Blue-Green Algae Bloom
Blue-green algae are a type of bacteria. They occur naturally, but if their numbers get too high they can pose health risks to humans and animals.
Blue-green algae blooms form when algae, which are normally found in the water, start to grow very quickly. Blooms can form in warm, slow-moving waters that are rich in nutrients from sources such as fertilizer runoff or septic tank overflows. Blue-green algae blooms need nutrients to survive.
