Algae and Cyanobacteria: Options for Monitoring and Treatment”
Due to climatic changes such as increasing temperatures, longer periods of drought, and longer and harder precipitation events, algae and cyanobacteria (so-called blue-green algae), proliferate in many lakes across the world. While this has been happening for some time, attention to this issue reached public consciousness in the summer of 2014, when a large cyanobacterial bloom in Lake Erie led to the complete shutdown of Toledo, Ohio’s water supply for several days, due to high levels of microcystins (a group of cyanotoxins) in the finished water. Since that time, several other cyanobacterial blooms leading to shutdowns have occurred, most recently during the summer of 2018 in Salem, Oregon and Lake Okeechobee, Florida.
In Dr. Schneider's presention, hewill discuss several available monitoring methods for evaluating cyanobacteria in freshwater bodies, several methods for treating water sources to prevent algal and cyanobacterial proliferation in the source waters, and methods to treat for algal toxins within the treatment plant. Case studies for ultrasonic treatment of a lake and a decision support tool for treatment plants will be highlighted.
