Groundwater vulnerability assessment: two case studies using GIS methodology

In the first case study presented here, a geographic information system (GIS) is used to create a groundwater vulnerability map of the Midlands and northwest of England by overlaying regional information on the solid geology, Quaternary drift cover and soil cover. The map reveals that areas of extreme and high groundwater vulnerability occur in the vicinities of Birmingham, Liverpool and Manchester. In the second study, a GIS is used to create a groundwater vulnerability map for southeast England and to combine this information with results from a routing model for the transport of hazardous aqueous waste within the region. -from Authors
