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.
