Description

Regional Water Quality Monitoring and Evaluation for the Metropolitan-Phoenix Area Water Supply Regional Water Quality Monitoring and Evaluation for the Metropolitan-Phoenix Area Water Supply ASU has been working with regional water providers (SRP, CAP) and metropolitan Phoenix cities since 1998 on algae-related issues affecting drinking water supplies, treatment, and distribution. The results have improved the understanding of taste and odor (T&O) occurrence, control, and treatment, improved the understanding of dissolved organic and algae dynamics, and initiated a forum to discuss and address regional water quality issues. We propose continuing this program in 2009 and beyond. ASU would only continue this work if it benefits local WTPs. We believe that the program does so, by optimizing ongoing operations (i.e., reducing operating costs), improving the quality of municipal water for consumers, facilitating long-term water quality planning, and providing information on potentially future-regulated compounds. ASU has been monitoring water quality in terminal reservoirs (Lake Pleasant, Saguaro Lake, and Bartlett Lake) continuously from 1998 to the present for algaerelated constituents (taste and odors, and more recently cyanotoxins), nutrients, and disinfection byproduct precursors (i.e., total and dissolved organic carbon and organic nitrogen). Additional monitoring has been conducted in the SRP and CAP canal systems and in water treatment plants in Phoenix, Tempe and Peoria. During this work the Valley has been in a prolonged drought and recently one above average wet year, and this data provides important baseline data for development of new or expanded WTPs and management of existing WTPs in the future. The current work has improved the understanding of T&O sources and treatment, but additional research and monitoring into the future is necessary. ASU has leveraged financial support by local cities with significant funding from external agencies (primarily AwwaRF and USEPA). Many of the conceptual ideas initiated under this regional water quality framework lead to specific projects that conducted more in-depth research. These projects include, but are not limited to, the following:
