Community air monitoring project finds South Memphis is regularly exposed to unsafe air pollution

A recent report from a community air monitoring project, released on May 21, indicates that residents in South Memphis are consistently exposed to air pollution levels surpassing the U.S. Environmental Protection Agency's public health standards. The report, compiled by the Center for Engagement, Environmental Justice, and Health INpowering Communities (CEEJH INC) in partnership with Memphis Community Against Pollution, utilized PurpleAir monitors distributed to residents due to the absence of a government air monitoring site in South Memphis for over a decade.

The findings show that the average concentration of fine particulate matter at three South Memphis test sites exceeded the EPA's annual standard during all times of day from November 2023 to March 2024. This suggests a pervasive issue, with some areas like Westwood/Whitehaven experiencing levels higher than the EPA standard nearly 75% of the time. These levels remained elevated even during non-commuting hours, pointing to continuous background pollution from industrial sources, including a refinery, manufacturing facilities, power plants, and xAI's Colossus data center and its associated gas turbines.

While a Shelby County Health Department spokesperson, Joan Carr, stated that PurpleAir monitor data cannot be directly compared to EPA standards for regulatory purposes, researchers followed EPA guidelines for participatory air monitoring projects, calibrating their data against EPA-approved monitors. Vivek Ravichandran, CEEJH INC Director of Research and Policy, highlighted that the absence of "safe windows" means vulnerable populations remain at risk. The Shelby County Health Department plans to reopen a South Memphis monitoring site in June. This report represents the latest development in the majority-Black community's ongoing efforts to secure stricter pollution limits and enforcement.
