Superfund Site: EASTERN MICHAUD FLATS CONTAMINATION, POCATELLO, ID
Superfund Site Profile
The 2,530-acre Eastern Michaud Flats Contamination site is located near Pocatello, Idaho. Two on-site phosphate ore processing facilities, the FMC Corporation and the JR Simplot Company, began operations in the 1940s. The J.R. Simplot facility produces solid and liquid fertilizers using phosphate ore, sulfur, air and natural gas. The FMC plant produced elemental phosphorus for use in a variety of products from cleaning compounds to foods. Operations at both plants contaminated groundwater and soil with hazardous chemicals. Site cleanup is underway.
