Concerns over the safety of brackish water use in New Mexico's water supply took center stage during the Water and Natural Resources Committee meeting on August 20, 2025. A committee member raised critical questions about the ecological and public health risks associated with the state's heavy investment in brackish water technology, emphasizing the need for stringent safeguards.

The discussion highlighted the uncertainty surrounding the effectiveness and safety of brackish water treatment methods, particularly reverse osmosis and brine processes. The committee member expressed apprehension about overpromising on a technology that is still evolving, noting that while El Paso has successfully integrated brackish water into its drinking supply for nearly two decades, the science behind these methods continues to develop.

In response, the Secretary assured the committee that all requirements from the New Mexico Environment Department (NMED) and the state engineer would be met before any brackish water development occurs. This commitment aims to ensure that public health remains a top priority as the state moves forward with its strategic water supply program.

The conversation underscored the importance of ongoing research and monitoring to address the potential risks associated with this relatively new technology. As New Mexico navigates its water challenges, the committee's focus on safety and public health will be crucial in shaping future water policies.
