DWQ’s POWR Program (Protecting Outdoor Water Recreation with Environmental Data) monitors and tests Utah’s waters for harmful algal blooms (HABs) and waterborne pathogens.
Can I Eat Fish from Waters Experiencing a Harmful Algal Bloom (HAB)? Toxins can accumulate in fish in waters experiencing a HAB. The highest concentrations are in the organs, particularly the liver, and fat deposits. Muscle tissue typically has lower toxin levels. Fish taken from waters with intermittent blooms are unlikely to have toxin levels…

Toxins from harmful algal blooms (HABs), called cyanotoxins, can enter drinking water supplies from surface water sources or ground water sources impacted by surface water. An increase in the incidence of HABs around the country has prompted the Environmental Protection Agency (EPA) to issue guidelines and recommendations for cyanotoxin values in drinking water and recommendations…
