Site DescriptionThe Grand Traverse Overall Supply Company site was a commercial laundering and dry cleaning facility covering one acre in Greilickville, Leelanau County, Michigan. The facility was built in 1953, and dry-cleaning machines were installed in 1968 and 1973. The facility is no longer used for dry cleaning, and the machines were removed in the early 1980s. A dry well was used to collect waste until 1955, but seepage lagoons were constructed in 1955, 1961, and 1968 and collected wastes until 1977 when the facility began discharging waste to the sanitary sewer system. In 1978, Michigan Department of Environmental Quality (MDEQ) discovered that groundwater in the area was contaminated with volatile organic compounds (VOCs) such as trichloroethylene (TCE) and perchloroethylene (PCE). At least 10 wells were found to be contaminated, including a well used by an elementary school adjacent to the facility. The school and other residences used bottled water until new wells in a deeper, confined aquifer were installed. The contaminated wells were abandoned when the new wells were drilled. In the late 1970s, the lagoons on the site were drained and filled with gravel, and contaminated soils around the dry well and barrels of waste sludge were removed. Approximately 1,200 people live within three miles of the site. The nearest residence is 250 feet south of the facility. Cedar Lake, Cedar Lake Outlet, and Grand Traverse Bay are all less than 2,000 feet away from the site. Cedar Lake and Grand Traverse Bay are used for swimming and other recreational activities.
Site ResponsibilityThis site is being addressed through federal actions.
Threats and Contaminants
At this time no one is exposed to the groundwater contamination. Everyone in the area is on a public water supply well. The building on the GTOS property was removed under the time critical removal action. The removal program conducted a vapor intrusion study at the Former Norris Elemetary school next door to the property. VOC vapors were not detected inside the school but were detected under the foundation of the school building. A vapor extraction system is currently operating to maintain clean indoor air at the school building.
A groundwater plume had been defined moving off the GTOS property. The Agency anticipates installing a groundwater pump and treat system following soil removal activites at the site.
MDEQ had the contaminated wells replaced by new, deeper wells. In addition, the lagoons were drained in the late 1970s, and sludge and contaminated soils were removed. In 1988, United States Environmental Protection Agency (EPA) began a study to determine the nature and extent of the groundwater, soil, and surface water contamination at the site. The study, completed in 1992, showed that the initial cleanup actions had addressed the threats to the people and the environment. In 2001, MDEQ conducted a Phase I investigation as part of a site review. The investigation found previously unidentified groundwater contamination near the facility building. Because of this investigation, In 2006, EPA conducted a Site investigation of the GTOS plant area and groundwater and determined that additional contamination remains on site under the GTOS building. This contamination is moving off site directly to Grand Traverse Bay in a groundwater contamination plume. A site investigation, risk assessment and feasiblity study have been completed for the site and have determined that VOC contamination associated with dry cleaning operations at the site poses a future risk to human health and the environment. Another removal action is under way to demolish the on site building to aid in the clean up of contaminated soils under the building.
The removal program completed removal actions at the site. The remedial program is currently taking over actions at this site. Site Cleanup options where evaluated at the Site and a Record of Decision was issued to remove contaminated soils remaining following the removal action, install a pump and treat system to treat the contaminated groundwater plume, and continue operating the vapor extractions system at the former Norris School building. The Agency is also conducting quarterly sampling to monitor the groundwater and surface water in the area of the site.
Soil removal was completed in December 2011. The groundwater treatment system is currenly being designed and is expected to be build and operational beginning in May 2012.
Property ReuseThe property is currently not being used. A propsective purchaser has approached Leelanau count the current owner of the property to purchase it and turn it into a parking lot for use with the building next door.
