This fifth workshop, discussing three-dimensional (3D) geological mapping for groundwater applications, is part of an ongoing series that began in 2001. A focus
of all the workshops has been the development of techniques to optimize internal consistency and to fully integrate 3-D stratigraphic with hydrostratigraphic models that can be used directly for hydrogeologic modeling. Workshops have emphasized the
need for high-quality data, the procedures for reconciling often disparate and plentiful archival data, and the obvious realization that the better the geological model, the greater the probability that subsequently derived groundwater flow models
will be as accurate as possible.
Studies focused on the generation of 3D geologic models of the near surface have dominated the previous four workshop proceedings, as the workshop organizers strove to maintain this as a central focus. In
addition, there has been an attempt to maintain connection with the needs of the groundwater community. Therefore, several groundwater modeling presentations have emphasized informational needs for producing viable groundwater flow models.
importantly, each successive workshop has adapted to and reported on continually evolving and newly emerging software applications for basic mapping and visualization, as well as innovations in data management strategies. There has also been a
conscious effort to continually include perspectives that allow workshop participants to expand their horizons and consider other, perhaps less traditional, methods and applications for their mapping and modeling efforts. Along these lines, an
increasing number of Europeans involved in 3D modeling have become regular workshop participants, and have shared their often unique experiences that have direct application to North American issues. Workshop presenters dealing with 3D mapping of
bedrock, and supporting energy developments, have provided insight regarding their model building techniques and applicable interpretive uses. Finally, although workshop focus has been on 3D geologic modeling for groundwater applications, we
continually have sought other applications and interpretive uses of geological models, as well as mechanisms to improve the understandability and accessibility of geological information. We realize that communicating the results of geological mapping
must go beyond the technical level, and that geological work must be relevant and understandable by the general public, particularly if we expect to receive continued and increased funding for mapping activities.
