Full-Scale Treatment Programs

Full-scale treatment programs usually follow bench scale and/or pilot treatment programs and consist of two treatment phases: a primary phase and a polishing phase.

Full-scale applications range in size and duration dependent upon the contaminant mass, the amount of oxidant to be injected, and the time associated with its delivery. The design of each full-scale treatment is adapted in order to achieve the site-specific goals of our clients.

The primary phase of treatment is designed to effectively reduce contaminant concentrations across a site. The primary phase of treatment typically achieves 90% reductions from baseline conditions (source removal is typical). GCI also includes the design of a polishing treatment in its costing in the event that impacts in some areas on site were not reduced enough to meet treatment goals.

Polishing treatments follow the primary phase of treatment and focus on treating specific hot spot areas that were not fully remediated during the primary phase. A polishing treatment is about 10% of the size of the primary treatment.
