What's New


  • Chester County 2014 Impaired Waters Map Series (Impairments as of 2014 PADEP Report)
    • The 2014 Pennsylvania Integrated Water Quality Monitoring and Assessment Report is now final and lists the most recent stream impairments in the state of Pennsylvania. CCWRA has updated the Chester County Impaired Waters Map Series showing the latest stream impairments in Chester County from this report.
    • Of the 2,348 miles of streams in Chester County, Pennsylvania Department of Environmental Protection (PADEP) routinely assesses 1,394 stream miles using an assessment methodology approved by the U.S. Environmental Protection Agency to determine if a stream is meeting water quality standards. In the 2014 report, PADEP listed 770 miles of streams in Chester County as impaired, which means they do not meet water quality standards. 
    • The list of impaired streams, as well as the list of streams assessed that met the water quality standards, are found in the "2014 Pennsylvania Integrated Water Quality Monitoring and Assessment Report" on the PADEP web site.

  • MapShed Model for the Christina Basin
    • CCWRA, with support from Dr. Barry Evans, has developed a watershed model using MapShed to support the Christina Basin TMDL Implementation Partnership efforts. For more information, please see our Christina Basin TMDL Implementation page.
