New Mexico State University Researches Brackish Water Treatment Amid Funding Concerns

In a recent meeting of the New Mexico Legislature's House Energy, Environment, and Natural Resources Committee, lawmakers engaged in a critical discussion regarding the funding and research of water resources, particularly focusing on brackish water and produced water. The meeting, held on February 22, 2025, highlighted the complexities surrounding water rights and the implications of current legislative proposals.

A significant point of contention arose over the funding of a study related to produced water, which was not explicitly addressed in the current bill. Legislators expressed concerns that while New Mexico State University is actively involved in research on both brackish and produced water, the bill's language appears to prioritize brackish water projects. This shift in focus raises questions about the future of produced water research, which is already a critical area of study given the state's water scarcity issues.

One lawmaker pointed out that existing research on produced water should not be overshadowed by the new emphasis on brackish water. The apprehension stems from the potential for the strategic water supply program to limit its scope, thereby neglecting the valuable insights gained from produced water studies. This concern reflects a broader anxiety about the sustainability of water resources in New Mexico, particularly as the state grapples with increasing demands on its water supply.

The meeting also delved into the intricacies of water rights, particularly concerning deep groundwater sources. Legislators learned that water rights for sources located below 2,500 feet are not subject to appropriation, complicating the ability of treatment facilities to secure their investments. This limitation raises further questions about the viability of developing deep aquifers for water extraction and treatment, especially in light of potential competition from other facilities.

As discussions progressed, concerns were voiced about the costs associated with treating brackish water and the environmental implications of such projects. Lawmakers emphasized the importance of utilizing renewable energy sources for any water treatment initiatives, underscoring the need for sustainable practices in managing New Mexico's water resources.

In conclusion, the meeting underscored the urgent need for a comprehensive approach to water resource management in New Mexico. As the state navigates the challenges of water scarcity, the balance between advancing research on both brackish and produced water will be crucial. Lawmakers will need to address these concerns in future legislative sessions to ensure that all aspects of water resource management are adequately funded and researched, paving the way for sustainable solutions in the face of ongoing environmental challenges.
