Abandoned Mine Lands: Deciding the Future of Toxic Contamination
On August 5, 2015, EPA personnel assigned to mitigate pollutants from the foreclosed Gold King Mine in Colorado caused the discharge of toxic wastewater into the Animas River watershed, releasing lead, arsenic, and other metals and toxic elements. Even though Colorado Governor Hickenlooper eventually declared the area a disaster zone, the delayed response and devastating environmental impacts from the Gold King Mine wastewater spill revealed an urgent need to address the nearly 500,000 Abandoned Mine Lands throughout the United States. According to the EPA, the total cost to clean up AMLs ranges from $50-70 billion. Although the burden of mitigating toxic pollutants from AMLs may appear to rest solely upon the federal government, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) mandates that the party responsible for AML hazardous contamination must assume financial responsibility.
