After months of reporting and community concern, the city of Memphis has released its findings of air quality testing that took place near xAI’s two data centers. The PDF of those results can be seen here, and for more, we turn to Samuel Hardiman:
The city tested at Macedonia Missionary Baptist in Boxtown, which is near xAI’s first Memphis data center; The Links at Whitehaven, located near xAI’s second Memphis data center, and City Hall. Both xAI facilities as well as the nearby locations tested are also close to the Tennessee Valley Authority’s natural gas plants, which also emit pollutants.
There are no air-monitoring stations anywhere near either xAI facility, so it is not clear how air-quality levels have changed in time and what the levels of chemicals were before xAI arrived in Memphis. The results are for just two days: June 13 and 16.
In a press release, the city outlined the results:
The testing was conducted by an independent, accredited laboratory and targeted key pollutants known to impact public health, including benzene, toluene, formaldehyde, nitrogen dioxide, sulfur dioxide, carbon monoxide, and particulate matter.
The findings were definitive and reassuring.
At every site and for every pollutant tested, levels were either too low to detect or well below established safety thresholds. Only one sample – formaldehyde at City Hall on June 13 – slightly exceeded the lab’s Limit of Quantitation (LOQ), yet even that result remained far beneath any level of health concern.
City officials emphasized that while this initial data provides important insight, it represents only a snapshot in time. Continued monitoring is planned, and future results will be made publicly available.

This testing was clearly limited in scope, but is encouraging. In a statement released to press outlets — including 512 Pixels — xAI said:
xAI welcomes the independent third-party data showing no dangerous pollutant levels at test sites near our Memphis data center. We have built a world-class data center in Memphis and we couldn’t have done it without the support of the local community and its leaders.
The Southern Environmental Law Center, which is preparing to sue xAI, pushed back on the results, according to Hardiman:
Not everyone welcomed the results. SELC said the city’s release of the results was misleading and failed to take into account some smog-causing chemicals the city tested in nearly enclosed spaces and didn’t take wind into account.
“The city’s flawed air quality analysis creates a misleading narrative that serves as a distraction from the air pollution problems that Memphians face every day,” SELC’s Patrick Anderson said in a statement.
I hope that the city — and other groups — continue to test air quality around all of the data centers that are springing up around the “Digital Delta.” This will continue to be an important issue, especially once xAI’s massive second site comes online.
