Feasibility Study for Early Warning Systems for Algae-Induced Tastes and Odors Feasibility Study for Early Warning Systems for Algae-Induced Tastes and Odors The reservoirs in central Arizona are a major water supply system for the Phoenix metropolitan area. These reservoirs are fed by a combination of the Salt River water shed, the Verde River water shed, and Central Arizona Project water transported by a canal system from the Colorado River. In addition to water storage and hydropower, the lakes also have a great recreational value, including boating and fishing. But fish mortality has been a recurrent problem in the Salt River Lakes and blooms of algae known to release toxins, such as the chrysophyte Prymnesium parvum (Golden Alga), as well as cyanobacteria (e.g., Cylindrospermopsis) are found at high abundances in the AZ reservoirs (Fig. 1). These nuisance algal species are also known to be responsible for taste and odor issues, which can significantly impact customer satisfaction and reduce customer confidence in the quality of the water supply. Additionally, algal biomass makes a significant contribution to the particle loading of the water column, increasing the total suspended solids (TSS = total organic matter + sediments) that prove problematic for city water treatment plants. Therefore the ability to remotely monitor the reservoirs for the presence of algal blooms, in particular of those species known to be responsible for taste and odor problems, has the potential for providing advance warning of both environmental and water processing issues.
