In a recent meeting of the Water and Natural Resources Committee, significant strides were made in understanding New Mexico's brackish groundwater resources. The committee discussed a comprehensive analysis of groundwater quality, which is crucial for both environmental management and agricultural practices in the region.

The analysis involved collaboration with various stakeholders, including the Office of the State Engineer, the New Mexico Environment Department (NMED), and local farmers and ranchers. The team identified 19 sites with brackish groundwater and collected 23 water samples for detailed testing. This effort aims to characterize the groundwater and assess its suitability for various uses.

Key findings from the analysis revealed a wide range of total dissolved solids (TDS) concentrations, varying from 770 to 55,000 milligrams per liter, with an average of 8,000 milligrams per liter. This data is essential for understanding the salinity levels in different basins across the state. Additionally, the total organic carbon (TOC) levels were measured, indicating a lower presence of organic constituents in the water, which can affect its quality and usability.

The committee also highlighted the importance of analyzing emerging contaminants, particularly per- and polyfluoroalkyl substances (PFAS), which have raised concerns due to their potential health impacts. The analysis included testing for 25 PFAS compounds, aligning with federal drinking water regulations.

This thorough investigation into brackish groundwater not only enhances the state's understanding of its water resources but also supports informed decision-making for sustainable water management. As New Mexico faces ongoing challenges related to water scarcity, these findings will play a crucial role in shaping future policies and practices that directly affect the community's access to safe and reliable water sources.
