In November 2023, NHDES released a statewide strategy to prevent the increase of, and eventually control, cyanobacteria blooms in New Hampshire’s surface waters. The plan was required by the state legislature and included input from a 17-person cyanobacteria advisory committee.
Included in the plan are several key strategies and goals necessary to curb cyanobacteria blooms occurrences and risks, such as:
Implementation and support for policies and practices that reduce nutrient inputs to reduce bloom occurrences.
Enhanced lake management programs to diagnose blooms and support corrective actions that minimize their occurrence.
Increase public awareness for people who recreate in our water bodies to recognize cyanobacteria blooms and respond accordingly to minimize health risks.
Increase cyanobacteria bloom monitoring capacity to inform the public when and where blooms are occurring.
Prevent, detect and respond to cyanobacteria blooms in surface waters that serve as public drinking water supplies to minimize health risks to customers.
