Modern societies have increasing demands for contaminant remediation and a continued supply of potable water. This is particularly the case in the densely populated and industrialized parts of North America and Europe. Coping with the demand, however, requires optimal geologic mapping and modeling methods, and for hydrogeologists to generate improved model scenarios using the best available geological information. Unfortunately, there is often a lack of collaboration between geologists and hydrogeologists. Therefore, geological complexity and understanding is often under-represented in many groundwater models.
