Andre Ritchie
Modeling and GIS Specialist, New Mexico Water Science Center
Andre Ritchie is a hydrologist in the hydrogeology and geochemistry program area at the New Mexico Water Science Center. Andre received a M.S. degree in Hydrology from the New Mexico Institute of Mining and Technology, and a B.S. degree in Geology from the University of North Carolina Wilmington. Since joining the USGS in 2015, Andre's work has been focused on using hydrogeology and integrated hydrologic modeling to answer questions relating to surface-water/groundwater interaction, farm-scale agricultural conjunctive use, and management of surface-water and groundwater resources.

Rio Grande Transboundary Integrated Hydrologic Model: Modeling Conjunctive Use to Support Resource Management
The Palomas, Mesilla, and Conejos-Médanos Basins in New Mexico, Texas, and northern Mexico compose a geologically and hydrologically complex region. The conjunctive use of surface water and groundwater takes place under a myriad of legal and operational constraints, including the Rio Grande Compact, an international treaty, and the U.S. Bureau of Reclamation’s Rio Grande Project. New demands are...
Potentiometric Surfaces and Groundwater-Level Changes
In the past, groundwater pumped from the Santa Fe Group aquifer system was the principal source of water for the Albuquerque metropolitan area of central New Mexico. The large quantity of groundwater pumping relative to recharge resulted in substantial drawdown in the aquifer system. In 2008 the Albuquerque Bernalillo County Water Utility Authority began diverting water from the San Juan-Chama...
Changes in Groundwater Levels in the Albuquerque Metropolitan Area
The U.S. Geological Survey, in cooperation with the Albuquerque Bernalillo County Water Utility Authority (ABCWUA) has been investigating the effects of groundwater withdrawal on groundwater levels throughout the Albuquerque metropolitan area in the Middle Rio Grande Valley of central New Mexico (fig. 1). Historically, the water supply requirements of the Albuquerque metropolitan area were met...
Aquifer Compaction, Recovery, and Land-surface Elevation Change in the Albuquerque Basin
In many groundwater basins in the arid to semiarid western United States, permanent regional-scale land-surface elevation change has resulted from substantial drawdown of groundwater levels. By the end of 2008, groundwater drawdown from municipal pumping in the Albuquerque area had reached as much as 120 feet below predevelopment (~1950s) water levels. In 2014 the USGS, in cooperation with the...
