Cryptosporidium can transport from the soil to the water resulting in the contamination of the surrounding water bodies. However, there are few pieces of research on the transport of Cryptosporidium from the slope soil to the surrounding water. The experiment simulated the transport of Cryptosporidium surrogate, carboxylate YG polystyrene, influenced by the rainfall intensity, rainfall pattern, soil type, and land slope, from the soil to water, to understand the transport of Cryptosporidium surrogate under these different conditions. The results showed that the transport of Cryptosporidium surrogate was affected by the surface runoff factors, that is, the high rainfall intensity, high rainfall frequency, steep slope and high sand content soil that resulted in the high transport of the Cryptosporidium surrogate.
