Vinyl Chloride
Contamination Found in Illinois Wells
April 10, 2006
Several months ago, a DuPage County Health
Department well-testing program detected vinyl chloride in 21 of
33 wells in Wayne Township, Ill, the Daily Herald reported. The
highest levels were 4.59 ppb; the federal safe-drinking standard
is 2 ppb. Expanded testing found nine out of 11 additional wells
polluted with vinyl chloride. The highest level was 10.6 ppb.
A chemical used to make plastics, intense
exposure to vinyl chloride has been linked to health problems
such as liver or kidney damage and cancer. Studies have shown it
can harm pregnant animals and fetuses.
According to some, one possible source of the
pollution is the former landfill at Mallard Lake Forest Preserve
in Hanover Park, about 2 miles northeast of the contaminated
wells. Illinois Environmental Protection Agency experts,
however, have not confirmed the source. DuPage County Forest
Preserve District officials said the landfill is not the cause.
In addition to health concerns, residents must
deal with the expense of connecting to Lake Michigan water
through a plan organized by DuPage County. Residents have been
meeting with county officials to discuss options including
installing a water main paid for by a special tax. The DuPage
Water Commission might provide loan money to help pay for the
project.
At a March 29 meeting, homeowners learned it
could cost $1,000 or $2,000 annually for 20 to 30 years,
depending on the loan, plus individual hookup costs estimated at
$4,000.
The county board is expected to vote on
starting the special service area process Tuesday. Unless a
majority of residents object, the water main could be built by
fall, according to the Daily Herald.
