Industrial-size concern

Louisiana's red-carpet embrace of data centers—a fast-growing roster that includes Meta, Amazon and Hut 8 near St. Francisville—is raising legitimate concerns about the water consumption those facilities demand. But the conversation has a blind spot the size of the Mississippi River.

The petrochemical industry, which has operated in Baton Rouge's backyard for more than a century, draws far more water from the aquifer that supplies EBR's drinking water. And no one is paying much attention.

Why it matters: East Baton Rouge Parish residents get their drinking water from a single source—the Southern Hills Aquifer. It produces some of the best tap water in Louisiana, requires minimal treatment and has served the region for generations. It is also under-documented, measurable stress. The biggest threat isn't the new thing generating all the headlines.

Industrial might: The numbers don't match the alarm. Commercial and industrial facilities in the Capital Region pull roughly 50 million gallons a day from the Southern Hills Aquifer. Meta's Richland Parish data center—the one drawing the most public concern—projects an average daily draw of roughly 1.5 million gallons.

• No one disputes that the petrochemical industry is the economic bedrock of the Baton Rouge region—the Greater Baton Rouge Industry Alliance tracks more than 25,000 plant and contract employees, a local payroll exceeding $900 million and a job multiplier that accounts for an estimated 60% of regional employment.
• Still, the water in the Southern Hills Aquifer—given the current rate of consumption—is a finite resource.
• ExxonMobil's north Baton Rouge chemical facility alone drew 7.3 billion gallons from the aquifer in 2020—the most recent year for which verified data is publicly available.

Political reality: Data centers are new. Novelty generates alarm. Louisiana has never been much of a petrochemical watchdog. The math, however, is the math.

History lesson: This isn't a discovery. Journalists and investigators have documented the industrial draw, the regulatory failures and the oversight collapse for years. The reporting is thorough. The public response has been more of a shrug.

• The state Legislature dissolved the agency charged with protecting the aquifer after its director was indicted for bid-rigging a metering contract—the very contract designed to track how much water industry was pulling.
• Oversight now sits with the state Department of Energy and Natural Resources, which has signaled it will rely on voluntary industrial compliance rather than hard caps.

The technology exists: The Mississippi River runs directly alongside most of these facilities. Treating river water to industrial-grade standards is not experimental—it is established engineering used across the country.

• The primary reason petrochemical plants draw from the aquifer instead is economic. Groundwater is essentially free to pump. River water requires treatment infrastructure.
• Louisiana charges industrial users roughly $10 per million gallons in aquifer pumping fees. The all-in cost to ExxonMobil for its 7.3 billion gallon draw: less than $75,000.

Here in the real world: ExxonMobil already operates this way elsewhere. Its Baytown, Texas facility—comparable in scale—operates on treated surface water drawn from the Trinity River system, not groundwater. That shift didn't happen voluntarily. Texas regulators mandated it after industrial overpumping caused measurable land sinking along the Gulf Coast.

What would Texas do? Texas is not known for hostility toward industry. It is, however, known for protecting its aquifers. The Harris-Galveston Subsidence District uses a carrot-and-stick framework—modest fees for compliant users, steep financial penalties for facilities that fail to convert to surface water. The result: Houston's massive petrochemical corridor was moved off groundwater without shutting down a single plant.

• Texas charges non-compliant facilities more than $12,000 per million gallons pumped over their allowed threshold. Louisiana charges industrial users $10 per million gallons.
• Louisiana officials frequently cite Texas as a model worth following. They tend to be selective about which parts.
• A similar framework here—even a modest one—would create the economic incentive that currently doesn't exist.

The bottom line: The Southern Hills Aquifer produces drinking water that other Louisiana communities would envy. The conversation about protecting it shouldn't start and stop with data centers.
