OPINION: Groundwater report serves as a call to action

As leaders in New Mexico’s water community, we remain alarmed by our ongoing water crisis, particularly when it comes to groundwater. That’s why we’ve been working with the New Mexico Groundwater Alliance to conduct a comprehensive review of our groundwater situation and offer recommendations for policymakers to advance more proactive statewide groundwater management.

This week, we released our 360 Groundwater Report, which confirms a dire situation: Our aquifers are plunging to historically low levels as a result of challenges like drought, climate change, water-hungry data centers and PFAS contamination.

The stakes are high, as groundwater provides more than half the state’s total water supply, with 81% of public water systems relying on groundwater for drinking water.

Fortunately, our report offers solutions, which many local communities are already implementing. Key among them is more groundwater mapping, monitoring and metering. Thanks to the leadership of House Appropriations and Finance Committee Chair Nathan Small, D-Las Cruces, New Mexico has made progress investing in these common-sense, scientific tools. But in the case of metering — the process of tracking how much groundwater is being pumped — we’ve rarely used some of these tools unless threatened by legal action.

As a result, and as our report details, the majority of New Mexico’s wells are not metered. This means we don’t know what’s being pumped out of our aquifers and limits our ability to effectively manage our shared groundwater supplies. After all, you can’t manage what you don’t measure.

Thankfully, we’re seeing progress in some communities, whose lessons learned can be applied to other areas.

Take for instance the Pecos Valley Artesian Conservation District in Chaves and Eddy counties, whose water users have had their wells metered for decades to avoid priority calls from neighboring districts.

In the Lower Rio Grande, water users were required to meter their wells starting in the 2000s under a metering order, providing the data essential to settling the Supreme Court litigation in the basin.

In Curry County, where groundwater levels have plunged dangerously low, no state metering order is in place. Therefore, the Ogallala Land & Water Conservancy created a voluntary, market-based model to conserve finite groundwater supplies. Metering is the heart of this work, helping farmers receive compensation for leasing a portion of their water rights to create a more sustainable aquifer for future generations. Thanks to the proactive leadership of landowners, more than 4 billion gallons of water a year have been saved.

In each of these cases, while metering was not popular at first, landowners eventually came to embrace it as a system in which they could be confident everyone was playing by the same rules. These examples demonstrate the value of metering that can be replicated statewide. In the Middle Rio Grande, a metering order by the Office of the State Engineer could be imminent and is necessary to avoid further lawsuits that are expensive and burdensome.

In the end, it all comes down to having reliable data to inform difficult decisions. Our agencies and local district managers need the tools and resources to leverage 21st century technology so they can better develop locally led, proactive solutions to reduce groundwater pumping and return their water sources to healthier levels.

Our 360 Groundwater Report serves as a call to action to protect New Mexico’s groundwater before it’s too late. We hope it will also be a launching point to elevate the urgency of groundwater depletion and develop a more long-term, well-funded and proactive statewide strategy for future generations.
