Development of 3D Aquifer Maps

It is surprising that New Mexico does not have a detailed map of all of the productive and accessible aquifers across the state. In a state with as little as 0.24% of our land surface covered with water (the least in the country!), having detailed maps of our groundwater resources and aquifers, is essential. Some of our neighboring states, like Texas and Colorado, have these maps already available, and are successfully being used to administer and conserve water. We have started a new multi-year project to develop 3D maps of aquifers.

Estimating Groundwater Recharge for the Entire State of New Mexico

Groundwater is replenished by a process called recharge, where snowmelt and rain infiltrates through the soil and slowly moves through the subsurface to eventually reach an aquifer. Because groundwater recharge defines a limit for the availability of groundwater, estimating recharge for the state of New Mexico is necessary for effective water resource management.

Monitoring the recovery of Santa Fe's Buckman Water Well Field

High-production municipal water well fields can depress water levels, cause land subsidence, and disturb subsurface aquifer temperatures. As an example, the City of Santa Fe’s Buckman well field located along the Rio Grande, was pumped at high rates from 1989 to 2003. This high-rate pumping led to a precipitous drop in water level (>100 m), caused measureable ground subsidence over a 25 km2 area (based on 1995-1997 InSAR [satellite-based] data), and created a land-surface fissure with 20 cm of vertical displacement. Pumping rates were reduced after 2003 and water levels have since risen ~120 m.

Public-private investment in New Mexico’s water future

The hydrogeology studies group (known as the Aquifer Mapping Program), at the New Mexico Bureau of Geology and Mineral Resources, received an important gift in 2016 from the Healy Foundation to benefit the New Mexico’s water and natural resources. The funds will be used to support two new water-focused, multi-year programs for the state.

Southern Taos Valley Hydrogeology

Since 1987 the bureau has been working in southern Taos County on detailed geologic mapping of the northern Rio Grande Valley. In 2011, in response to concerns regarding groundwater availability in the Taos area, the bureau initiated a multi-year hydrogeologic study of the southern Taos Valley, southwest of Taos.
