A copper mining company in Arizona has agreed to pay $825,000 to settle a federal lawsuit citing them for release of hazardous substances at one of their mining sites. The Environmental Protection Agency reached an agreement with the company requiring the clean up a portion of the mine site after reporting high levels of sulfate and uranium in the area resulting from evaporation ponds and mill tailings. The contaminated aquifer was previously the sole source of drinking water for the community. The settlement includes funds for restoration projects.
