Chlorinated Aliphatics, Pesticides, Polynuclear Aromatic Hydrocarbons (PAHs), and Metals - VOCs up to 0.14 ppm - SVOCs up to 130 ppm - 4,4'-DDT ranging from 0.11 ppm to 8.2 ppm - Lead ranging from 26 ppm to 1,100 ppm

Waste Source:
Storage-Drums/Containers; Waste Treatment Plant

Type/Quantity of Media Treated:
Soil - Approximately 12,800 tons treated - 12-25% moisture; pH of 1-2 for some feed soils

Purpose/Significance of Application:
This application is notable for treating soils with a wide range of pH and moisture conditions.

Regulatory Requirements/Cleanup Goals:
Soil - Numeric cleanup goals identified for 11 constituents, including PAHs, pesticides, dioxin, benzene, and chlorinated aliphatics; cleanup goals ranged from 0.99 to 3,244 ~g/kg - Air - Total Dioxins/Furans: <30 mg/dscm, particulates: 0.015 gr/dscf, and four other stack gas emission parameters

Soil - Cleanup goals for all constituents were met in all soil piles tested; 6 of 11 constituents removed to levels at or below detection limit Air - Stack gas requirements met for dioxin/furan emissions and particulates

Cost Factors:
No data available

Pristine, Inc. performed liquid waste disposal operations at the site from 1974 to 1981. Spills and on-site disposal of treated wastes led to soil contamination. Soils at the Pristine site were contaminated with volatile and semivolatile organics, polynuclear aromatic hydrocarbons (PAHs), pesticides, and metals. The soils also contained greater than 2% of elemental sulfur. This application was notable for treating soil with a wide range of pH and moisture conditions.

SoilTech's 10 ton/hr mobile Anaerobic Thermal Processor (ATP) system was used for treating the contaminated soil at the Pristine site. The SoilTech ATP system included a feed system, the ATP unit (rotary kiln thermal desorber), a vapor recovery system, a flue gas treatment system, and a tailings handling system. Wastewater from the vapor recovery system was treated in an on-site wastewater treatment system. The ATP system was operated at the Pristine site from November 1, 1993 until March 4, 1994 and was used to treat approximately 12,800 tons of contaminated soil.

The ATP System treated contaminants in soil to levels below the cleanup goals. Levels of 6 of the 11 target constituents were reduced to concentrations at or below the reported detection limits. All stack gas air emission performance standards were met in this application, with occasional spikes of THC over the 20 ppm performance standard. Average throughput was approximately 6.5 tons/hr, and average on-line availability was approximately 62 percent.
