A pathogenic protozoan called Cryptosporidium has the ability to resist chemicals like chlorine that are often used to sanitize public drinking water. This protozoan is introduced to water supplies through contact with animal or human waste. Suggest one way to limit Cryptosporidium in water supplies to provide people around the world with fresh drinking

water.

One way to limit Cryptosporidium in water supplies is to install effective filtration systems that can remove the protozoan from the water. This can be achieved through the use of advanced filtration technologies like microfiltration, ultrafiltration, or reverse osmosis. These systems can remove even the smallest Cryptosporidium protozoans, ensuring that the drinking water is safe and clean. Additionally, improving sanitation practices and proper handling of animal and human waste can also be effective in limiting the presence of Cryptosporidium in water supplies.
