Health department installs South Memphis air-monitoring station with EPA funds
Summary
Shelby County Health Department reported installation of an EPA-funded air-monitoring shelter in South Memphis; $304,801 of $411,000 grant spent to date, with monitoring completed for ozone and carbon monoxide in a roughly 1.5-mile radius.
Casey Smith Alexander, deputy director of the Shelby County Health Department, briefed commissioners on a new South Memphis air-monitoring site funded by a $411,000 EPA award. The department has spent $304,801 as of March 23, 2026; the installed shelter went in on Feb. 27 and remaining steps include electrical meter connection, network installation, and instrument hookups.
Alexander said the station will monitor continuous streams of ozone and carbon-monoxide data. "We're looking at a 1.5 mile radius that will actually be monitored," she said, adding extended 5.5-mile rings in the packet to show broader context but noting that concentrations vary with wind and local sources. The station will be the county’s sixth air-monitoring site and the first located in South Memphis.
Commissioners asked about coverage and whether additional monitors will be needed; Alexander said additional stations would require EPA approval but agreed the area likely needs more monitoring stations over time.
