ABSTRACT

To be an effective contractor or operator for the treatment of water wells that are

loosing their production capacity and/or failing to deliver an acceptable water

quality, there are aspects of treatment that can be considered more of an art than a

science. Modeling water wells and hydrological impacts may appear to be

mathematically precise but if that model does not contain all of the factors affecting

the water well then it becomes nothing more than guesswork. Unfortunately pretty

well all modeling exercises associated with the geohydrological performance of

wells ignores the biological factors that are critical components in plugging and

degenerating water quality issues. Groundwater is not a sterile environment and

flows through porous media or fractures which will be impacted by the biological

activity occurring both on the surfaces and in the flowing water itself.
