"Crisis to Success: Lessons for Utilities from the Tucson Water Turnaround"
Michael J. McGuire, MJM, Inc; Marie S. Pearthree, Central Arizona Project (retired)
A debacle of corrosive water destroying pipes preceded the events in Flint, Michigan by over two decades. In November 1992, the water department for Tucson, Arizona, (Tucson Water or TW) began delivery of a new water supply: treated surface water from the Central Arizona Project (CAP) primarily Colorado River water. Putting treated CAP water into the TW distribution system caused a devastating corrosion problem that resulted in colored water (e.g., red, orange, yellow and brown) flowing from customer taps. The purpose of this presentation is to summarize the results of an exhaustive investigation into the debacle and to chronicle how TW changed its management practices, dramatically improved its abysmal credibility, ended over pumping of its groundwater and created a sustainable water supply for the TW service area. The mistakes that Tucson Water and other utilities have made when changing water supplies and water quality, and the successful steps that Tucson Water took to regain credibility and public trust, provide lessons for all water utilities when contemplating similar actions. The "lessons learned" presented from this investigative study cover many aspects of utility management including technical research, organizational culture and structure, open and effective management, financial prioritization, and public outreach and engagement.
"Newark #nofilter: Point-of-Use Filter Study"
Matthew Young, CDM Smith; Tosin Adetutu, City of Newark
After the City of Newark exceeded the Lead Action Level (LAL) set by the Lead and Copper Rule (LCR) in 2017, a corrosion control study was performed to determine why the system was not meeting regulations and the best course of action to fix the issue. Based on sequential sampling and lead scale analysis performed on lead service lines in Newark's Pequannock system, it was determined that Newark had tetravalent lead scales that were in the process of breaking down. To protect residents from the high lead levels caused by the unstable scales, Newark initiated a program to distribute 40,000 NSF-certified point-of-use (POU) filters and replacement cartridges as a temporary measure to protect residents while the permanent solutions, a new zinc orthophosphate chemical feed system and a lead service line replacement program, were implemented. The topics discussed will include sampling protocol and coordination across multiple agencies and stakeholders. Public outreach methodology and scheduling logistics will also be included. The tools and process used to quickly deploy a mobile sampling application will be shown. The variety of criteria (filter usage, installation, and maintenance) that disqualified data will be discussed. Most importantly, the final results of the study will be analyzed.
