Oxidant Choice

The following oxidants and treatments are currently utilized by GCI.  In addition, Geo-Cleanse is developing procedures to use sodium persulfate for ISCO treatment programs.

Fenton's Reagent
Fenton's reagent chemistry, a powerful and non-selective reaction, has the ability to oxidize a wide variety of organic contaminants into non-regulated compounds (CO₂ and H₂O). It is the most effective and economical remediation method for sites with high contaminant concentrations, including NAPL.

Permanganate
GCI has developed an injection technology to utilize potassium or sodium permanganate for chemical oxidation. Permanganates are best used for treating large sites with low-level dissolved chlorinated concentrations. The reaction between permanganate and the contaminant is not adversely effected in carbonate-rich environments.

Heavy Metals Treatment
This patent pending Geo-Cleanse treatment process delivers a specially formulated treatment solution to environments with heavy metal contamination. This solution creates an electron transfer reaction, precipitating and reducing the heavy metal contaminants from groundwater.

Bio-Enhancement  
When introduced into contaminated environments, biological enhancements provide an effective means to remediate groundwater. These custom designed systems include delivery of macronutrients and either hydrogen producing reagents (i.e., lactates, molasses, and vegetable oils), or oxygen producing reagents to stimulate natural microbial degradation of organic and inorganic contaminants.

Surfactant Injection
Injection of a surfactant is typically used to help desorb contaminants from soils prior to a treatment program.  Surfactants help to remove strongly sorbed compounds into the groundwater where they are more easily remediated.
