“…The WMP/WSP approaches require identifying hazardous conditions, enacting controls where required, monitoring the controls, and monitoring Legionella to confirm that the controls are adequate. This same approach can be applied for L. pneumophila management by drinking water utilities/suppliers (Burlingame & Bartrand, 2023).…”

A protocol for responding to Legionella pneumophila detections in distribution system samples is presented and justified. The protocol was developed using existing protocols for building water systems, vetted in workshops, and provided to utilities participating in a research project. The protocol provides action levels and actions that utilities can take when L. pneumophila is detected in distribution system samples. Action levels are based on the best available science and expert judgment and are similar to those in protocols for assessing building water system monitoring results. Action levels should be reassessed as additional data and knowledge on the occurrence and growth potential of L. pneumophila in distribution systems become available. All positive detections trigger assessments that focus first on conditions local to the sample location and then extend further into the distribution system. Higher concentration or more frequent detections initiate more assertive responses and communication than lower concentration and frequency detections. The protocol provides a starting point for the development of protocols for purposes such as L. pneumophila operational surveillance or within an outbreak investigation.

“…A water safety plan (WSP) is a best management practice that complements SMCL regulations. The WSP approach integrates centralized and distributed points of control that are tailored to monitor a specific water utility and address its risk management plans (Burlingame & Bartrand 2023, WHO 2023. WSPs can include monitoring and response to customer complaints and premise plumbing issues.…”

Key TakeawaysAesthetic water quality is an important but sometimes inadequately addressed aspect of providing a safe and reliable drinking water supply.In the United States, federal regulations provide a starting point for maintaining aesthetic water quality; however, this framework falls short of providing the tools needed to effectively implement the standards.A water safety planning approach can complement regulatory frameworks or be used as an industry standard for better management of aesthetic water quality.

The World Health Organization considers water quality aesthetic parameters affecting taste, odor, and appearance, as factors to be monitored to determine the overall safety of water. Water safety plans (WSPs) can be used by utilities to proactively identify aesthetic hazards, rank them by likelihood of occurrence and consequence to the utility, generate risk scores, and provide direction on how to monitor, mitigate, and verify that controls are in place. The City of Wichita Falls Public Water System (CWF PWS) used the water safety planning approach to outline how aesthetics may negatively affect the system from source water, in-plant processes, and into the distribution system. By proactively identifying these hazards and outlining what to do using a WSP, the utility has put measures in place to ensure that aesthetically acceptable water is delivered to their customers. This article outlines the water safety planning process for water quality aesthetics and how the CWF PWS developed and implemented its WSP.
