The San Andres-Glorieta aquifer in west-central New Mexico
— William D. White and T. E. Kelly

The Glorieta Sandstone and overlying San Andres Limestone act as a single hydraulic unit which produces large quantities of water to wells in west-central New Mexico. The San Andres has been subjected to two periods of karstification which have locally reduced the thickness of the limestone and also created secondary permeability which enhances water production.The Zuni Mountains arc the principal recharge area to the aquifer sequence; as much as 12,300 acre-feet of recharge occurs annually. Ground-water How is radial from the mountains. Well production ranges from dry holes to several thousand gallons per minute. Chemical quality of the water is generally less than 1000 mg/L. but quality variations are significant in the Acoma sag.
