GAEPD: Chemical Remediation for UST Cleanup

Recently we have seen more acceptance from the Georgia Environmental Protection Division when it comes to chemical remediation to remove free product at leaking underground storage tank facilities. There has been mixed feelings about what conditions are right for using chemical remediation and differences begin with the contractors performing the remediation. For example, some contractors indicate chemical remediation can only be effective when free product is less than 0.5 foot thick at a site, while some others indicate that as long as a mobile multi-phase extraction/high vacuum extraction event is performed prior to the injection, injection of chemicals can be very effective with thicknesses as high as 1 foot. What are your thoughts on this?
