*ERH is adaptable to all soil types and sedimentary bedrock.  ERH is also effective in both the vadose and saturated zones.  Certain lithologies can limit traditional methods of remediation by preventing a reliable removal/destruction pathway for the contamination of concern. Because electricity can and does travel through any lithology that contains some water, ERH can be effective in any soil type. By forming buoyant steam bubbles during the heating process, ERH creates a carrier gas that transports the contamination of concern up and out of any soil type. ERH is not capable of desiccating the subsurface.  In order for the subsurface to conduct electricity, there must be water present in the subsurface.  Conductivity will cease before the subsurface is desiccated.
*ERH is commonly applied under active buildings or manufacturing facilities.  Electrodes can be installed above grade within a fenced area or below grade to allow for unrestricted surface access to the treatment area.
*Although principally used for contaminant source areas, ERH can be used to achieve low remedial goals such as maximum contaminant levels, MCLs, for drinking water.
*After ERH treatment, elevated subsurface temperatures will slowly cool over a period of months or years and return to ambient.  This period with elevated temperatures is an important part of the remediation process.  The elevated temperatures will enhance Bioremediation, hydrolysis and iron reductive dehalogenation.
