Well- established techniques such as using stable isotopes of hydrogen and oxygen as markers of water source have been applied in water resource investigations for several decades. Isotope methods are powerful tools when applied to the intractable problems of source attribution for the most common groundwater contaminants, including nitrate, VOCs, and perchlorate. Radioactive isotopes can be used to determine groundwater age, or the time since water entered the saturated zone, which has important implications for delineating groundwater or contaminant flow pathways, identifying recharge areas, and providing a measure of aquifer vulnerability. GRA seeks to provide a forum for disseminating proven methods, practical applications, and problem- solving techniques involving isotopes and groundwater investigations. Join us March 28 and 29, 2007 at the Hilton Hotel in Concord, California for the 3rd Event in GRA's Tools and Technologies Series. March 28 Isotope Methods for Groundwater Investigations Course Instructors: Dr. Carol Kendall (U.S. Geological Survey) and Dr. Jean Moran (Lawrence Livermore National Laboratory) Check for future updates about the short course on GRAs web site at http://www.grac.org/isotope.asp March 29 Applications of Isotope Tools to Groundwater Studies Symposium Symposium sessions will cover a variety of topics, including but not limited to: Surface Water Groundwater Interaction Tracing artificial recharge at surface spreading sites Use of isotopes to monitor aquifer storage and recovery (ASR) Tracking stream recharge along losing stream reaches Induced recharge via pumping Isotope tracers in areas of groundwater banking Use of isotopes to examine biogeochemical processes in the hyporheic zone Examining vadose zone transport using isotope methods Contaminant Transport and Geochemical Evolution of Groundwater Multi-tracer or multi-isotope studies Nitrate source attribution using isotope tracers Characterization of nitrogen fate, transport and cycling in the saturated and vadose zones Perchlorate source attribution using isotopes of Cl and O Use of sulfur, carbon, boron or halogen isotopes in fate and transport studies Heavy stable isotopes (e.g., Cr, Pb), or radiogenic isotopes (Sr, U, etc.) in environmental forensics applications Isotope methods for examining multi-component mixtures Aquifer Vulnerability and Water Residence Time Age dating groundwater using radioactive isotopes (e.g., tritium (3H), 3H-Helium, 14Carbon); application of other groundwater age tools (CFCs, SF6, 4Helium) Using groundwater age to validate or calibrate flow and transport models Identifying paleowater using long-lived isotopes and other age/ climate proxies Applications of young groundwater tracers in active recharge areas Tracer techniques for examining groundwater mixing/dispersion Communication of results from isotope studies to clients, sponsors, purveyors, and the public Experts from academia, consulting, regulatory agencies and industry will participate in moderated speaker sessions and posters sessions. The combination of invited speakers and experts from key areas, along with talks chosen from submitted abstracts, will make this an important event for all professionals considering application of isotopic techniques in groundwater investigations. Abstracts for Papers and Poster Presentations at the Symposium GRA welcomes submittals of abstracts for papers and poster presentations on any topic related to the use of isotopes in groundwater investigations. The deadline for submitting an abstract for a Paper or a Poster Presentation is January 26, 2007. Please feel free to contact Bill Motzer (510-595-2120 or [log in to unmask]) or Tom Mohr (408-265-2607 extension 2051 or [log in to unmask]) if you would like to discuss your topic for this Symposium before submitting your abstract, or if you have any questions. Student Poster Competition GRA welcomes poster submissions describing recent research in any of the topic areas from undergraduate and graduate students. Prizes for the best student posters will be awarded! First prize - $300 Second prize - $200 Third prize - $100 Poster presentations will take place during an evening reception on March 28th. Winners will be announced during lunch on March 29th. Students, submit your poster abstract according to the guidelines given below. Guidelines for submitting an abstract for a Paper or Poster Presentation: > Word 9.0 documents are preferred. > Indicate the preferred presentation method (paper or poster) and the topic of the abstract > Abstracts must be one page in length or less, and should be titled and include all contributing authors' names and affiliations. Please identify the name of the person who will be presenting the paper or poster, and add biographical sketches of the authors as a second page. The sketches should be 50 words or less in paragraph form, and full mailing and e-mail addresses and phone and fax numbers must be included. > Margins should be 1-inch top, bottom, and right side and 1 Ό-inch left margin.
