Even earlier than an Elon Musk-owned synthetic intelligence firm opened an information middle in southwest Memphis, Tennessee, air air pollution was so unhealthy that residents of a nearby neighborhood had been much more prone to get cancer from industrial air pollution than common Individuals. Our evaluation discovered that air air pollution obtained solely barely worse because of the info middle.

The xAI Supercluster began operations on Sept. 1, 2024, powered by natural gas turbines that began operating before the company applied for the required air pollution permits. As environmental health researchers on the College of Memphis, we had been instantly involved concerning the potential for the generators to pollute the air much more and determined to analyze.

Combustion from pure gasoline generators releases a fancy combination of pollution, together with tremendous and coarse particulate matter, nitrogen dioxide, sulfur dioxide and hazardous chemicals corresponding to benzene, toluene, ethylbenzene and xylenes. Every of those compounds has been linked to severe well being penalties, corresponding to respiratory and cardiovascular sicknesses, neurological results, cancers and elevated mortality charges.

Southwest Memphis is house to predominantly Black individuals with low incomes. Native residents had been involved that the brand new knowledge middle would worsen long-standing problems of industrial pollution of their neighborhood, which incorporates ranges of tremendous particulate matter, typically referred to as PM2.5, which have lengthy been at or close to the extent the U.S. authorities says is the maximum allowable concentration.

There have been, and nonetheless are, no permanent air-quality monitors working within the neighborhoods of southwest Memphis which are closest to the xAI knowledge middle. So we developed an strategy that mixed a number of varieties of measurements and calculations to find out what air air pollution was like within the space earlier than the info middle opened, and what, if something, modified after it was up and operating.

Examining multiple pictures

We focused on two neighborhoods: the Boxtown Subdivision, located 2½ miles (4 km) east of xAI, which is the community closest to the facility, and the Riverview Subdivision, 6.8 miles (11 km) northeast, a known air pollution hot spot close to a number of industrial and site visitors emissions sources.

To create an image of native air high quality, we checked out three parts. Utilizing company-provided technical particulars concerning the generators and details about what number of had been operating at anybody time, we examined how emissions move through the air in the local area. We checked out satellite tv for pc knowledge exhibiting fine-particle air pollution each earlier than and after the generators started working. And we checked out knowledge on present air air pollution ranges in Boxtown utilizing a third-party firm’s screens on the bottom.

The corporate reported to county well being officers that the generators would emit completely different quantities of 11 completely different pollution, together with 30 tons of sulfur dioxide and 94 tons per 12 months of carbon monoxide. Utilizing a computer model recommended by the U.S. Environmental Protection Agency, we calculated how that air pollution would unfold throughout the neighborhoods.

Our calculations discovered that the xAI generators would contribute minimally to ambient air air pollution in each neighborhoods. We additionally calculated that concentrations of sulfur dioxide, carbon monoxide and nitrogen dioxide would stay nicely beneath nationwide requirements.

Fine particulate matter

The modeling estimated that fine particulate matter would increase about 1% – though that increase would come on top of a level of fine particulate matter pollution that was already higher than the national limit.

We launched our initial findings, based mostly on the pc modeling of company-reported emissions, in March 2025. Since then, our findings have been confirmed by extra analysis involving direct measurements of air high quality within the space.

To look at whether or not the xAI generators had, actually, elevated tremendous particulate matter concentrations, we in contrast satellite tv for pc measurements from earlier than and after Sept. 1, 2024. The comparability confirmed no important adjustments.

As well as, an impartial accredited lab carried out a two-day monitoring marketing campaign in June 2025. Its findings confirmed that our mannequin’s predictions for tremendous particulate matter, carbon monoxide, nitrogen dioxide and formaldehyde aligned closely with observed concentrations.

Limitations remained, nevertheless: The lab’s monitoring methods had been not sensitive enough to detect trace levels of benzene, toluene, ethylbenzene, xylenes or sulfur dioxide. That makes it unimaginable to straight examine our mannequin and real-world knowledge for these pollution.

A long-standing concern

Our analysis offers evidence that at least as of when we did our work, xAI’s natural gas turbines had not measurably degraded air quality in the surrounding neighborhoods. That said, any changes to the equipment used to generate power would likely change the data center’s emissions. And all our analyses assumed regular, normal turbine operations: Malfunctions or accidents can lead to emissions of excessive quantities of air pollutants until they are fixed or resolved.

Our findings confirmed that fine particulate matter has long been, and remains, a concern in the area. If we had access to sustained, community-based monitoring data, we could more clearly examine pollution levels and their public health effects in the community. We believe this type of monitoring by regulatory agencies and public health groups would be beneficial to the people of southwest Memphis, whether or not there is an xAI data center operating there.

Through our work, we aim to not only clarify the air pollution effects of a specific facility, but also highlight the importance of sustained scientific engagement in communities disproportionately affected by industrial emissions. By understanding and documenting the environmental health challenges faced by the residents of southwest Memphis, we hope to contribute to their ultimate mitigation.
