Stage of Clean-up: Remedial Assessment Not Begun
The Patrick Bayou site consists of contaminated sediments within the Bayou, a portion of the East Fork tributary, and associated wetlands. Patrick Bayou is one of several small bayous of the Houston Ship Channel (HSC) located within the lower portion of the San Jacinto River Basin as it enters Galveston Bay in southeast Texas. Pesticides, POLYNUCLEAR AROMATIC HYDROCARBONS (PAHS), metals, and POLYCHLORINATED BIPHENYLS (PCBS) have been detected in sediments in the Bayou since the early to mid-1990s. For several years, Patrick Bayou has received an accumulation of permitted industrial wastewater discharges, municipal wastewater treatment plant effluent, and storm water runoff from adjacent industrial facilities and nearby urban/residential areas. These discharges are suspected to be the primary sources of the sediment contamination. The site is being proposed to the NPL because sediment contamination has been detected in the wetlands bordering the Bayou and poses a threat to downstream fisheries. Patrick Bayou is located in a mixed urban, highly industrialized petrochemical area in southeast Harris County approximately 1 mile north of the Deer Park, Texas, north of State Highway (SH) 225.
