Optimizing Filter Operation in an Ozone-Biofiltration Plant to Reduce Selection for Opportunistic Pathogens in Drinking Water Production

Project Update

Reporting Period: March 2, 2019 – September 1, 2019. During this reporting period, several activities to achieve Objectives 1 and 3 have been carried out, including extensive sampling of pilot-scale biologically active carbon (BAC) filters under acclimation and experimental conditions, DNA extractions of the samples collected, and qPCR quantification of total bacteria and nontuberculous mycobacteria in water and media.
