Methane gas investigation near Illinois landfill
United States Environmental Protection Agency (EPA) Region 5 is overseeing
an investigation of potential methane gas releases at homes along the western
and southern boundaries of the Mallard Lake Landfill, 26W580 Schick Road,
in Hanover Park, Illinois. About 20 homes have been screened, with more to
be screened in early December.
A team of local officials, including the Hanover Park Fire
Department, property owner Forest District of DuPage County, and landfill
operator BFI Waste Systems of North America are performing the investigative
work. Illinois EPA is working closely with EPA on oversight of the investigation.
High levels of methane are migrating into nearby neighborhoods,
though all data collected thus far shows the combustible gas at depths more
than 40 feet underground.
EPA’s involvement at the Mallard Lake Landfill grew out of previous
Illinois EPA work on environmental issues at the landfill.
