Treatment: Offsite Liquid Phase: Air Stripping & Activated Carbon (groundwater) Treatment
Vapor Phase: Electric Catalytic Oxidizer
Scope:Investigate, Remediate, Design, Build, and OperateProject Summary

  • Enviro-Sciences supported and coordinated the design of both the DPHVE system and in-situ chemical oxidation program.
  • The DPHVE system removed and treated approximately 1,480 pounds of contamination via soil vapor extraction and approximately 1,578,730 gallons of impacted groundwater.
  • An exit strategy was negotiated with the NYSDEC.
