Water Fleas: Nature's Cleaners

Water fleas have helped researchers clean sewage water. Scientists have grown a population of water fleas from sediment found at the bottom of rivers. These organisms are capable of consuming many pollutants, such as leftover medications, pesticides, heavy metals, and chemicals. Water fleas can also adapt to various conditions and sustain their population on their own. Scientists believe that they can be successfully used in modern wastewater treatment plants.
