Thermal Desorption Technology of Choice for CWA Remediation

The Joint Project Manager for Elimination (JPM-E) is evaluating the technologies to remediate chemical warfare agent (CWA) contaminated soils and debris on site at large chemical weapons burial sites.

The project will consist of three phases. The first phase will be the selection of a technology. The second phase will be the award of a contract to test the technology. The third phase will be the execution of the test. The test will evaluate technology performance with several parameters to include soils types, agent contamination, and moisture content of the soils.

The project consists of three phases. The first phase is the selection of a technology. Based on a recent evaluation of submitted vendor capabilities and other market research, the JPM-E has determined to select Thermal Desorption technology for conducting future testing in Phase 2 and 3 of the effort.

Thermal Desorption (TD) was chosen based on the following reasons:

  • Proven technology that can meet all of the stated criteria
  • This mature technology has been permitted and used at over 70 Superfund sites
  • Thermal desorption has been used for over 30 years to remediate soils
  • Widely accepted for remediation of hazardous materials in soils
  • Related equipment is mobile and transportable
  • Can be operated through a wide temperature range 300-1,000F
  • Equipment is scalable and can designed and operated at multiple through put rates
  • Adaptable to operate with chemicals in the feed (dehalogenation)
  • Can be operated with various treatments of the vapor stream

JPM-E additional reports that there are over 39 vendors for Thermal Desorption remediation listed in EPA’s Remediation and Characterization Innovative Technologies database (EPA REACH IT) the largest number of vendors for any technology. The large number of vendors will help to promote full and open competition.

The second phase will be the award of a contract to test the technology. The third phase will be the execution of the test. The test will evaluate technology performance with several parameters to include soils types, agent contamination, and moisture content of the soils.

Now that a technology type has been chosen, JPM-E will initiate the planning for competitively soliciting the testing of the selected technology, via a request for proposal, expected within the May-Jun 2015 timeframe.

Further details are available via Solicitation Number: W52P1J15R0077.
