Sampson Horrice

No further Superfund environmental response actions are required at this former gravel pit/landfill in which hazardous & solid waste was disposed in Dallas, Dallas County.

Site Background

The Sampson Horrice site is located on two adjoining 10-acre tracts at 2000 and 2006 Plainfield Drive in Dallas. The site was formerly listed as located at 8460 Sparrow Street in Dallas. It is an inactive gravel pit that is reported to have illegally accepted solid and hazardous waste in 1983 and 1984. The gravel pit is abandoned; no buildings, equipment, or workers are present on the site. A security fence around the site was constructed in 1997. No specific information was found on waste management activities at the site; therefore, it is not known whether all or only part of the property was used for waste disposal. Trash, debris, and crushed 55-gallon drums were observed in several areas scattered throughout the site. Debris consisted primarily of construction-type materials. Allegedly, an estimated 200 to 400 drums were buried on site. In order to determine the location of trenches, pits, or individual buried drums, a magnetic survey was conducted by the Texas Natural Resource Conservation Commission (TNRCC) in February 1994. Based on the interpretation of data collected from the magnetic survey, several potential locations of trenches, pits, or possible ferrous-containing objects were identified.
