This volume presents contemporary issues surrounding groundwater pollution risk assessment and the application of vulnerability and risk assessment maps for the effective protection and management of aquifers. It describes numerous new and improved approaches to intrinsic and specific vulnerability assessment (modified DRASTIC, GOD, VULK, VURAAS), some coupled with geophysical and hydrological surveys and hydrodynamic and transport modelling. Widespread use is made of GIS format. Topics include aquifer pollution vulnerability,
Modeling and mapping groundwater protection priorities using GIS, and the application of a groundwater contamination index to assessment of confined aquifer vulnerability.
