Remediation

Stabilization. Solidification. Chemical Fixation. Chemical Oxidation.

The following treatment technologies typically offer significant savings when compared to off-site treatment and disposal. They offer economical treatment methodologies for treating heavy metals, solid organics, PCBs, and other waste streams.

Stabilization
Stabilization techniques limit the solubility or mobility of contaminants. To accomplish this, reagents or other specialized materials are blended with the soil and/or sludge. Stabilization ensures that the hazardous constituents are suspended in their least mobile or toxic form.

Solidification
Solidification results in a solid, low-permeable block of contaminated soil. To accomplish this, reagents are utilized to mechanically lock the contaminants within the solidified matrix. This process significantly decreases contaminant migration.

Chemical Fixation
This technology achieves the destruction of contaminants and creates non-hazardous materials. Similar to stabilization and solidification, chemical fixation requires the blending of reagents with the contaminated material. The reagents used during the mixing/blending process effect destruction or chemical bonding of the contaminant(s).

Chemical Oxidation
In-situ chemical oxidation (ISCO) is a cost-effective and viable remediation technology for the treatment of petroleum-based contaminants and VOCs in soils, sediments, and groundwater. Once a representative sample has been analyzed and the chemicals of concern are identified, bench testing is performed in order to determine the type and quantity of reagent to employ.
