Public Health Assessment for Foote Mineral Company, Frazer, Chester County,Pennsylvania, Region 3. CERCLIS No. PAD077087989

摘要

The Foote Mineral site, seven miles south of Phoenixville, generated largeamounts of lithium and boron wastes since World War II. Concentrations of lithium up to 13,000 parts per billion (ppb) and boron up to 20,000 ppb have been detected in off-site private wells northeast of the site. A groundwater basin divide passes through approximately the center of the site such that volatile organic compounds (trichloroethene, tetrachloroethene, and benzene) migrate from the site (burn pit) westward for an unknown distance. At present, the site represents an indeterminate public health hazard. Although no adverse health effects have been identified in people exposed for short periods of time to levels of lithium and boron found in drinking water near the site, little information is available in the scientific literature on long-term, low-level exposure to lithium and boron.
