Precipitation and non-point source pollution

How to consider precipitation in EE, and If I add precipitation data on atmospheric model , how to add non-point source pollution load(includes planting and livestock)? As we know that non-point source pollutant always be brought by rainfall, If I gonna add non-point source I need to add flow data for it first, but the flow date of non-point source pollution is precipitation data, which have already be added on atmospheric model before. Do you have some cases which consider non-point source pollution in?
