Beneath America’s surface, a crisis is quietly unfolding. Once-reliable groundwater reserves are draining at an alarming pace. The factors driving this depletion are complex—climate shifts, unchecked consumption, and failing infrastructure all play a role. Given these intertwined challenges, urgent action is needed to safeguard water supplies across these 10 states facing groundwater depletion.
California
Decades of excessive groundwater extraction have led to severe land subsidence in California’s Central Valley. Studies from the U.S. Geological Survey highlight that aquifer recovery may take centuries without strategic intervention. To address this, the state is scaling up managed aquifer recharge efforts while strengthening conservation incentives to curb agricultural overuse.
Arizona
Arizona’s reliance on the Colorado River is proving unsustainable as climate change worsens. Water levels are reaching historic lows, threatening urban areas like Phoenix and also the agricultural communities. With increasing public awareness of these challenges, policymakers now face mounting pressure to implement stricter water usage limits.
New Mexico
The state’s aquifers are depleting faster than they can naturally replenish. Decades of drought have encouraged some farmers to adopt water-efficient irrigation systems; however, adoption remains uneven across the region. Meanwhile, community-led efforts champion wastewater recycling, although long-term sustainability ultimately depends on consistent enforcement of conservation policies.
Colorado
Shrinking snowpacks disrupt Colorado’s river flows, reducing groundwater recharge rates. Hydrologist Jay Famiglietti warns that groundwater in the Colorado River Basin is vanishing 2.4 times faster than surface water, largely due to unregulated pumping. In response, state-funded watershed restoration projects aim to mitigate these climate-driven declines, but these efforts require regulatory measures.
Nevada
Las Vegas leads the nation in urban water conservation, yet Nevada’s rural groundwater reserves are rapidly vanishing. This disconnect between urban water-use efficiency and agricultural depletion complicates policy solutions. To address these challenges, expanding sustainable land-use practices remains critical for balancing water needs across different sectors and industries.
Utah
Utah struggles with shrinking water supplies due to rapid population growth, drought, and falling reservoir and snowpack levels. High water use worsens the crisis, while the Great Salt Lake’s decline threatens ecology and economy. Some cities adopt conservation measures, but costly desalination limits large-scale solutions amid urgent groundwater depletion.
Texas
Texas aquifers face rapid declines due to ongoing drought, leading to deeper drilling and water shortages. The Edwards Aquifer Authority declared Stage 5 restrictions, cutting water use by 44% for permits and contracts in Hays County, affecting cities like Kyle and San Marcos and entities including Texas State University.
Nebraska
The state’s groundwater levels have steadily dropped, with 85% of wells showing reductions from 2022 to 2023. The High Plains Aquifer is also facing long-term declines, especially in Chase, Perkins, Dundy, and Box Butte counties. Heavy irrigation, drought, and low rainfall are driving this depletion.
Kansas
The Ogallala Aquifer, a vital water source for Kansas, is vanishing due to excessive withdrawals. According to Brownie Wilson, water data manager at the Kansas Geological Survey, a significant portion of the aquifer has reached critical depletion levels. In response, farmers are experimenting with drought-resistant crops; however, broader conservation mandates are essential.
Idaho
Although Idaho’s groundwater crisis has largely escaped national attention, the growing agricultural strain has raised alarms among local conservationists. These advocates are urging businesses to prioritize sustainable water practices to protect this vital resource. Without corporate accountability and government intervention, groundwater depletion in Idaho is likely to continue unchecked.
