Drinking Water System Effective Management
Effective management strategies for blooms in the system depends on the characteristics of the bloom. Treatment processes can include oxidation, coagulation, activated carbon, etc. For more information on cyanotoxin treatment processes and their effectiveness, refer to EPA’s website.

Source Water Control Measurements
Control measures for blooms in source water can include measures such as aeration, algaecides, coagulation, and more. A complete list of measures for source water can be found on the EPA’s website
