Estimated uncertainty in the form of standard deviations and classification of uncertainty in three levels are presented in the result report for selected topics concerning:
1) storm water concentrations from different land use and 2) treatment effects for the individual selected facility, see also the guide Uncertainty.

This is the beginning of a more complete quantification tool that will be complemented by calculated uncertainties for total estimated pollutant concentration and total
estimated pollutant load from the subwatershed area etc.
