Assessing Water Quality Monitoring Needs, Tools, Gaps, and Opportunities for Potable Water Reuse


With the occurrence of climate change, more stringent nutrient controls for wastewater discharges, and population growth, water reuse is more important than ever before. Although potable reuse has grown considerably in recent years, some consumers are still reluctant to support it. Utilities and regulators face challenges in proving that recycled water is safe and in understanding the appropriate use of sensors to monitor plant operations and water quality. These needs encompass four distinct, but related areas: microbial contaminants, chemical contaminants, operational needs, and technology/data management and interpretation.

This webcast presented the results of project, Assessing Water Quality Monitoring Needs, Tools, Gaps, and Opportunities for Potable Water Reuse (5079), including a database of technologies that are conventionally available or promising for the future, needs that future technologies can address, ways to select the appropriate water quality and treatment monitoring tools, and tips for optimizing the information the tools provide to ensure the quality of recycled water.
