Remediation

EMC prepares Remediation Plans or Corrective Action Plans (CAP) for sites with many different types of chemicals of concern. In evaluating the various remedial alternatives for each site, the following items are considered: extent of remediation effort; technical feasibility to address the physical and chemical characteristics of the media; projected contaminant removal and treatment rates; protectiveness of human health; clean-up criteria; ability of each alternative to achieve clean-up criteria; community acceptance; anticipated volume of contaminated materials to be treated; ease of technology application or implemen-tation; dimensions of major technologies and space limitations; process parameters; clean-up time frames; transportation distances; operation and maintenance costs and any other special considerations. Each viable remedial technology is compared using some or all of the criteria described above in determining the most cost-efficient and effective remedial technology for each site. Remedial designs have included the following technologies: air sparge, soil vapor extraction, groundwater pump and treat, multi-phase extraction, free-product recovery, vacuum enhanced extraction, enhanced bioremediation using Oxygen Releasing Compounds (ORC) and microbe injections and over-excavation.

The principal objective of soil and ground water remediation is to remove the waste material and/or reduce the concentration of contaminants in the soil or groundwater to specific land use acceptable levels.

EMC has experience in design and installation of several remediation systems and treatment plans. These plans have been approved for projects in several states.
