Contamination cleanup to continue
Dry cleaning chemicals remain in underground plume

CHARLEVOIX — The U.S. Environmental Protection Agency will by month’s end host two informational meetings about plans to continue contamination cleanup from an old dry cleaning facility.
The public sessions will be from 1-3 p.m. and 5-7 p.m. on Wednesday, Oct. 29, in Community Room B at Charlevoix Public Library, 220 W. Clinton St., in downtown Charlevoix. Representatives of the EPA and the Michigan Departments of Environmental Quality and Community Health will be available to answer questions about the Superfund Site.
The next planned phase of cleanup might involve the removal of an underground storage tank at Grant and Antrim streets, said Steve Teunis, Charlevoix water superintendent.
“They want to further clean it up,” he said.
The Michigan Department of Public Health in 1981 notified Charlevoix officials the local water system showed contamination by volatile organic compounds. A new municipal water supply received approval four years later in an agreement with the U.S. Army Corps of Engineers. Meanwhile, federal environmental regulators attempted various cleanup methods, including water aeration.
Authorities also through the years identified several sources of the contaminated groundwater plumes, including trichloroethylene from the old middle school, and tetrachloroethylene from the former Art’s Dry Cleaners at Grant and Antrim streets, the former Hooker’s Dry Cleaners at Bridge and Hurlbut streets, a former dry cleaner at the corner of Garfield Street and McLeod Place, and finally, the former tool and die shop on Lincoln Avenue, according to EPA documents.
Environmental regulators obtained additional samples during winter months early this year. Results showed solvents in soil vapor and indoor air samples at 11 properties above levels that may pose an unacceptable human health risk.
Possible sources of this vapor intrusion are nearby former dry cleaners and manufacturers. Now, EPA officials plan to install systems to remove the solvent vapors from the soil, excavate the identified sources of the solvents, including that underground tank, and conduct more testing to better define the problem.
Teunis said Charlevoix’s municipal water supply currently comes from Lake Michigan and is free of this groundwater contamination.
No formal presentations will be made during the coming public open house sessions. Instead, these events will serve as an opportunity for members of the public to individually speak with federal and state regulators.
Janet Pope, of the EPA’s community involvement division, said anyone with questions about the meeting, or in need of special accommodations at the open house events, can call her at (312) 353-0628 or send her email at firstname.lastname@example.org online.
