Redevelopment at the Site

The 100-acre United Creosoting Company Superfund site is located in Conroe, Texas. The site is about 40 miles north of Houston. From 1946 until 1972, the United Creosoting Company operated a wood preserving facility on site. Operators at the facility treated formed lumber, such as telephone poles and railroad ties. In 1977, companies developed a portion of the property that included the Tanglewood East residential subdivision and light industrial structures. After the discovery of groundwater and soil contaminated with wood treatment chemicals, EPA listed the site on the Superfund program’s National Priorities List (NPL) in 1984. Cleanup included digging up and capping soil near residences, and monitoring groundwater. The Conroe municipal water supply connects to all buildings on the site. EPA and the State cleaned up soils to residential levels. Groundwater monitoring is ongoing and the Texas Commission on Environmental Quality leads maintenance activities at the site. Residential and light industrial land uses continue at the site.
