Hydrogeology of the Questa Area

The issues are a gap in regional scientific information for deep and shallow, sediment-volcanic aquifers and surface waters in the Questa area; including sustainable sources of drinking water, sources of water to springs and streams that feed fisheries and discharge to the Rio Grande, the character of natural, background water quality, and possible impacts from mine-related waters.

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.

Critical Minerals in Mine Wastes

There are tens of thousands of inactive mine features in 274 mining districts in New Mexico (including coal, uranium, metals, and industrial minerals districts). However, many of these mines have not been inventoried or prioritized for reclamation or reprocessing. Many of these mines have existing mine wastes, generated during mineral production, which could have potential for critical minerals, especially since the actual mineral production was generally for precious and base metals and not critical minerals. The purpose of this project is to inventory, characterize and estimate the critical mineral endowment of mine wastes using USGS sampling procedures. This project is important to the state of New Mexico because critical mineral resources must be identified before land exchanges, withdrawals or other land use decisions are made by government officials. Future mining of mine wastes that potentially contain critical minerals will directly benefit the economy of New Mexico. Possible re-mining and/or reprocessing of mine wastes could clean up these sites and pay for reclamation. Furthermore, this project will include training of younger, professional geologists and students in economic and reclamation geology by the PIs.
