Animas River Valley - Long Term Groundwater Monitoring
Our agency collaborated with the New Mexico Environment Department (NMED) on a hydrogeology study along the Animas River in New Mexico in response to the Gold King Mine spill, which occurred in August 2015. The water released from the spill was loaded with dissolved metals and contaminated sediments, which posed a possible risk to groundwater quality in the Animas Valley. This study, wihch included two phases, primarily focused on identifying potential adverse impacts on groundwater quality related to the Gold King Mine spill.
