N.M. Begins Cleanup at Superfund Site in Carrizozo
Associated Press
SANTA FE — The state Environment Department has started cleaning up the Cimarron Mining Corp. Superfund site in southern New Mexico.
The project is aimed at preventing low levels of cyanide from seeping into groundwater at the 10-acre site in Carrizozo. The project, estimated to cost more than $141,000, will be completed Friday.
Workers are filling depressions at the site to stop water from collecting and filtering into the shallow aquifer.
Cimarron Mining used a solution of cyanide salt and metal stripper to recover metal from ore transported to the site between 1979 and 1982.
The mill was previously operated by Sierra Blanca Mining and Milling Co. for the extraction of gold with cyanide. Both processes generated liquid waste containing cyanide and heavy metals.
