Chester County Water Conditions January 2018 – June 2019 Report

The Chester County Water Resources Authority (CCWRA) recently completed a report summarizing data collected through the Chester County and U.S. Geological Survey Cooperative Water Resources Program from January 2018 to June 2019. The parameters summarized in the report provide insight into the County’s water conditions and help guide the management of the County’s water resources. Included in the report is information on precipitation amounts, groundwater levels, stream flow, biological diversity, various water quality parameters, such as nutrient and chloride concentrations, public water supply reservoir capacity, and surface water withdrawals.

2018 Assessed Waters Map Series (based on 2018 PADEP Water Quality Report)

PADEP published the “2018 Pennsylvania Integrated Water Quality Monitoring and Assessment Report,” which was approved by USEPA in November 2019. Of the 2,348 miles of streams in Chester County, PADEP periodically assesses 1,394 stream miles using an USEPA-approved assessment methodology to determine if a stream is meeting water quality standards. In the 2018 report, PADEP listed 957 miles of streams in Chester County as impaired which means they do not meet water quality standards.
