A major limitation of QMRA is constituted by a
The norovirus concentrations in the source water during various upstream loading conditions were quantified using hydrodynamic modelling. Based on the modelling results, the required GS967 of norovirus concentrations at the DWTP was calculated and compared with the estimated performance of the DWTP. To our knowledge, this article is the first to employ discharge-based QMRA, combined with hydrodynamic modelling, in the context of drinking water management.
