Regulatory Agency: New York State Department of Environmental Conservation (NYSDEC)
Contaminants: Volatile Organics including Light Non-Aqueous Phase Liquid (LNAPL)
Remediation: Dual Phase High Vacuum Extraction (DPHVE) System and In-situ Chemical Oxidation (ISCO)
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.
Based on identified contamination associated with former underground storage tanks (USTs), a Stipulation Agreement and Corrective Action Plan were executed with the NYSDEC to address the NYSDEC Spill Case.
