Title: A simple model for quantifying Cryptosporidium transport, dilution and potential risk in reservoirs

Authored by: Antenucci, J.P., Brookes, J.D. and Hipsey, M.R.

Abstract:

A simple model is presented to assist in quantifying the concentration and viability of Cryptosporidium contamination in lakes and reservoirs after riverine inflow events. The model includes the basic dynamics of inflows, along with fate transformations associated with temperature, ultra-violet (UV) light exposure and sedimentation, and can be accessed online. The model is applied to inflow events in three reservoirs to demonstrate the ability to simply quantify pathogen concentration. As well as assisting with risk assessment, the model can also be used to improve sampling strategies after inflow events.
