EPA begins environmental testing at Union Pacific site in Houston, Texas
What happened
The Environmental Protection Agency began expanded environmental testing at a Union Pacific Railroad site in Houston's Fifth Ward, Texas, on November 9, 2026. The testing addresses contaminants from a former wood-preservation facility that operated from 1911 to 1984 and used creosote, which has been classified as a probable carcinogen. The EPA and Union Pacific Railroad have completed a health risk assessment based on the soil testing, but the draft report has not been released.
Why it matters
The testing relates to a facility where state officials have identified cancer clusters near the site. The ongoing regulatory action and potential findings could trigger environmental liability and remediation costs for Union Pacific Railroad. Residents are calling for the Environmental Protection Agency to release the results of its report.
