In Chester County there were 13 unique causes for water impairments per
the 2014 Integrated List. Chester County Water Resources Authority has
developed a map series that shows the locations of streams listed as
"impaired" by PADEP. The 2014 Integrated report was published as a final
in December 2014 (link to report on the PADEP website).
The map series begins with a map that includes all causes of
impairment, followed by 13 maps that show the location of streams that
are "impaired" by unique causes of impairment.
