Arsenic at levels beyond those considered safe by state regulators has been found on the Mission Hills Country Club property where Red Seal wants to build 137 homes, according to environmental test results filed June 29 in Cook County Circuit Court.
Those tests, by Huff & Huff, Inc., of Oak Brook
, were commissioned by Mission Hills homeowners trying to stop Red Seal's Provenance project on the course between their buildings. The test report stated that all of the seven greens tested on June 16 exceeded the amount of arsenic allowed by the Illinois Environmental Protection Agency
by 23 to 277 percent, according to court documents.
Both sides say the arsenic is left over from herbicides or pesticides commonly used on golf courses decades ago. The Mission Hills course has been in operation for almost 100 years, according to court documents.
Circuit Court Judge Rita Novak ruled last month that Red Seal had to allow the environmental testing as part of an ongoing lawsuit brought in May 2015 by seven Mission Hills homeowners associations to stop construction on the open space adjacent to their homes.
