Wayne Township Groundwater Contamination
The DuPage County Health Department (DCHD) began a sampling program in 2005
to test private wells in the county for potential chemical threats. After
testing was completed for roughly one thousand wells, two areas of contamination
emerged. In one part of the county, there was a small area of contamination
with methyl tertiary butyl ether (MTBE). The
concentrations discovered were not a health hazard, however. DCHD informed
the well owners of the presence of the contaminant and gave advice about
how to reduce exposure. In Wayne Township, the well testing revealed vinyl
chloride and cis-1,2 dichloroethene in a number of private wells in unincorporated
areas.
