Contaminants:
Chlorinated and Non-Chlorinated Aliphatics and Semivolatile Organic Compounds - Concentration of specific volatiles ranged as high as 1,200 mg/kg in source area soils - Concentration of specific semivolatiles ranged as high as 1,800 mg/kg in source area soils |
Waste Source:
Underground Storage Tank; Other: Leaching Pool |
Type/Quantity of Media Treated:
Soil - 1,250 cubic yards of soil treated in this application - Well-sorted sands to silty sands with fine gravel - Permeability 0.00227 to 0.00333 cm/sec |
Purpose/Significance of Application:
Full-scale SVE system that used horizontal vapor extraction wells and a process control system which allowed for remote system monitoring and oversight. |
Regulatory Requirements/Cleanup Goals:
- Soil cleanup levels established for 9 volatiles and 9 semivolatiles; levels ranged from 0.5 to 5.5 mg/kg - Additional criteria specified for soil cleanup effort based on percent reductions - Air emissions required to meet New York State ambient air guidelines for toxic air contaminants |
Results:
- Soil cleanup levels and criteria were achieved within approximately 400 days after system operation began |
Cost Factors:
- Total treatment system cost was $450,520 (including $182,700 for one year of monthly operation and maintenance, mobilization, system design and construction, demobilization, drum relocation) |
Description:
The SMS Instruments site in Deer Park, NY was used for overhauling military aircraft components. Past waste disposal practices at the site included discharging untreated wastewater from degreasing and other refurbishing operations to an underground leaching pool. In addition, jet fuel was stored at the site in an underground storage tank. The results of a Remedial Investigation at the site indicated soil contamination in the areas of the leaching pool and the underground storage tank. Contaminant concentrations in soil ranged as high as 1,200 mg/kg for volatiles and 1,800 mg/kg for semivolatiles. The New York Department of Environmental Conservation developed soil cleanup levels for 9 volatile and 9 semivolatile constituents.
Soil vapor extraction (SVE) was used at SMS to treat the contaminated soil.
The SVE system, operated from May 1992 to October 1993, included two horizontal vapor extraction wells installed in trenches adjacent to the contaminated areas, a catalytic oxidizer, and acid gas scrubber. Based on the results of soil boring data, collected in June 1993, SVE achieved the cleanup levels and standards for 17 of the 18 specified organic constituents. For one constituent, BEHP, concentrations were above the specified cleanup level. However, according to the EPA RPM, this result may be an anomaly since the concentration of BEHP in the treated soil was greater than concentrations of BEHP identified during the remedial investigation at the site. In addition, the state ambient air guidelines were met during the operation of this system.
The total treatment cost for this application was $450,420. The treatment vendor indicated that the costs associated with instrumentation were greater than anticipated and that there was a problem with corrosion of ductwork. The vendor suggested several ideas for reducing costs of future similar applications including ways to reduce air monitoring costs. |
