RIVM has developed an interactive user-friendly computational tool, QMRAspot, to analyse and conduct Quantitative Microbial Risk Assessment (QMRA) for drinking water produced from surface water. In order to demonstrate production of safe drinking water, Dutch drinking water companies must conduct a QMRA every four years for the so-called index pathogens enterovirus, Campylobacter, Cryptosporidium and Giardia. The health based target is set at a risk of infection of less one per ten thousand person per year (95-percentile). QMRAspot enables the user to collect raw data in the proper format and to automate the process of QMRA.
Although developed for the Netherlands, QMRAspot can be applied by drinking water companies, researchers and policy makers worldwide.
