If we don't have them, they're gonna go somewhere else,'\" said Commissioner Maria Marino, the lone dissent.\n\"And and if I were to be voting today, I would vote yes. And you can all throw, sling arrows at me, that's okay. But I think with all the conditions that were put in place and all the conditions that were agreed to, the staff did their job.”\nThe county staff approved the project and provided technical conditions that would need to be met before construction, despite the county's Zoning commission voting 7-0 against the project.\nWater and the environment\nNot being able to pin down the monthly usage of water poses difficulty for any new AI data center application seeking future approval.\nWater experts like Dr. Frederick Bloetscher — a civil, environmental and geomatics engineering professor at Florida Atlantic University — broke down the massive toll these facilities can place on the water supplies, the electric grid and the Everglades.\nBloetscher said the often-recited “100,000 gallons of potable water a day” is an underestimation, because large-scale AI data centers often use up to millions of gallons a day.\nREAD MORE: 'Not compatible': Palm Beach County rejects controversial Project Tango AI data center\nAccording to him, hyperscale AI data centers typically consume anywhere between 1 million to 5 million gallons of water a day.\nHe warns that continuously extracting millions of gallons of water to protect data center servers from overheating diverts water away from the regional flow, reducing the supply available to recharge local aquifers and support the Everglades ecosystem.\n\"We rely on the Everglades to recharge our aquifer,\" Bloetscher explained. \"More water there is more water for us. But if you're starting to pull it out, that means water's being moved out of the Everglades... and water's not available as it moves towards the coast.\"\nBecause the proposed AI data center was slated to sit next to sensitive regional water infrastructure, critics feared its water consumption and discharge could disrupt or contaminate local drinking supplies.\nFollowing the fierce debate, many residents wondered why local water authorities who own land near the site remained quiet.\nThe rule is simple: no application from an AI data center means no action, according to a statement to WLRN from the South Florida Water Management District (SFWMD). Water regulators must legally stay neutral until a project officially requests a permit to use groundwater or surface water for data server cooling.\n\"Any application must provide a water conservation plan and evaluate if the use of reclaimed water is environmentally, technically and economically feasible,\" SFWMD said. \"The land use for any data center project must be compatible with local government zoning regulations and the comprehensive plan.\"\nState laws meet local realties\nUnder Florida’s Senate Bill 484, regulators are equipped with sharper teeth, requiring public hearings and blocking permits if a project threatens local water resources.\nThe governing board of SFWMD told WLRN they are also required \"to hold a hearing before issuing a water use permit for a large-scale data center.”\nData centers must prove their operations will not deplete neighboring wells, local farms or public drinking supplies.\nEven so, Bloetscher cautions that the effectiveness of the law lives in the details.\n\"The legislation says, 'Don't do harm,'\" Bloetscher said. \"Somebody's got to write rules to define what that is... The question then is, how does it get implemented at the local level? And again, this is where it's gonna be different in different places.\"\nSuggested solutions\nBecause the Project Tango denial was issued without prejudice, the developers retain the legal right to revise their cooling logistics and submit a fresh application.\nTo safely handle future interest, Bloetscher argues that local municipalities must lock in strict regulations addressing two major vulnerabilities.\nFirst, Bloetscher suggest forcing developers to use treated wastewater for cooling instead of tapping directly into public drinking supplies.\nAnd second, developers need to figure out how all that concrete on the data center campus is going to handle heavy rainstorms so it doesn't end up flooding nearby neighborhoods.\nCommissioner Maria Sachs suggest placing hyper scale AI data centers near military installations that are far removed from residential communities — and ideally not in Palm Beach County.\n\"We have many military installations that have undeveloped land next to them that have all these sources of power, so they don't have to be in Palm Beach County,\" she said.\nMilitary bases often get priority electric grid access with dedicated lines and heavy backup power, which are ideal for heavy AI workloads. It's part of a nationwide debate on national security, according to a Politico investigative report, \"The Pentagon wants to build data centers. Congress would like a word.\"\n\"They [Project Tango owners] don't have to be right next to a beautiful community of Arden with so many students and children close to that school, which would be so close to the data center,\" Sachs said.","image_url":"https://npr.brightspotcdn.com/dims4/default/5055ccf/2147483647/strip/true/crop/1356x712+0+245/resize/1200x630!/quality/90/?url=http%3A%2F%2Fnpr-brightspot.s3.amazonaws.com%2Fea%2Fae%2F7dff969b452db8e576f6f20dca22%2Fscreenshot-2026-01-08-at-5-10-01-pm.png","lang":"en","published_at":"2026-07-30T10:00:00+00:00","fetched_at":"2026-07-30T11:15:08+00:00","status":"read","starred":0,"extract_state":"ok","summary_auto":"Following months of intense community pushback and a high-stakes county vote blocking the proposed $2 billion Project Tango AI data center expansion in Loxahatchee, tech companies are showing no signs of backing away.

If we don't have them, they're gonna go somewhere else,'\" said Commissioner Maria Marino, the lone dissent.\n\"And and if I were to be voting today, I would vote yes. And you can all throw, sling arrows at me, that's okay. But I think with all the conditions that were put in place and all the conditions that were agreed to, the staff did their job.”\nThe county staff approved the project and provided technical conditions that would need to be met before construction, despite the county's Zoning commission voting 7-0 against the project.\nWater and the environment\nNot being able to pin down the monthly usage of water poses difficulty for any new AI data center application seeking future approval.\nWater experts like Dr. Frederick Bloetscher — a civil, environmental and geomatics engineering professor at Florida Atlantic University — broke down the massive toll these facilities can place on the water supplies, the electric grid and the Everglades.\nBloetscher said the often-recited “100,000 gallons of potable water a day” is an underestimation, because large-scale AI data centers often use up to millions of gallons a day.\nREAD MORE: 'Not compatible': Palm Beach County rejects controversial Project Tango AI data center\nAccording to him, hyperscale AI data centers typically consume anywhere between 1 million to 5 million gallons of water a day.\nHe warns that continuously extracting millions of gallons of water to protect data center servers from overheating diverts water away from the regional flow, reducing the supply available to recharge local aquifers and support the Everglades ecosystem.\n\"We rely on the Everglades to recharge our aquifer,\" Bloetscher explained. \"More water there is more water for us.
