Health assessment for Times Beach Site, Times Beach, St. Louis County, Missouri, Region 7. CERCLIS No. MOD980685226. Final report

Technical Report · Fri Feb 19 04:00:00 EST 1988

OSTI ID:5164396

The Times Beach National Priorities List site is situated on the banks of the Meramec River in St. Louis County, about 30 miles southwest of St. Louis, Missouri. The roads within the City of Times Beach have been contaminated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). After the 1982 flood, the City of Times Beach was evacuated and access has been restricted to only authorized personnel. Potential exposure pathways that could result from the site include ingestion of contaminated soil and fish or game animals that have bioconcentrated TCDD, dermal absorption upon contact with tainted soil, and inhalation of TCDD-entrained fugitive dusts. Flooding of Times Beach in 1982, 1983, and 1985 may have resulted in the migration of some TCDD off-site into the Meramec River. The levels of TCDD at the site are of concern and warrant continued site-access control, prevention of sediment runoff, and eventual removal of the TCDD.
