ALORTON, ST. CLAIR COUNTY, ILLINOIS
The Illinois Environmental Protection Agency (IEPA) requested that the Illinois Department of Public Health (IDPH) conduct a health evaluation of the Childs Property site. IDPH staff reviewed the available historical and environmental data associated with the site to determine if a threat to public health exists.
The Childs Property site is on 5.63 acres at 3607 E. Missouri Avenue, Alorton, Illinois (Figure 1). The property is bordered by Missouri Avenue to the southwest and Aluminum Corporation of America (ALCOA) property on the other three sides (Figure 2). The area in and around the site is primarily abandoned industries. Currently, no active businesses are on the site. A brick recycling facility is on the old ALCOA property west of the site. The site is not fenced, but a gate has been installed to deter dumping. The site is heavily vegetated.
IEPA's Collinsville Regional Office staff received a complaint about open dumping at the site on August 14, 1989. They visited the site on August 16, 1989, and conducted a sampling inspection on August 22, 1989. IEPA found evidence of random dumping of general refuse and open burning of waste (including tires). Four drums were on the site, and IEPA staff noted a solvent odor. Due to the corroded condition of the drums, IEPA staff sampled only one drum. The material inside was a dark brown oily liquid that was analyzed for volatile organic compounds (VOCs), flash point, and polychlorinated biphenyls. The sample results showed that VOCs were present.
On June 18, 1993, IEPA conducted a follow-up inspection at the Childs Property. The amount of waste on the site had greatly increased since the original inspection in 1989. More than 100 drums and several 5-gallon buckets and smaller containers were on the site. Also, hundreds of tires and numerous piles of general refuse were on site. In a subsequent follow-up inspection on October 28, 1993, IEPA found approximately 127 55-gallon drums abandoned on the site.
Between April 1994 and July 1994, the U.S. Environmental Protection Agency (USEPA) sampled and staged drums for removal, consolidated compatible materials, secured the site, and removed empty and full containers. Approximately 160 drums, 24 gas cylinders, and 1 storage tank that held approximately 3,000 gallons of waste were removed from the site. The wastes were primarily paint wastes, solvents, resins, oil, and acids. The removal action was for the contained waste. No mention was made about whether surface contamination existed onsite.
IEPA conducted an Integrated Assessment site inspection on November 25, 1996. IEPA collected seven on-site surface soil samples and one duplicate sample. The samples were collected to determine if areas of contamination were present in on-site soils. The soil samples were collected with stainless steel trowels. The sample locations are shown in Figure 2. The samples were taken in areas where drums and other waste containers were suspected to have been stored. Sample collectors did not see any visual surface contamination during the sampling event.
