DBP Impacts From Increased Chlorine Residual Requirements
Damon K. Roth and David A. Cornwell
Utilities are required to maintain a chlorine residual throughout their distribution system, but the minimum level is defined only as “detectable.” Establishing numeric minimums for analytical methods used for disinfectant analysis would help utilities assess whether they are successfully maintaining disinfectant residuals. The goal of this study was to determine how changing the current disinfectant residual requirement to a numeric minimum value would affect public water systems, particularly those that maintain very low detectable disinfectant residuals in their distribution system.

A Costly Endeavor: Addressing Algae Problems in a Water Supply
Catherine R. Dunlap, Karen Seligman Sklenar, and Laura J. Blake
Algal blooms in drinking water supplies can result in unpalatable flavors in tap water, human health concerns, and increased treatment costs. This study estimated the costs associated with treating algae and algal by-products in the Waco, Tex., drinking water supply during 2002–2012. This analysis is intended to help water utility managers understand the costs associated with dealing with elevated nutrient loading and algal blooms in drinking water supplies.

Sustaining Aging Systems
Kenneth L. Mercer
To ensure sustainability into the future, utilities must address the constant need for maintenance and repair while planning for cyclical renewal and replacement of system components or sections. There are financial benefits of planning ahead and conducting regular maintenance as opposed to waiting until some sort of incident creates urgency. Before things break down, much can be done to extend the life of water system components. Proactive maintenance can extend asset life, and periodic inspections and condition assessments can detect problems before they balloon into crisis. Targeted levels of service are better supported by regular, informed maintenance that avoids or reduces reactive repairs.
