Dry Cleaner Remediation (ERH) – White Paper

July 9th, 2013

Electrical Resistance Heating  Small Site RemediationDry Cleaner Remediation

Electrical Resistance Heating (ERH) is an aggressive in situ remediation technology that can simultaneously remove chlorinated solvents from vadose and saturated soil. It can treat pools of dense nonaqueous phase liquids (DNAPL) found deep below the groundwater table and clean flowing aquifers. ERH systems have quickly cleaned acre sized source areas to depths of over 100-feet below grade. The technology is robust enough to return highly contaminated groundwater to drinking water quality.
Developed for US Department of Energy sites, a large ERH system applies high voltage utility-line power to electrodes placed in a grid pattern across an impacted site. As the subsurface resists this flow of electricity it is heated to the boiling point of water producing steam and contaminant vapors. These vapors are then collected just above the heated zone and treated.

Dry Cleaner Remediation

However, not all chlorinated hydrocarbon impacted properties are multi-acre Superfund sites. Many are former dry cleaner sites with small, but persistent, source areas.  They require Dry Cleaner Remediation.  Currently, no In Situ Thermal Remediation (ISTR) vendors configure their technologies specifically for the treatment of these dry cleaner remediation sites.

Global Remediation Solutions (GRS) is a national provider of ERH ISTR technology and services. We manufacture our own custom ERH equipment and can match it to any site configuration. We have developed a Small Sites Program specifically for the remediation of small chlorinated and fuel hydrocarbon source areas. Our program is based upon the following key concepts:

  • Competitive pricing based on a project life cycle costing.
  • Safe, green remediation technology providing no rebound.
  • Fast and complete remediation.  Clean-up goals met in months, with NFA letter 12 months later.
  • Mobile, customized compact ERH delivery systems requiring 440/480 electrical service.
  • Drilling and electrode designs and applications to maximize access, minimize cost, and provide full commercial use of properties during clean-up..

GRS would be happy to review any size project for the use of ERH for your Dry Cleaner Remediation.

ERH-Fast and complete chlorinated solvent clean-up.

June 15th, 2013

GRS Trailer 038 smallIn Situ Electrical Resistance Heating (ERH) is the most effective and efficient technology for the complete remediation of chlorinated solvents. Reaching clean-up goals in months, ERH addresses contaminated soil and groundwater with no rebound. ERH applications include both industrial and commercial sites, from large source areas to small dry cleaners.

Chlorinated solvents, such as PCE, TCE and their degradation products, persist in the subsurface because of their unique chemical and transport properties. After decades of operation, groundwater pump and systems have produced few, if any, site closures for these compounds. This leaves site owners with both persistently impaired property and on-going operation and maintenance costs.

ERH provides property owners a proven, fast, and complete remediation option that enables them to sell impacted property at full value or return it to productive use. The value produced by a quick and certain clean-up can be substantial for many properties.

GRS technical professionals can help you determine if ERH is a viable solution for your next remediation project. Because site conditions and contaminant parameters vary for every project, it’s best to start a dialogue early in the RI/FS process to determine if ERH is a fit for your site. We can also work with your staff to evaluate heat-enhanced bioremediation and heat-enhanced in situ chemical oxidization (ICSO).
