ABSTRACT
A hydrogeological conceptual site model (CSM) is a description of various natural and anthropogenic factors that govern and contribute to the movement of groundwater in the subsurface. Simply put, it is the answer to the following key questions:
• Where is the groundwater coming from? • Through what type of porous media is it ¡owing? • How much of it is there, and how fast is it ¡owing? • Where is it going? • How did the groundwater system behave in the past, and how will it change in the
future based on both natural and anthropogenic in¡uences?
