Site Background:

The Cox Road Dump site in Dayton also known as Liberty Waste Disposal Company was operated as an industrial waste disposal facility from 1969 until 1983. The landfill is 83 acres on the west side of County Road 491 (Cox Road) about one mile north of FM 1413. The site was originally used to landfill tank bottoms and filter cake from petroleum companies, using a trench and fill method. The trenches used to dispose of the wastes were originally 18 to 20 feet deep and penetrated the shallow water-bearing zone. The water level was documented at 13 to 15 feet below ground surface. When industrial solid waste regulations became effective in 1970, the landfill operations were limited to a depth of 8 feet and a landfarm operation was initiated. At the close of operations, the landfill was capped with soil dug up from a portion of the site. Since then, the three-foot layer of topsoil has been eroded and the buried waste has been exposed. Runoff from the site drains into the Trinity River through a series of ditches that criss-cross the property. Analytical results of soil and water samples indicate the presence of arsenic, barium, boron, chromium, lead, and mercury. Also detected were Aroclor 1016, cadmium, cobalt, cyanide, phenol, toluene, xylene, and the pesticide 4,4-DDE.
