Public Health Assessment for Weldon Spring Quarry/Plant/Pits (USDOE) St. Charles,St. Charles County, Missouri, Region 7. CERCLIS No. MO3210090004

摘要

The U.S. Department of Energy Weldon Spring Site Remedial Action Project(chemical plant site), is a former uranium processing facility located in eastern Missouri on the property of the former U.S. Army Weldon Spring Ordnance Works. Surface water, soil, sludge, sediment, and groundwater within the chemical plant site contain chemical and radioactive contaminants. The Agency for Toxic Substances and Disease Registry (ATSDR) reviewed on-site chemical exposure information and site conditions. ATSDR also prepared several Health Consultations on chemical and radioactive contaminants in areas on and off the DOE chemical plant site. ATSDR also reviewed on-site and off-site radiological exposure information and conditions. The exposure scenarios ATSDR evaluated include: trespassers swimming in quarry or raffinate pits; reservists performing field activities in the training area; anglers fishing, hunters haunting, and hikers hiking in the conservation areas; residents drinking from off-site private wells; staff and students attending the Francis Howell High School; and consumers of crops (e.g., corn) grown in conservation areas.
