If you ever have noticed a waterbody wigreen water on the edge of a laketh a layer of green scum coating its surface or a slick green film resembling a paint spill, you likely have witnessed a cyanobacteria bloom. Cyanobacteria, sometimes referred to as blue-green algae, are tiny organisms found naturally in aquatic ecosystems and numerous other environments. Typically, these organisms are harmless and go unnoticed; however, under certain conditions, cyanobacteria can form a dense mat or bloom on the surface of the water that may produce harmful toxins. These blooms and associated toxins pose a significant threat to humans, animals, and the ecosystem. They can cause illnesses, skin irritations, or worse and can threaten drinking water supplies and recreational opportunities. As cyanobacteria bloom incidence continues to increase, EPA strives to create and improve methods for bloom prediction, monitoring, and management.
The Northeast Cyanobacteria Monitoring Program, covering the states of Rhode Island, Connecticut, Massachusetts, Vermont, New Hampshire, and Maine, will help generate region-wide data on bloom frequencies, cyanobacteria concentrations, and spatial distribution through three coordinated projects: bloomWatch, cyanoScope, and Cyanomonitoring. Each project relies on the general public, citizen scientists, and trained water professionals to locate potential blooms and report applicable information, so we can improve cyanobacteria monitoring and learn more about harmful blooms in the Northeast.
