€ The Drastic methodology also helps users to recommend the most hydrogeologically acceptable setting for 
municipal and waste disposal sites, and also helps users to direct resources for further evaluation. 
€ When the state or local administrator have limited resources available to devote to ground water protection, they 
are forced to focus these resources in certain areas. The pollution potential map helps identify areas, which are 
more or less vulnerable than others to contamination. This delineation allows administrators to direct their 
resources to those vulnerable areas most critical to ground water contamination, thereby making use of most of 
the limited resources available.
