Cryptosporidium
"Cryptosporidium is a microscopic parasite that causes the diarrheal disease cryptosporidiosis. There are many species of Cryptosporidium that infect animals...its protective outer shell allows it to survive outside the body for long periods of time, and also makes it very tolerant to chlorine disinfection. While this parasite can be spread in several different ways, water (drinking water and recreational water) is the most common way to spread the parasite. Cryptosporidium is a leading cause of waterborne disease among humans in the United States." CDC.
