Because our patented injection equipment and methodology are equipped to deliver all types of oxidants and substrates to the subsurface, GCI evaluates each site to determine which oxidant provides the best fit, both chemically and economically.

GCI initially researches the ability of each oxidant to destroy the type of contamination present. For example, at sites containing BTEX compounds, it is well known that permanganate cannot oxidize the benzene ring, thus eliminating permanganate as an oxidant choice at sites containing BTEX impacts. Next, GCI calculates the number of pounds of contaminant present at the site and corresponding number of pounds of oxidant necessary to destroy that amount of contamination.

Using the calculated total amount of oxidant to be delivered, GCI then determines the rate of delivery of the oxidant solution by evaluating the lithology. Finally, GCI looks at the cost of the oxidant and the timeframe associated with delivery. The oxidant package that is more effective and less expensive than the other is then selected.
