As the summer season ramps up, so does the possibility of Harmful Cyanobacteria Blooms (HCBs). Also known as blue-green algae, cyanobacteria are found in many bodies of water worldwide. They're normally harmless, but when their growth explodes and forms a bloom, they can release toxic chemicals into the water around them. They can cause symptoms in people ranging from skin irritation to liver damage, and they can be deadly to animals.
