ALBUQUERQUE, N.M. (AP) – The federal government and Colorado have made little progress in remedying damage from the release of millions of gallons of wastewater from a southern Colorado mine last year, New Mexico’s top prosecutor charged in a pair of scathing letters sent to officials this week.
The wastewater, which contained arsenic, copper, lead, mercury and other dangerous pollutants, rushed down a Colorado mountainside and eventually fouled rivers in three Western states, setting off a major response by government agencies and private groups.
Attorney General Hector Balderas wrote to the head of the U.S Environmental Protection Agency and Colorado officials as New Mexico’s threat to sue the agency, the neighboring state and two mining companies remains on the table.
Balderas said New Mexico reached out to discuss independent monitoring and remedial measures in the wake of the spill, but he’s concerned about the lack of progress.
New Mexico’s requests have been disregarded and minimized, he said.
