A decision support system for emergency response to groundwater resource pollution in an urban area (Ljubljana, Slovenia)
2015
Groundwater is an important resource for drinking water. Although it is a relatively stable and protected water resource, its quality, especially in highly urbanized catchments, is vulnerable to pollution related to unusual events or accidents causing releases of hazardous substances. To ensure the safe supply of drinking water in these cases, prompt actions must be taken and solutions must be delivered under time constraints. This paper describes a decision support system for emergency groundwater management that was developed to improve activities after the discovery of pollution in the catchments of drinking water abstraction wells in the Ljubljansko polje aquifer. It is a system based on a monitoring network and the integration of numerical modeling techniques with expert knowledge. The integration of logically interlinked activities, including the detection of pollution in the groundwater, the simulation of pollution propagation and decision making, into a common system provides a basis for proactive water resource management. The user-friendly interface enables water managers to utilize modeling tools and rapidly access information for mitigating pollution of groundwater resource, which in the presented case significantly contributes to a safer drinking water supply.
