When is it appropriate to consider the TRS ERH Process for site remediation?
The TRS ERH Process is unfazed by low permeability or heterogeneous soil, unsaturated or saturated conditions, or by concentrations indicative of DNAPL. Thus, ERH is especially applicable for sites that would be difficult to remediate by other means. The TRS ERH Process is commonly deployed on sites where other in situ technologies were not able to complete the contaminant remediation usually due to high concentrations of contaminants and/or low permeability lithologies. When the following project and site metrics exist the TRS ERH Process usually becomes the most attractive in situ remedial technology: • You want to remediate soil and groundwater impacted by volatile organic compounds, especially chlorinated solvents, gasoline and BTEX constituents, and other fuel oils, lubricants and heavier hydrocarbons as LNAPL including diesel, kerosene, jet fuel, solid grease and naphthalene • You have a high concentration contaminant source area in soil or groundwater, • You have low or heteroge
