Water and sediment leachate chemistry from the San Juan Generating Station, Waterflow, NM, January 2021

The San Juan Generating Station in Waterflow, NM, owned by the Public Service Company of New Mexico (PNM) is a coal-fired power plant that operates on coal mined on the same property. This plant is scheduled to shut down in 2022. In light of this impending closure, the Bureau of Reclamation (Reclamation) is interested in purchasing the plant's raw-water reservoir for use in the Navajo-Gallup Water Supply Project (NGWSP). Concerns about contamination leaking from the reservoir or being mobilized by groundwater flow affected by the leaking reservoir have resulted in Reclamation eliciting a short study of the water and sediment chemistry surrounding the reservoir and the recovery system set up by PNM. The U.S. Geological...

The Fort Stanton-Snowy River cave system (FSC) is located in Lincoln County, New Mexico in the upper Rio Hondo Basin. The entrance of the cave is on Bureau of Land Management (BLM) land near the site of historic Fort Stanton. In 2001, the Snowy River Formation was discovered. This formation, a white calcite deposit that lines a streambed within the cave, is now considered to be the largest cave formation in the world. Initially thought to be hydrologically inactive, the Snowy River passage has intermittently flooded in response to large precipitation events such as the passage of Hurricane Dolly in 2008 and a large spring snowmelt runoff in 2010. There is interest in determining the source of the water that flows...

As part of the Navajo-Gallup Water Supply Project, the Bureau of Reclamation was tasked with design and construction of infrastructure to treat and deliver potable water to the communities of Navajo Nation, parts of the Jicarilla Apache Nation, and City of Gallup. The Bureau of Reclamation has been evaluating the Public Service Company of New Mexico's (PNM) San Juan Generating Station (SJGS) reservoir as a possible water storage and sediment settling basin for the Navajo-Gallup Water Supply Project. The U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation, was tasked with collecting reservoir sediment cores and pore water from SJGS reservoir. This data release contains reservoir sediment...

Scanning electron microscopy data from sediments collected in ephemeral channels, Four Corners region, USA, 2021-2022

The San Juan River is a major water source for communities in the Four Corners region of the United States (parts of Colorado, Arizona, New Mexico, Utah) and is a vital source of water for the Navajo Nation. The Navajo Nation Environmental Protection Agency (NNEPA) periodically samples surface water on the Navajo Nation and has found that some elements exceed NNEPA surface water standards (the upper limits of an element for consumption or other use of water). Constituents of concern are substances that could be harmful if present in sufficient quantities, and it is important to monitor the concentrations of these substances in the environment. In the San Juan River, constituents of concern include metals detected...
