In Chester County there were 16 unique causes for water impairments per
the 2010 Integrated List. Chester County Water Resources Authority has
developed a map series that shows the locations of streams listed as
"impaired" by PADEP.
The map series begins with a map that includes all causes of impairment,
followed by 16 maps that show the location of streams that are
"impaired" by unique causes of impairment.
