3502 ROGERDALE RD

The Crystal Chemical Site is located at 10985 Westpark Drive (formerly 3502 Rogerdale Road), in southwest Houston, Harris County, Texas. The Site spans approximately 6.8 acres and is bounded to the west by the Harris County Flood Control District drainage ditch (No. D124 - 00 - 00); to the east by the Union Pacific Railroad (UPRR) 5 - acre tract that houses the ground water treatment plant (GWTP); to the south by the Shearton Development, Inc. (She arton) tract (purchased by UPRR in November 2004), which is currently undeveloped; and to the north by Westpark Drive. Crystal Chemical produced arsenical, phenolic, and amine - based herbicides on the site from 1968 to 1981. Between 1968 and 1979, Crystal Chemical leased the 6.8 - acre tract from the owner Southem Pacific Transportation Company (Southem Pacific), now UPRR. In 1979, Crystal Chemical purchased the property. In 1981, Crystal Chemical ceased operations, filed for bankruptcy, and abandoned the sit e. With the exception of investigation and remedial activities, the site has been inactive since September 1981 (EPA 2005). The area surrounding the Crystal Chemical Site is primarily used for commercial, light industry, and residential purposes. Site cleanup has reduced health risks for over 20,000 residents living within one mile of the site. During the previous 5 - year review ( September 2005) the EPA found that the implemented soil and ground water containment system r emedies, the ongoing ground water recovery and treatment remedy, the ongoing ground water monitoring, and the site operations and maintenance activities are protective of human health and the environment
