Brio Superfund site, Environmental cleanup site in Harris County, Texas.

The Brio Superfund site is a 58-acre parcel south of Houston containing former chemical processing plants and storage ponds along Mud Gully creek. The area remains fenced and access-restricted while groundwater underneath undergoes continuous monitoring for contamination.

Chemical companies operated on the site from 1957 to 1982, processing copper and petroleum before Brio Refinery Inc. went bankrupt. The closure revealed the extent of soil damage caused by decades of chemical handling at the location.

The nearby South Bend residential community was relocated after residents reported health problems connected to contamination. This relocation reflects how industrial operations at the site directly affected people's lives and wellbeing.

The site is not open to the public and can only be viewed from its perimeter. Visitors should note that this is an active remediation area where any closer approach is unsafe and prohibited.

The case resulted in a 207 million dollar settlement in 1992 and became a turning point for environmental liability enforcement in the United States. This litigation influenced how similar contamination cases were handled afterward.
