GCI considers permanent injection wells crucial during a Fenton's reagent injection for the following reasons:

•This enables targeted oxidant injection to only those locations where remediation is necessary. This also ensures that the remediation is complete by monitoring and collecting field data to document the program goals are complete prior to post remedial sampling and analysis.
•Ability to monitor groundwater at adjacent locations to determine if the appropriate conditions have been established and that oxidant has permeated throughout the entire site.
•Inexpensive installation. Injection wells are installed using direct-push drilling technologies and either CPVC or schedule 80 Black iron pipe.
•Ability to deliver a large volume of oxidant across the site. As the oxidant moves away from the injection wells, injected concentration decrease as the oxidant solution is dissolved in groundwater. Thus in order for GCI to deliver a calculated charge of oxidant great distances away from the injection locations, large quantities of oxidant must be applied.
• Ability to establish a larger radius of influence. Temporary injection locations, due to the nature of that type of delivery, can only distribute reagents a couple of feet out from each location. Using permanent injectors, in conjunction with our patented equipment, GCI can establish a larger radius.
•Reinjection purposes. Injectors can remain in the ground post-treatment and can be used as monitoring points or as injection locations for additional oxidants or biological enhancing materials in the future.
