Title: Health assessment for Crab Orchard National Wildlife Refuge, Marion, Illinois, Region 5. CERCLIS No. IL8143609487. Final report

Technical Report ·
OSTI ID:5184403

Crab Orchard Lake is the primary water supply for the National Wildlife Refuge and the U.S. Federal Penitentiary. The City of Marion also withdraws water from this lake to supplement their drinking water supply during late summer and early fall. The Sangamo Electric Company dump (1946-1964) lies next to the lake and about 1/2 mile south of the City of Marion's water-supply intake. The 2.5-acre closed landfill lies next to Olin Corporation and drains into the lake. High levels of PCBs (20,594 ppm) have been detected in the landfill soils. Lower levels (3.3 ppm and lower) have been found in the lake sediments near the site. Elevated levels of chloroform and/or trihalomethanes have been found in the drinking water from the Refuge water supply/treatment systems (WSTS) at various distribution points in the U.S. Federal Penitentiary (0.245 ppm or mg/L), and from the Marion WSTS (0.252 mg/L, location unknown). Because the data provided are not current but several years old, the present public health threat from ingesting drinking water from these sources cannot be determined.
