MODULE-3 Susceptibility and Vulnerability

Aquifer Susceptibility

Aquifer susceptibility is the ease with which a contaminant can reach the aquifer, determined by natural factors. An evaluation of an aquifer's hydrogeologic susceptibility is the first component when evaluating a water supply's vulnerability. Aquifer susceptibility is an evaluation of the physical potential for a source to be contaminated by the movement of chemicals from the land surface into a water supply. The method uses information on well age, construction, depth, past water quality history, and the extent of confining layers to provide an assessment of the source water's "physical susceptibility to contamination."
