Site investigation activities at a commercial facility revealed TPH concentrations in groundwater above the applicable criteria of 5 mg/L. A single BIOX injection campaign was conducted in the sandy clay soils using direct push technology.
30 day post treatment analytical results showed significant reductions in TPH within the treatment area, and contaminant concentrations continued to decline. The site has subsequently been closed by the regulatory agency.
