Cass County Treating Company
The Cass County Treating Company site (the site) is located within the southeastern city limits of Linden, Cass county, Texas, at 304 Hall Street. The 17.07-acre site is bordered by residential areas to the west and north and undeveloped wooded areas to the south and east. The company began preserving wood with pentachlorophenol (PCP) in the 1960s. In 1984, the process was switched to chromated copper arsenate. In 1986, a TWC sampling inspection documented PCP releases into a drainage ditch and spring water leaving the site. In 1987, evidence of phenolic organic contamination was documented in the groundwater monitoring wells, located downgradient to the capped surface impoundments. The Cass County Treating Company ceased operations in 1997, but its equipment continued to be leased for wood treating by a series of leaseholders.
