MCLEAN COUNTY LANDFILL, INCORPORATED
BLOOMINGTON, MCLEAN COUNTY, ILLINOIS
The Illinois Environmental Protection Agency (IEPA) requested that the Illinois Department of Public Health (IDPH) review the historical and environmental data available to determine if a public health threat exists at the McLean County Landfill site. Hazardous compounds have been identified in groundwater, surface water, and soil. The site is on the Comprehensive Environmental Response Compensation and Liability Act Inventory System (CERCLIS) list.
The McLean County Landfill site is an inactive landfill on West Oakland County Road near the city limits of Bloomington, Illinois, in McLean County (Attachment 1). The site is in the southwest quarter of Section 7, Township 23 North, Range 2 East. The site is southwest of Interstate 55, and is about 1 mile southwest of Bloomington's central business district (Attachment 2). The site is situated on approximately 110 acres surrounded by agricultural and residential areas, including a housing development on Six Points Road. It is bounded on the north and west by Sugar Creek, on the south by Six Points Road, and on the east by West Oakland County Road.
The landfill is partially fenced. A fence is in place along West Oakland County Road south to Six Points Road, and fencing continues west on Six Points Road to Sugar Creek (Attachment 3). Sugar Creek is the nearest surface water and flows along the western portion of the site. A pond is on the north end of the site, and two more ponds are on the south end of the site. A soccer field is in the flood plain west of Sugar Creek at the intersection of Six Points Road and Rabbit Hill Road. The City of Bloomington owns the soccer field and operates it through the Bloomington Parks and Recreation Department.
The site is an open field that is slightly mounded and partially vegetated. Twelve monitoring wells have been placed around the perimeter of the landfill.
IDPH staff visited the site on December 17, 1997. Three campers were parked south of the landfill between the two southern ponds. A gate and an attendant weigh station is present at the site entrance to restrict access. However, at the time of the visit, the gate was open and no personnel were attending the station. The access road was muddy and snow covered.
The McLean County Solid Waste Coordinator reports that land next to the site has been purchased by American Disposal from the John Sexton Contractors Company. The land is used for a landfill and transfer station. This landfill uses the same entrance as the McLean County Landfill. Reportedly, most solid waste in McLean County goes to Livingston, Tazewell, or DeWitt County landfills.
Dr. Stanley D. Nord owned and operated the McLean County Landfill from 1964 until it closed in June 1990. During operation the landfill accepted municipal refuse, construction debris, industrial waste, and water treatment sludge. The site was initially investigated because of an anonymous telephone call to the McLean County Emergency Services and Disaster Agency on April 27, 1979. Following the initial site discovery in 1979, IEPA conducted a Preliminary Assessment (PA) in September 1984. The compliance record of the site showed inadequate daily and intermediate refuse cover, leachate flows, and ponding. As a result, the PA documented concern about the potential contamination of groundwater and surface water near the site by solvents, heavy metals, and acids. Subsequently, Ecology and Environment, Inc. (E&E) conducted a Site Inspection (SI) on August 19, 1987. The SI included groundwater, surface water, and sediment sampling. E&E also conducted a site reconnaissance visit on April 26, 1995. IEPA conducted the most recent groundwater sampling on November 5, 1997.
Approximately 37,000 residents of Bloomington and Normal obtain drinking water from residential and municipal wells within a 4-mile radius of the McLean County Landfill site. These water well systems draw groundwater from glacial sediments at depths ranging from 28 to 80 feet below the ground surface. The direction of groundwater flow near the site is thought to be south or southeast.
Based on a straight-line distance, approximately 5,000 people reside within 1 mile of the landfill. There are no schools or daycare centers within 0.5 miles of the site. A housing development is about 0.25 miles south of the site on Six Points Road. The nearest residential well is approximately 0.5 miles from the landfill.
Surface water from the site drains into Sugar Creek along the western boundary of the site. There are no known sensitive environments or drinking water intakes along Sugar Creek. It does not drain into any other surface body for 15 miles downstream. There are no berms or other engineered controls to prevent surface water runoff from the site to Sugar Creek.
