Health Consultation: An Evaluation of Radiation in Groundwater and Air, West Lake Landfill Operable Unit 1, Bridgeton, St. Louis County, Missouri. CERCLIS ID: MOD079900932, October 16, 2015.

摘要

The Agency for Toxic Substances and Disease Registry (ATSDR) is a federal public health agency. ATSDR’s mission is to serve the public by using the best science, taking responsive public health actions, and providing trusted health information to prevent harmful exposures to toxic substances. In 1973, the West Lake Landfill in Bridgeton, Missouri, received radioactive wastes mixed with soils to use as a cover for municipal wastes. In 1979, an adjoining quarry was licensed to receive more municipal and sanitary wastes. Currently in the adjoining landfill, a subsurface smoldering event ‘fire’ is believed to be slowly approaching the radioactive wastes. The surrounding community is concerned that the fire will reach the radioactive waste areas leading to additional contamination in the air and groundwater. They are also concerned that the radiological contamination has impacted their water supply. The US Environmental Protection Agency (USEPA) Region VII, Lenexa, Kansas, and the Missouri Department of Health and Senior Services (MDHSS) requested in February 2014 that ATSDR review and comment on groundwater, air, and soil data associated with past West Lake Landfill operations. In this public health consultation, ATSDR is evaluating these data with respect to their potential impacts to on-site workers and nearby residents.
