FEATURE ARTICLESEmerging compounds: A concern for water and wastewater utilitiesLorien J. Fono and H. Stephen McDonald Although more research needs to be conducted regarding the effects of compounds of emerging concern, it is likely that these compounds represent the next realm of regulatory oversight. Examining mergers in small CWSs: The role of regulatory compliance Min-Yang A. Lee and John B. Braden Despite extensive research and policy initiatives to improve the technical, financial, and managerial capacity of small drinking water systems, little research has focused on understanding how mergers can build capacity within the drinking water industry. Occurrence of perchlorate in sodium hypochlorite Peter Greiner, Clif McLellan, Dale Bennett, and Angie Ewing Responding to the detection of perchlorate in sodium hypochlorite by the Massachusetts Department of Environmental Protection, NSF International surveyed for the contaminant in drinking water treatment chemicals from production facilities across the United States and Canada. Effects of changing disinfectants on lead and copper release Glen R. Boyd, Kylee M. Dewis, Gregory V. Korshin, Steven H. Reiber, Michael R. Schock, Anne M. Sandvig, and Richard Giani More utilities are using chloramines in place of free chlorine, but new information has contributed to a greater understanding of factors influencing increased corrosion and metals release. Optimizing PAC and chlorination practices for cylindrospermopsin removal Lionel Ho, Najwa Slyman, Uwe Kaeding, and Gayle Newcombe Results from this study indicate that the combination of powdered activated carbon and chlorination can provide a multibarrier treatment approach for the mitigation of cylindrospermopsin, provided both options are optimized. Sensor network design of contamination warning systems: A decision framework Regan Murray, Robert Janke, William E. Hart, Jonathan W. Berry, Tom Taxon, and James Uber Because a contamination warning system is not just a straightforward application of a software tool, the authors present a decision framework that uses the Threat Ensemble Vulnerability Assessment and Sensor Placement Optmization Tool to determine optimum sensor placement. Committee Report: Disinfection Survey, Part 2—Alternatives, experiences, and future plans AWWA Disinfection Systems Committee In part 2 of its report, the AWWA Disinfection Systems Committee describes selection rationales and operational details of respondents to the survey.
