Cyanobacteria, formerly referred to as blue-green algae, are found naturally in lakes, rivers, ponds and other surface waters. When certain conditions exist, such as in warm water containing an abundance of nutrients, they can rapidly form harmful algal blooms. Some harmful algal blooms are capable of producing toxins, called cyanotoxins, which can pose health risks to humans and animals through drinking water and recreational water exposure. Additionally, harmful algal blooms can create taste and odor problems in drinking water, which do not have adverse human health impacts but can create an earthy and musty taste and smell.
Health Effects of Algae and Cyanotoxins
Cyanotoxins released by some cyanobacteria can cause allergic reactions, stomach cramps, nausea, headaches, fever, sore throat, muscle and joint pain, oral blisters and liver damage. Long term exposure can lead to more serious health conerns, according to the EPA: "Continuous sublethal or low-level exposures to cyanotoxins can potentially lead to the development of gastrointestinal, neurological, and liver disorders."
