- Weathered Wood Treating Waste Effectively Washed
- Carcinogenic Polycyclic Aromatic Hydrocarbons Remediated +99%
- Pentachlorophenol Reduced +98%
BioGenesis™ soil washing technology was used to perform treatability testing on a former wood treating facility site contaminated with carcinogenic PAHs, pentachlorophenol, creosote, arsenic, and petroleum waste from vehicle maintenance and fueling. The levels of contamination were 11,000 to 15,000 ppm TPH as diesel, 300 to 800 ppm TPH as gasoline, 700 to 1,400 ppm polycyclic aromatic hydrocarbons, 130 to 310 ppm pentachlorophenol, 2.5 to 5.5 ppm dioxin/furan, and 350 to 600 ppm arsenic. Removal effectiveness was >99% TPH, >98% PCP, >99% PAH, >97% dioxin/furan and >80% arsenic.

BioGenesis was retained by a major regional engineering firm to perform soil washing treatability studies of a former wood preserving site. The purpose of the study was to assess the applicability of BioGenesis technology to achieving the established project cleanup goals, to provide sufficient information to develop cost estimates, and to provide data necessary to scope and implement field activity.
Removal rates for TPH, PAH, PCP, and dioxin/furan were highly successful. Both the unsaturated and saturated soils were very well suited to cleanup using BioGenesis™ large particle washing technology.
