Unique combinations of geologic setting, aquifer characteristics, and recharge and discharge areas define 22 major aquifer regions across New Mexico. The map, which is derived from the Ground Water Atlas of the United States, indicates the areal extent of the uppermost principal aquifers on a national scale. Since the early 1990s, our staff have been engaged in hydrogeologic studies of New Mexico's aquifers in cooperation with partners at the New Mexico Office of the State Engineer, the New Mexico Environment Department, the U.S. Geological Survey Water Resources Program, and … Each region has a set of principal water resource targets and challenges to water resource management. Attribution: Region 7: Upper Colorado Basin , New Mexico Water Science Center The U.S. Geological Survey (USGS) in New Mexico, in cooperation with the New Mexico Office of the State Engineer (NMOSE) and other Federal, State, and local agencies, currently monitors 5,000 groundwater wells dispersed throughout New Mexico in a 5-year rotation that have been measured continually since 1925; some well records go back even further. OurAquifer Mapping Program conducts hydrogeologic research for the state of New Mexico. Hydrogeology is the science of hydrology and geology as it relates to the movement of groundwater and its distribution within the Earth’s aquifers. Aquifers: Map of the Principal Aquifers of the United States The areal and vertical location of the major aquifers is fundamental to the determination of groundwater availability for the Nation.
