BACKGROUND AND STATEMENT OF ISSUES
The Illinois Environmental Protection Agency (IEPA) requested that the Illinois Department of Public Health (IDPH) perform a health consultation for the Bunn Park Industries site. The purpose of this health consultation is to evaluate any known or potential adverse human health effects that may result from exposure to site contamination. This health consultation relies on the site information currently available.
The Bunn Park Industries site is north of Truman Road and east of Bunn Park in Springfield, Sangamon County, Illinois (Attachment 1). The site is in the North ½ of the Northwest ¼ of Section 11 and the South ½ of the Southwest ¼ of Section 2, Township 15 North, Range 5 West of the Third principal Meridian in Sangamon County, Illinois. The site consists of approximately 49 acres and contains an inactive landfill.
The area surrounding the site is residential to the east and west, wooded to the north, and industrial to the south. The Illinois Central Railroad tracks and private homes beyond the tracks border the site on the west. Truman Road borders the southern portion of the site, and an industrial area is beyond Truman Road. The eastern border consists of private homes, and a wooded area with an unnamed tributary of Sugar Creek on the north and east. The nearest home is about 50 feet from the site. The population within one mile of the site consists of about 12,000 people.
The southwestern portion of the site consists of a privately owned area, the Four Seasons Recreational Park, which consists of several softball diamonds, a clubhouse, and sand volleyball courts (Attachment 2). The eastern section of the site contains large gravel mounds, and the remaining area is vegetated, open land. The nearest surface water body is an unnamed tributary of Sugar Creek, which joins Sugar Creek approximately one mile east of the site. Sugar Creek continues about six miles and joins the Sangamon River. Lake Springfield, the source of drinking water for the city of Springfield, is about two miles southeast of the site. There is little groundwater usage in the area, and there are no surface water pathways from the site to Lake Springfield (1). No residents use private wells within a 4-mile radius of the site. Sugar Creek, Lake Springfield, and Sangamon River are all used for recreation purposes.
IDPH does not know if fencing was in place on the property during past landfill operations. Currently, the site is not fenced and is easily accessible to persons from the recreation park and residential areas near the site.
The site was originally operated by Merle Buerkett and owned by Bunn Park Industries. The exact date the landfill began accepting wastes is unknown. Bunn Park Industries was added to the Comprehensive Environmental Response, Compensation, and Liability Information System after a citizen complained that the site was operating as a landfill without a permit in November 1973. In November 1974, Bunn Park Industries was issued a permit to accept construction and demolition waste in addition to general refuse. A supplementary permit was granted to allow the acceptance of liquid cutting oil wastes in December 1974. Hazardous wastes could have been disposed illegally on the site before November 1974.
IEPA visited the site in January 1975 and discovered that wastes were no longer being accepted and that operations had ceased. IEPA determined that the final cover placed on the landfill was inadequate at that time. During a 1978 site inspection, IEPA observed leachate flows in the northeast and northwest areas of the site. The leachate on the northwest side of the site was flowing toward the unnamed tributary of Sugar Creek (1).
In May 1982, IEPA conducted a site inspection and determined that the landfill was now adequately covered and satisfactorily closed (1). Concrete and asphalt were found mixed with the cover material in some areas of the site. The northwest corner of the site was rip-rapped with concrete to slow erosion (Attachment 3); however, no engineered structures were in place to prevent surface water runoff from entering the unnamed tributary of Sugar Creek. Currently, there is no liner, leachate collection system, gas collection system, or methane vents in place at the site.
In March 1987, IEPA conducted a Site Screening Inspection (SSI) that included the collection of two leachate samples and one sample from an on-site monitoring well (2).
IDPH visited the site in September 1997. The Four Seasons Recreation Park was observed on the southwest section of the site. A mobile home park was present to the west of the site. A wooded area was observed on the northern portion of the site. On the eastern section of the site, workers were present, and large mounds of gravel were in that area. The site was easily accessible to IDPH personnel.
IEPA performed a Site Team Evaluation Prioritization (STEP), during which sediment and surface water samples were collected, on November 24, 1997 (3).
IDPH compared the concentration of each groundwater and soil contaminant with the appropriate screening comparison value used to select contaminants for further evaluation for carcinogenic and non-carcinogenic health effects. Chemicals found at levels greater than comparison values or those chemicals with no comparison values were selected for further evaluation. A discussion of each of the health screening comparison values used is found in Attachment 4.
During the 1987 SSI, two leachate samples, X101 and X102, were collected from the north side of the site. One sample from the only on-site groundwater monitoring well, G103, was also collected (Attachment 5). No volatile organic compounds were detected at levels above comparison values in the leachate samples. Naturally-occurring metals were detected, but not at levels greater than background. No contaminants were found in the groundwater sample at levels above comparison values (2).
While performing the STEP in November 1997, IEPA collected five sediment samples (X103, X104, and X105), including two background samples (X101 and X102). Other samples taken included two background surface water samples (G501 and G502) along with one leachate sample (G503) and a downstream sample (G504) (Attachment 6). No contaminants were found at levels of health concern (3).
Based on the information reviewed, IDPH concludes that no apparent public health hazard presently exists from contamination at Bunn Park Industries. No completed exposure pathways presently exist at this site. The lack of a liner, leachate collection system, gas collection system, and methane vents at the site could pose problems in the future. IDPH will reevaluate the site in the future should any change in site conditions occur that could threaten public health.
IEPA should monitor the site for any change in conditions that might require a health evaluation.
