Geosyntec Team Designs Software Tool to Aid Selection of Remedies for Chlorinated Solvents in Groundwater

A team of Geosyntec engineers and scientists specializing in groundwater remediation have developed a new software tool that aids in the evaluation and selection of remediation technologies that address dense non-aqueous phase liquids (DNAPLs), often in the form of chlorinated solvents.

Using the DNAPL Technology Evaluation Screening Tool (DNAPL TEST) can help in the identification and appreciation of the optimal technology available to address plumes of chlorinated solvents at impacted sites. DNAPL TEST allows engineers and site managers to:

  • Select DNAPL remediation technologies based on desired performance metrics
  • Evaluate potential technology performance at an impacted site
  • Reduce uncertainty when estimating remedial outcomes and implementation costs

The software was developed through a collaborative effort led by Geosyntec Consultants that included student researchers at Queen's University in Ontario and the University of Edinburgh in the United Kingdom. Development of the tool was funded by the U.S. Department of Defense's Environmental Security Technology Certification Program (ESTCP) under the guidance and oversight of the Naval Facilities Engineering Services Center (Port Hueneme).

The software can be accessed from Geosyntec's website and the final report detailing the development process can be downloaded from ESTCP's website.

David Major, Ph.D., a principal engineer for Geosyntec based in Ontario, was the principal investigator for design of DNAPL TEST. He worked with project manager Julie Konzuk, Ph.D., P.Eng., an associate environmental engineer also based in Ontario. Their software development team included Geosyntec scientists and engineers Cathy Crea, Cathy Garvin, Gavin Grant, P.Eng., Donna Kuntz, Cherilyn Mertes, and Natasha Wilkie, all based in Ontario.

Additional contributors include Carmen Lebr_??_n of the Naval Facilities Engineering Services Center; Jason Gerhard, Ph.D., and his graduate student Tiwee Pang from the University of Edinburgh; and Bernie Kueper, Ph.D., and his graduate student team of Mike West, Alexandra Richards, and Keeley Mundle at Queen's University.

DNAPL TEST was developed using Microsoft Access and can be used on any computer that has Access installed.
