Mission
The Deep Ground Water Investigations Interest Group consists of NGWA members including, but not limited to, geologists, engineers, and water well contractors, whose activities involve investigation of ground water in environments deeper than normal, defined here as depths of 500 or more feet requiring the use of equipment and/or methods not commonly used for routine environmental investigations.
The objective of the DGWIIG is to address the methods and issues associated with such deep drilling.
The mission of the DGWIIG is to promote communication and actively disseminate information pertaining to issues related to deep ground water investigations, e.g., the design, construction, sampling, and utilization of deep wells.
Goals and issues
Examples of issues to be addressed by the group include, but are not limited to:
- Project planning and cost estimating of deep ground water investigations and techniques (i.e., finding the right contractor for the job)
- Technical aspects of deep ground water investigations, particularly:
- Borehole drilling, logging, and sampling methods
- Well construction and operation
- Well sampling equipment and methods
- Well testing and hydrogeologic characterization
- Aquifer protection
- Current regulatory guidelines pertaining to deep ground water investigations
- Lessons learned from successful and unsuccessful deep ground water investigations
- New and emerging technologies for deep ground water investigations
- How to cost effectively acquire and interpret data from deep wells and deep ground water regimes
- Water supply from, or injection into, deep ground water
- Environmental, geotechnical, and other investigations of deep ground water
- Developing resources and references for evaluating technologies and methods associated with deep ground water investigations (i.e., what types of equipment work best and when).
Issues may be addressed through such activities as presentations of topical sessions at NGWA conferences, an e-list discussion group, publication of journal articles, and by posting information to the NGWA Web site.
