Abstract

Cryptosporidium is a waterborne parasite which poses significant risks to drinking water safety. Despite its importance, considerable uncertainty remains regarding the effect of catchment characteristics and environmental conditions on the scale and timing of Cryptosporidium concentrations in rivers. This paper performs a spatio-temporal analysis of the environmental factors influencing Cryptospor…
