Final Environmental Assessment and
Finding of No Significant Impact
Record drought in the southwestern United States continues to threaten domestic water supplies with severe shortages. The Regina Mutual Domestic Water Consumers Association (Association) of New Mexico, is dependent on groundwater for its water supply, which is pumped from an existing small-capacity groundwater well located approximately 10 miles north of Cuba, New Mexico. The existing well depth is approximately 1,500 feet and pulls water from the San Jose Formation, which is composed of sandstones and shales. Prolonged periods of drought can have a negative impact on groundwater levels, often requiring the need for deeper and more expensive wells.
The Association’s existing groundwater well produces less than 50 gallons per minute with several hundred feet of drawdown in the well. A new well is needed to supplement the Association’s existing water supply in case of emergency. Precipitation in the area averages about 13 inches per year, but may vary from less than 10 inches for several consecutive years to more than 16 inches. The seasonality of the precipitation and the lack of high-quality surface water sources in the area make a reliable groundwater source extremely important to the Association’s members. Support for drought emergency well drilling was authorized by the U.S. Congress in Title 1 of the Reclamation States Emergency Drought Relief Act of 1991.
