Characterization and Remediation of Soil, Soil Vapor and Groundwater

Project Highlights:
  • Characterized extent of subsurface impact due to site use
  • Soil, soil vapor, and groundwater VOC impacts related to dry-cleaning process
  • Evaluated and implemented remedial technologies catered to each site’s contamination and subsurface condition.
  • Coordination of project team of attorneys, responsible parties, and consultants
  • Developed working relationships with local regulatory agencies

The client, a large property management company, retained EEC Environmental (EEC) to assess, remediate, and manage multiple sites due to EEC’s well-known expertise in remediating solvent releases at dry-cleaning facilities and in large-scale industrial volatile organic compound (VOC) releases.

As a result of the operation of dry-cleaning facilities, these sites were impacted by the chlorinated solvents used in the dry-cleaning process. The initial assessment of soil, soil vapor, and groundwater revealed that soil and groundwater were impacted with chlorinated solvents and posed an immediate vapor intrusion risk to several nearby facilities and/or residences. To remediate the sites EEC did one or more of the following:

  • On-site soil, soil vapor, and groundwater characterization
  • Design, installation, and testing of DPE or SVE systems
  • Feasibility evaluation of chemical and biological injection to treat groundwater and soil
  • Remedial excavation of “hot spots” to enhance source recovery
  • Installation and monitoring of groundwater monitoring network
  • Completion of large-scale remediation projects while allowing property tenant to continue business operations
  • On-going groundwater and soil vapor monitoring

Also, EEC proactively investigated the history of land use at these sites to determine possible additional responsible parties and determine the most cost-effective path to site closure.

EEC’s fast response to the urgent issues at these sites were successful with regard to the protection of human health and significantly reduced environmental impacts without affecting the normal business operations at the shopping center.
