N1 - Funding Information:
The pilot study was primarily funded and operated by the City of Reno Public Works Department . A portion of the study was also funded by WateReuse Research Foundation projects WRF-08-05 ( Use of ozone in water reclamation for contaminant oxidation ) and WRF-09-10 ( Use of UV and fluorescence spectra as surrogate measures for contaminant oxidation and disinfection in the ozone/H 2 O 2 advanced oxidation process ). The comments and views detailed herein may not necessarily reflect the views of the City of Reno or the WateReuse Research Foundation. This study would not have been possible without the assistance of Stantec (formerly ECO:LOGIC Engineering; Vijay Sundaram and Robert Emerick), the Reno-Stead Water Reclamation Facility (Stan Shumaker, Michael Drinkwater, and Scott Nelson), EAWAG (Yunho Lee and Urs von Gunten), WesTech Engineering, Inc., and APTwater, Inc. Finally, the authors would like to thank researchers and staff at the Applied Research and Development Center at the Southern Nevada Water Authority (Brett Vanderford, Susanna Blunt, Josephine Chu, Shannon Ferguson, Jasmine Koster, and Christy Meza) for all of their efforts during this project.

N2 - In an effort to validate the use of ozone for contaminant oxidation and disinfection in water reclamation, extensive pilot testing was performed with ozone/H2O2 and biological activated carbon (BAC) at the Reno-Stead Water Reclamation Facility in Reno, Nevada. Three sets of samples were collected over a five-month period of continuous operation, and these samples were analyzed for a suite of trace organic contaminants (TOrCs), total estrogenicity, and several microbial surrogates, including the bacteriophage MS2, total and fecal coliforms, and Bacillus spores. Based on the high degree of microbial inactivation and contaminant destruction, this treatment train appears to be a viable alternative to the standard indirect potable reuse (IPR) configuration (i.e., membrane filtration, reverse osmosis, UV/H2O2, and aquifer injection), particularly for inland applications where brine disposal is an issue. Several issues, including regrowth of coliform bacteria in the BAC process, must be addressed prior to full-scale implementation.
