After finding moderate levels of airborne trichloroethene (TCE) at
the nearby Pottstown monitoring site, the DEP expanded monitoring to the Collegeville
area. Results from an initial survey showed elevated levels of TCE at several
locations within the Borough. In 2005, DEP committed to establishing stationary
monitoring locations in the Collegeville area. In addition, the two major facilities
in the Collegeville area committed to voluntary emission reduction efforts.
The scope of the project was greatly expanded when the EPA awarded DEP a grant
in 2008. A report on the project was issued in November 2009 and the major findings
include: a statistically significant decreasing trend in TCE concentrations from
2007 to 2008, TCE concentrations well under the acute and intermediate-term risk
levels, excess lifetime cancer risk to residents in the Collegeville area is comparable
to the risk found at other urban sites in the state.
Sampling will continue
at two sites (Collegeville and Evansburg UM) through 2011 and beyond until further notice.
For 2011 a second (collocated) sample was collected at the Collegeville site. This sample was collected simultaneously with the primary sample every other sample day for data quality control purposes.
