Harmful cyanobacterial blooms (HCBs) are dense concentrations of cyanobacteria (photosynthetic single-celled microscopic organisms) that pose a health risk to people and animals. Cyanobacteria are commonly referred to as blue-green algae because they look very similar to algae. For this same reason, HCBs are commonly referred to as harmful algal blooms or HABs.
- Avoid contact with the water in the vicinity of the bloom, especially in areas where cyanobacteria are dense and form scrums.
- Do not ingest water from the bloom. Boiling, filtration, and/or other treatments will not remove toxins.
- Rinse fish with clean water and eat only the fillet portion.
- Avoid water spray from the bloom.
- Do not allow pets or livestock to drink water near the bloom, eat bloom material, or lick fur after contact.
- If people, pets, or livestock come into contact with a bloom, rinse off with clean water as soon as possible and contact a doctor or veterinarian.
- Report problems when you find them. This will ensure that the Department of Environmental Quality (DEQ) is aware of problem areas.
- Participate in the Wyoming Nutrient Work Group and help provide DEQ with input on how to most effectively address nutrient pollution.
- Be aware of potential contributions from your own home; use the recommended amount of fertilizer on your lawn, use phosphorus-free detergents, fix leaky septic systems and pick up pet waste.
