The report provides the in-depth data analysis from the SITE Program's six-week demonstration of BioTrol's Aqueous Treatment System (BATS) at the MacGillis and Gibbs Company wood treatment facility in New Brighton, Minnesota. The pilot scale (5gpm), fixed-film biological system using a pentachlorophenol-specific bacterium was evaluated at three groundwater throughput rates. Operational and analytical data were carefully monitored throughout to establish a database to use in evaluating the vendor's claims for pentachlorophenol (PCP) and polynuclear aromatic hydrocarbon (PAH) removal. It was concluded that the system achieves over 95% PCP removal (vendor's claim: 90%), probably by mineralization to carbon dioxide water and chloride ion. Because of unexpectedly low concentrations in the groundwater, removal of PAH's could not be determined.
