Historical operations at the Union Pacific Railroad site at 4910 Liberty Road resulted in soil and groundwater contamination. The Texas Commission on Environmental Quality reviews, approves, and conducts oversight of investigations and cleanup at the site.
In April 2019, the community group, IMPACT, expressed concerns about the health impact of living in proximity to the contamination.
In November 2019, the Houston Health Department learned that an analysis conducted by the Texas Department of Health and Human Services found elevated counts of cancers known to be associated with the kinds of chemicals of concern found at the UPRR site.
Although the site is the jurisdiction of the Texas Commission on Environmental Quality and not the Houston Health Department, the health department is taking steps to fill in gaps to address community concerns.
