1 MI E OF FM563/7 MI N OF I-10

The Petro-Chemical Systems, Inc. Superfund Site (Site) is located on County Road 126 or CR 126 (previously known as Frontier Park Road or FPR), south of Liberty (east of Houston and FM 563; 7 miles north of I-10), Liberty County, Texas. CR 126 traverses the site. Site operations commenced prior to 1970 and continued until the late 1970s. Waste oils were dumped on CR 126 and into unlined waste pits along road. A conditional commercial permit was issued in 1971 but was revoked due to legal action and withdrawn in 1974. After 1974, the land was developed and subdivided into residential properties. In 1986, EPA installed a fence and conducted site sampling. In 1988, CR 126 was excavated, back-filled, and re-built; residents were relocated during this period. The site is characterized by recent alluvial deposits, which overlay Texas Coastal Plain deposits. The water table is at 18 to 25 feet below the surface of the site. The east end of the site falls within the 100- year flood plain along the Turtle Bayou tributary. There are residences and drinking water wells within a one-mile radius of the site along FM 563 and CR 126. However, drinking water wells currently used on the site are screened in the deeper non-contaminated aquifer at depths of approximately 180 feet or more.
