Cass County Treating Company

This former wood treating site in Linden, Cass County, is in the remedial investigation stage of the state Superfund Program.

Site Summary

This 17-acre site is encircled by Hall Road and Shirley Drive in Linden, approximately 0.4 mile southeast of the intersection of FM1841 and U.S. Highway 59. The Cass County Treating Company treated wood from 1962 until 1997 using pentachlorophenol and chromated copper arsenate.

Superfund Registry

The property was abandoned in 2004. In February 2006, the TCEQ proposed the site to the state Superfund registry after documenting the release of hazardous substances at the site.

Beginning Cleanup

In 2007, the TCEQ conducted a removal action to dispose of contaminated storage tanks, waste drums, sumps, and their contents. The TCEQ also removed contaminated concrete and dilapidated structures that would have hindered future investigations. The remedial investigation has determined that soils and groundwater are impacted with pentachlorophenol, arsenic, and dioxins. 


The site is currently in the remedial investigation phase to determine the nature and extent of contamination at the site.
