Chester County 2018 Impaired Waters Map Series

In Chester County there were 16 unique causes for water impairments per the 2018 Integrated List. Chester County Water Resources Authority has developed a map series that shows the locations of streams listed as "impaired" by PADEP. The 2018 Integrated Water Quality report was published as a final document
in November 2019 (link to report on the PADEP web site).
The map series begins with a map that includes all causes of impairment, followed by 15 maps that show the location of streams that are "impaired" by unique causes of impairment.  

Map IW-1-2018 illustrates all streams that have 
at least one listed impairment.
