Cryptosporidiosis is a severe gastrointestinal disease caused by the transmissive form of Cryptosporidium parvum protozoan—its oocysts. Cryptosporidium oocysts are ubiquitous in untreated water and extremely resistant to harsh environmental conditions, including standard water treatment procedures. This project provides crucial knowledge on the risk of human exposure to Cryptosporidium; specifically it provides information on how both land use and environmental factors in a watershed affect the transport of oocysts before they reach a water supply system. It also provides a tool for quantitative evaluation of the risk of Cryptosporidium contamination associated with environmental factors and agricultural and other land-use practices.
