  • Site Description
    Stage of Clean-up: Construction Completed

    Conditions at listing (July 1982): The Highlands Acid Pit is located on the bank of the San Jacinto River in Highlands, Harris County, Texas. The 18-acre site appears to be an excavated sand pit in which spent SULFURIC ACID sludges from an unknown chemical process were dumped in the early 1950s. The highly acid sludge contains HEAVY METALS and organic chemicals. Strong odors emanate from the site during hot, dry weather. Contaminants have been discovered in run-off, as well as in ground water at the site. The area is subsiding, and portions of the property are under water. Status (July 1983): In September 1982, EPA awarded a $402,864 Cooperative Agreement to Texas for a remedial investigation to determine the type and extent of contamination at the site and a feasibility study to identify alternatives for remedial action. The work is scheduled to be completed in the first quarter of 1984.
