Harmful algal blooms (HABs) naturally occurring cyanobacteria that develops in the water that can produce potent cyanotoxins that pose serious health risks to humans, pets, and livestock. Waterborne pathogens such as bacteria, viruses, and parasites in the water can cause a lot of human and wildlife illnesses. Utah's Division of Water Quality works in conjunction with local health departments to alert the public about these waterborne pathogens and blooms. When budget allows, they also perform daily testing of popular recreational water bodies to ensure civilian safety. These handouts were created as a resource for the public when visiting water bodies in Utah. They provide information on the pathogens and cyanobacteria as well as ways they can stay safe while recereating in the water.
