The goal of this project was to analyse the risk to groundwater from microbiological contaminants in sewage leaking from sewers. A probabilistic risk model was developed as a sub-tool of the existing Borehole Optimisation System (BOS). Nottingham was used as a case study for validation of the model and to explore the consequences of the results. In recent years, urban groundwater in the UK has been recognised as a potentially valuable resource because of the environmental problems associated with the rising urban water tables and heavy reliance upon rural aquifers. To achieve more sustainable use of our groundwater resource, a balance needs to be attained whereby pressures on rural groundwater are reduced and the continuing rise in urban groundwater levels is arrested. This in turn requires tools to be developed that can be used as aids in decision-making on matters pertaining to urban groundwater pollution risks.
