PATHOGEN FATE AND TRANSPORT IN SURFACE WATER FLOW

摘要

This project was designed to advance the state of knowledge regarding sources, fate and transport of pathogens such as Cryptosporidium, enteric viruses and bacteria in drinking water catchments. Its principal goal was to facilitate the development of predictive models to describe expected concentrations of waterborne pathogens at critical downstream locations. Major findings were the water quality benefits of improved riparian buffer management, particularly the vegetative cover, which could be used to provide design criteria for setback distances to waterways. One encouraging finding was that the setback design criteria described elsewhere for phosphorus and sediment entrapment appear to be reasonable for Cryptosporidium entrapment.
