This document is an evaluation of the BioTrol, Inc., Aqueous Treatment System (BATS), a fixed-film, aerobic biological treatment process for contaminated groundwaters and other wastewaters.This report summarizes and analyzes the results of the Superfund Innovative Technology Evaluation (SITE) Program's six week demonstration at the MacGillis and Gibbs Company wood preserving site in New Brighton, MN. Other pertinent data from BioTrol investigations are included to support the demonstration results. Conclusions were reached concerning the technological effectiveness and economics of the process and its suitability for use at other sites. During the SITE demonstration, operations and sampling and analysis were carefully monitored to establish a database against which the vendor's claims for the technology could be evaluated reliably. These claims were that the BATS could achieve 90% removal of pentachlorophenol (PCP) and polynuclear aromatic hydrocarbons (PAHs) and that penta removal was by mineralization. The conclusions from the pilot scale demonstration study and other available data are:
