Health assessment for Sheffield (US Ecology, Inc. ), Sheffield, Bureau County, Illinois, Region 5. CERCLIS No. ILD045063450. Preliminary report

Technical Report ·
OSTI ID:5184694
The Sheffield (aka US Ecology, Incorporated) site is listed on the National Priorities List. The site is a 45-acre area formerly known as Nuclear Engineering Company and consists of three inactive disposal areas which include a low-level radioactive waste area. Waste disposal activities began in late 1967, and at one time, the site was the largest disposal facility in Illinois. The environmental contamination on-site consists of methylene chloride (78,000 ppb), chloroform (49,000 ppb), trichloroethylene (11,000 ppb), benzene (690 ppb), tetrachloroethylene (83,000 ppb), and toluene (550 ppb) in groundwater; and polychlorinated biphenyls (500 ppb), endrin (1,900 ppb), and dieldrin (10 ppb) in soil and lake water. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via contaminated ground water, and surface water in the future. The extent of radioactive waste contamination is considered to be of potential public health concern, also.
