Because the presence of the building prevented the majority of the contamination from being removed, Cedar Creek installed a network of wells for injection of chemical reagents. These twenty 18-foot wells were installed in two days, and injection proceeded in a round-robin fashion for five days.
The week-long treatment produced a 96% reduction in gasoline hydrocarbons in groundwater at a fraction of the cost of conventional, long-term, in-situ technologies.
In Mossyrock, Washington, leaking underground storage tanks below a large building contaminated soil that could not be easily removed. Cedar Creek installed injector heads for injection of chemical reagents. After one week, the site saw a 96% decrease in gasoline hydrocarbons in groundwater. This solution was fast, efficient, economical, and safe.
