Experts warn of serious health risks from xAI power plant in Southaven

Concerns are escalating over a proposed 1.2-gigawatt power facility in Southaven, Mississippi, intended to support an xAI data center, with researchers and community leaders warning of substantial health and environmental repercussions for the broader Memphis area. A town hall meeting at The Healing Cathedral Christian Church in Memphis brought together residents, State Rep. Justin J. Pearson, and Harvard University environmental health scientist Michael Cork to discuss these potential risks. Michael Cork presented research indicating that the proposed facility would emit fine particulate matter (PM 2.5), which can deeply penetrate lungs and enter the bloodstream, leading to serious conditions like heart attacks, strokes, asthma, and premature death. He stressed that there is no safe level of long-term exposure to PM 2.5, and warned that emissions would not respect state borders, potentially affecting communities such as Whitehaven in Memphis, and Horn Lake, Westwood, and Southaven in Mississippi. Cork's analysis also projected that older populations and majority Black communities would be disproportionately affected, estimating annual health-related damages could range from $30 million to $44 million, accumulating to $600 million to $840 million over 30 years. State Rep. Justin J. Pearson urged attendees to pressure local and state leaders for more rigorous oversight and accountability, stating, "We’re in a fight to be alive." Community members at the town hall questioned the approval process for temporary turbines associated with the project and raised broader concerns about long-term air quality and quality of life. Both Pearson and Cork emphasized the critical need for independent, science-based analyses to fully understand the impact of large-scale data centers and associated power infrastructure on the region.
