Federal, state and local agencies monitor lakes and reservoirs that have high recreational use, and provide our program with laboratory results of water samples collected when a cyanobacteria (blue-green algae) bloom is suspected. These lab results are the basis for issuing recreational use health advisories. We consistently work with:
U.S. Centers for Disease Control and Prevention works on a national level to educate and promote clean water for healthy swimming in recreational waters and to investigate the impact of harmful algae blooms on human health. The CDC also tracks illnesses from exposure to harmful algae blooms.
Washington Department of Health has a harmful algae bloom surveillance program and does toxin testing of algae blooms in Washington freshwaters.
