ISCO SOIL AND GROUND WATER DECONTAMINATION PROTOCOLS

ISCO process is a  patented remediation technology to effectively degrade impacted/contaminated soils and groundwater at contaminated sites. This technology, developed by Reardon Environmental, Inc, and improved by use of the cost effective and safe CELLC AO Solution Generation, is an innovative delivery system capable of injecting liquid inoculants into soils. It is a high pressure, low volume injection system. Liquid inoculants are injected at pressures up to 5,000 psi. By injecting low volumes of liquid inoculants at high pressure, micro-fractures are created in soils with low permeability. Once the micro-fractures are opened, the inoculants are effectively dispersed into the soil and/ or water column.  

Where the soil above the water table is contaminated, the ISCO process is the only chemical oxidation method whereby the soil can be remediated in situ. Although other methods have been employed to treat the water table, the process avoids costly ‘dig and haul’ of soil required to prevent recontamination of the groundwater from overlying, contaminated soil. The delivery system uses high pressure fracturing and dispersion to mix the treating chemicals and the pollutants rather than relying upon the hydrology of the water table. It ensures complete and rapid treatment of the contaminants. Injection chemicals are targeted at the specific locations of the pollutants, minimizing chemical usage while treating only the region of contamination, not the entire water table below the site.  

The process can remediate dense phase non-aqueous liquids (DNAPLs) where few, if any, other methods are effective. Methods utilizing low pressure injection of high volumes of treating chemicals into the water table are generally not capable of meeting EPA standards for groundwater, due to the inability of adequately mixing with the non-aqueous phase pollutant. The Reardon process provides the intimate contact between the treating chemicals and pollutants to achieve contaminant reduction.
