Geochemical Evidence of Groundwater Flow Paths and the Fate and Transport of Constituents of Concern in the Alluvial Aquifer at Fort Wingate Depot Activity, New Mexico
As part of an environmental investigation at Fort Wingate Depot Activity, New Mexico, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, interpreted aqueous geochemical concentrations to better understand the groundwater flow paths and the fate and transport of constituents of concern in the alluvial aquifer underlying the study area. The fine-grained nature of the...
Hydrogeologic and geochemical characterization and evaluation of two arroyos for managed aquifer recharge by surface infiltration in the Pojoaque River Basin
In order to provide long-term storage of diverted surface water from the Rio Grande as part of the Aamodt water rights settlement, managed aquifer recharge by surface infiltration in Pojoaque River Basin arroyos was proposed as an option. The initial hydrogeologic and geochemical characterization of two arroyos located within the Pojoaque River Basin was performed in 2014 and 2015 in cooperation...
The Source of Groundwater and Solutes to Many Devils Wash at a Former Uranium Mill Site in Shiprock, New Mexico
The Shiprock Disposal Site is the location of the former Navajo Mill, a uranium ore-processing facility, located on a terrace overlooking the San Juan River in the town of Shiprock, New Mexico.The milling operations, conducted at the site from 1954 to 1968, created radioactive tailings and constituents of concern that are now found in the groundwater beneath the Mill. Elevated concentrations of...
Transboundary Aquifer Assessment Program (TAAP)
Many communities along the U.S.-Mexico border have limited surface water supply and rely on transboundary aquifers for industry, agriculture, and drinking water; however, information on water needs, water quality, and the extent and functioning of these aquifers is incomplete. The Transboundary Aquifer Assessment Program (TAAP), established through a binational agreement between the United States...
Transboundary Aquifer Assessment Program (TAAP)
Transboundary aquifers are an essential source of water for United States – Mexico border communities. Declining water levels, deteriorating water quality, and increasing use of groundwater resources on both sides of the border raise concerns about the long-term availability of this supply. The U.S. – Mexico Transboundary Aquifer Assessment Act (Public Law 109-448) of 2006 was enacted to conduct...
Water Resource Assessment of the Rio San Jose Basin, West-Central New Mexico
Water resources in the Rio San Jose Basin are limited, and development for public supply, mining, agriculture, and commercial activities have the potential to affect the water availability and quality at a basin-wide scale. This study is designed to provide water-resource managers with better information to plan for potential effects of increased or shifting demands and changes of climatic...
Monitoring Network of the Groundwater Flow System and Stream-Aquifer Relations in the Mesilla Basin, Doña Ana County, New Mexico and El Paso County, Texas
The Mesilla Basin monitoring program was established in 1987 to document the hydrologic conditions of New Mexico’s southern-most, Rio Grande rift basin. The program’s data collection and reporting is conducted by the U.S. Geological Survey in cooperation with local, state, and federal agencies. Hydrologic data collected as part of the monitoring program provide valuable information to better...
