• GULFCO MARINE MAINTENANCE, BRAZORIA County, TX

Stage of Clean-up: Remedial Assessment Not Begun

Conditions at Proposal (September 5, 2002): The Gulfco Marine Maintenance (Gulfco), facility encompasses 40 acres in Freeport, Brazoria County, Texas. The facility historically was used as a barge cleaning and servicing facility. The Gulfco site encompasses three buried/backfilled surface impoundments that received contaminated wash water from the barge cleaning operations, areas of contaminated soil, and releases to surface water and ground water. The site is being proposed to the NPL based on evidence that hazardous substances, including semivolatile organic compounds, lead, zinc, and pesticides, have migrated from the facility to the Intracoastal Waterway, pose a threat to nearby drinking water supplies and downstream sensitive environments, and have impacted fisheries downstream of the facility. Gulfco operated as a barge cleaning and waste disposal facility from 1971 through 1979. Operations at the facility involved the cleaning, servicing, and repair of various chemical barges. Chemical barges were drained and pumped to remove product heels, which then were stored in tanks and sold as product. Each barge was washed with water or a detergent solution. Generated wash waters were stored either in surface impoundments, a floating barge, or on-site storage tanks. The barges were allowed to air dry and certified as safe prior to initiating repair work such as welding and sandblasting.  More...
