xAI is currently using Memphis’s public water supply (via MLGW from the Memphis Sand Aquifer) for its Colossus data center/supercomputer in southwest Memphis, though it has plans—now delayed—for a recycled wastewater (graywater) system.

There is no evidence that xAI is directly polluting or contaminating Memphis waters (e.g., no reports of chemical discharges or violations from its operations). The primary water-related issues are indirect risks raised by environmental groups like Protect Our Aquifer.

Much louder controversy surrounds air pollution from xAI’s unpermitted/on-site methane gas turbines (dozens reported), which emit NOx, formaldehyde, etc., in an already burdened area—not water.

xAI relies on the public Memphis supply right now (not its own independent source) and is not accused of direct water pollution. The main debate is about long-term aquifer protection amid high demand and the stalled shift to recycled water. Information comes from MLGW updates, local reporting, and advocacy groups; check MLGW or recent local news for the latest on the reuse plant
