester County are still lower than normal.

Following a meeting of the Commonwealth Drought Task Force on July 27, 2023, the Pennsylvania Department of Environmental Protection (DEP) is maintaining a statewide drought watch. While not required, residents and non-farm businesses are encouraged to voluntarily conserve water by reducing their nonessential water use. Additional information is available at the Chester County Drought Dashboard.
