Marshall Wood Preserving

This former wood treating facility in Marshall, Harrison County is in the remedial investigation phase of the state Superfund program.

Site Summary

The 14.5-acre Marshall Wood-Preserving site is located at the historical address of 2700 West Houston Street. The Site is located on the northeast and southwest side of Martin Luther King Jr. Boulevard (Texas Loop 390), west of its intersection with West Houston Street, in Marshall, Texas.

From approximately 1949 through 1980, Marshall Wood Preserving manufactured pressure-treated wood fencing, highway posts, pilings, and other products at the site. Soil, groundwater, surface water, and sediment are contaminated with chemicals used in the wood treating processes, including creosote and pentachlorophenol (also known as PCP).

Superfund Registry and Investigation

The TCEQ proposed the site to the state Superfund registry in September 1990 and began the remedial investigation in June 1991. TCEQ has conducted soil, groundwater, surface water, and sediment sampling to determine the nature and extent of contamination and to evaluate ecological risks associated with the release.

Current Status

The TCEQ plans on conducting a removal action at the site to mitigate two former process wastewater surface impoundments as a continuing source of releases of chemicals of concern. The site is currently in the remedial investigation phase, and the TCEQ is also conducting a feasibility study to develop and analyze potential cleanup alternatives.
