MSDH Finds No Contamination of Public Water Supply in Village of Glendora Following Train Derailment

Jackson, Miss. — The Mississippi State Department Health (MSDH) has finished sampling and testing of the public water supply in the Village of Glendora and found no contamination of benzene following a Canadian National (CN) train derailment.

On July 8, 2025, the MSDH Bureau of Public Water Supply collected samples from the Glendora public water supply, located in Tallahatchie County, to test for potential benzene impacts from the derailment and spillage of benzene. CN Railroad personnel also collected samples at the same time from the same locations. The MSDH samples were analyzed by the Mississippi Public Health Laboratory, and the CN samples were analyzed by a third-party certified laboratory. The results of those analyses confirm no benzene impacts to the Glendora public water supply.

Out of an abundance of caution, and in an effort to ensure public health protection, the MSDH Bureau of Public Water Supply will temporarily increase the benzene monitoring frequency for Glendora from once every six years to annually. If no detectable results for benzene are shown for three consecutive years, the sampling frequency will return to the regulatory standard of every six years. The MSDH Bureau of Public Water Supply will continue to work alongside the Mississippi Department of Environmental Quality (MDEQ), the Mississippi Emergency Management Agency (MEMA), and CN until this event response is completed.
