62 principal aquifers in the U.S. (please see this NAWQA web site for further background). About one-third of those principal aquifers have been the historical focus of water-quality assessments at a regional scale by NAWQA. On January 21, NAWQA released, "Water Quality in Principal Aquifers of the United States," a compendium summarizing groundwater quality trends based upon regional- and national-scale assessments conducted in principal aquifers between 1991 and 2010. The briefing will highlight nationwide and regional findings from that comprehensive report.
- Moderator Patrick Leahy, Executive Director, American Geological Institute
- Barbara Mahler, Ph.D., Scientist for the NAWQA Program
The briefing is free and open to the public. Please RSVP to firstname.lastname@example.org if you plan on attending.
Established in 1991 by Congress, the NAWQA program mission is to produce surface and ground water quality information for Federal and state resource managers.
