Philadelphia Awaits Your Arrival!

By Laura Toran & MarkPerson, Co-Chairs 2006Hydrogeology DivisionProgram

There are really too many highlights for this exciting

meeting to summarize in a brief newsletter. We have just asmany sessions (about 35) and abstracts as last years meeting,so the change to an east coast venue has not curbed members’interest in hydrogeology at GSA. I would like to point outthat we are again hosting both the National Ground WaterAssociation Darcy Lecture and the GSA HydrogeologyDivision Birdsall-Dreiss lecture. Eileen Porter, the Darcy

lecture will speak at 5pm onMonday at the end of thesession on Emerging andInnovative Approaches toGroundwater Modeling. Hertalk is: All Models Are Wrong,How Do We Know Which AreUseful? David Blowes, theBirdsall-Dreiss lecture willspeak at 4:30 on Tues as part

of the session on Chemical and Hydrological Interactions inthe Evolution and Control of Coal and Metal Mine Drainage.It is at the end of the poster sessions on Tues so there are noconflicting talks at this time. David’s talk is titled: Predictingand Preventing Acidic Drainage From Sulfide Bearing MineWastes. Both of these talks are in a large lectures hall on thelower level of the convention center – don’t miss them!

The Philadelphia Convention Center.

Dear Hydrogeology DivisionMembers:

Furthermore, in honor of the 150th

anniversary of Darcy’s Law, we willreissue a commemorative version ofthe original Darcy Mug; you won’twant to miss this either. All in all, theAnnual Meeting promises to beintellectually stimulating and loads offun. I truly hope to see you there.

As I end my 1 year term asthe Chair of the Division, I would liketo thank all of you for your support.Scott Tyler will take over as Chair andI trust that he will enjoy the same levelof support and professionalism that Ihave experienced. While our DivisionMembership continues to grow, weare of course a small group in thegrand scheme of things. Perhaps thissense of family is what makes me trulygrateful to call the HydrogeologyDivision my professional home.

I am looking forward to seeingmany of you in Philadelphia. As youwill see later in the newsletter, thetechnical program is outstanding (andlarge!) In addition to the technicalprogram, the Birdsall-Driess and DarcyLectures will be presented along withnumerous great field trips, our awardsluncheon and business meeting, and ofcourse our student reception. Just priorto our awards luncheon on Tuesday,Don Siegel will be doing a kosher-Chinese cooking demo. Plan to arriveearly as you won’t want to miss Donand Scott Bair flipping dumplings filledwith Chinese broccoli, shitakimushrooms, and rice vermicelli. For adonation of just $20.00 you can walkaway with one of Don’s books; you toocan learn to flip dumplings and at thesame time support the Division’s effortsto fund lectures, student research, etc.

Want to know what’s going on within the GSAHydrogeology Division?

Pruess 2006 O.E. Meinzer Award Recipient

O.E. Meinzer Award Papers

by Michael Celia

The 2006 O.E.

Meinzer Award recipientis Dr. Karsten Pruess ofLawrence BerkeleyLaboratory. For morethan 25 years, Dr. Pruesshas been at the forefrontof scientific studies ofcomplex problemsinvolving fluid flow innatural porous media.His work has strongscientific content,important practical value,and has impacted andinvolved many otherresearchers.

Pruess earned his PhD in Theoretical Physics in 1972and arrived at LBL in 1975 as a Research Fellow in theNuclear Theory Group. In 1977, he joined the EarthSciences Division at LBL where he is currently employed.He has authored more than 125 journal papers across arange of important topics and he authored the TOUGH2family of computer codes.

Dr. Pruess’s first hydrogeology research focused ongeothermal systems, which was a natural extension of hisbackground in physics. After working on this problem forthe better part of a decade, Karsten began to work on other

problems involving non-isothermal and multi-phase flow inporous media. These included high-level radioactive wastedisposal, steam injection to remove non-aqueous-phase liquid(NAPL) contaminants, multi-phase flow in fractures, the roleof preferential flow in unsaturated soils, fundamental numericalsimulation methods for multi-phase and unsaturated-zone flowsystems, and the incorporation of geochemistry into non-isothermal multi-phase simulations. Most recently, he hasbeen working on the problem of injection of supercriticalCO

2 for the purpose of carbon mitigation, where the idea is

to capture CO2 before it is emitted to the atmosphere, and

inject it into deep subsurface formations so that it remainsout of the atmosphere for hundreds to thousands of years,or more. Dr. Pruess has taken a leading role in the scientificinvestigations of the hydrogeological aspects of this strategy.He and his coworkers have looked particularly at storagecapacities and the influence of subsurface heterogeneities, atpossible leakage pathways and their impact on the efficacyof the approach, at geochemical responses of the systemand the overall long-term fate of the injected carbon, and atthe complex role of phase-change and thermodynamics onpossible catastrophic releases to the land surface.

Dr. Pruess embodies the best in research and scientificstudy: he produces outstanding science, he works onproblems that have tremendous societal impacts, and he doesso with humility, grace, and quiet confidence. For thesereasons, the GSA Hydrogeology Division presents its 2006O.E. Meinzer Award to Dr. Karsten Pruess.

Bahr Receives Distinguished Service Award

By Janet Herman

The award for

Distinguished Service ispresented to Jean M. Bahr inrecognition of her exceptionalservice to the profession ofhydrogeology. The awardspecfically acknowledges herpropensity for unconditionalcommitment and zealousefforts on behalf of others,including students,professional geoscientists,and citizens.

Serving as Chair ofthe Division, Jean didn’t finishher year satisfied with a wellattended annual meeting, a fine technical program, and asuccessful awards ceremony. Instead, she followed thateffort by transforming the Student Reception into a not-to-be-missed extravaganza of professional networkingaccompanied by a wealth of door prizes that went beyondwhat any previous Chair had even imagined. This receptionis now the envy of all other GSA Divisions. Having set “thebahr” for future Past Chairs of the Division, she then movedon to serve as Birdsall-Dreiss Distinguished Lecturer. Sheused a 14-month time-span to deliver 64 lectures, but in sodoing enriched the Division in novel ways. First, she didn’tdrain the lectureship budget because she drove to most ofher venues in her hybrid car. Second, she followed her serviceby conceiving and executing a fund-raising effort that willcarry the Distinguished Lectureship into the future. Shefollowed her tour of duty as Lecturer by immediately signingon to GSA Council where she has been a friend of ourDivision while also invigorating the Society. Add in earlierservice adjudicating the Meinzer Award and contributing toseveral Society-level committees and we recognize Jean’sservice to GSA as being significant and uninterupted since1994, just one year after earning tenure.

Do not believe for an instant that Jean was doingnothing but GSA service during this period. She wascontributing to the National Research Council, initially asmember and then as chair of “the Everglades” committee

addressing complex and contentious issues at the intersectionof society and water resources. She was evaluating worthyresearch for funding on multiple National ScienceFoundation panels thereby impacting the future direction ofhydrogeology. She is also Full Professor and Chair of herhome department – Geology and Geophysics at Universityof Wisconsin – where she directs student research, teachesclasses, and chairs faculty meetings. Not content to influencejust future generations of hydrogeologists, she invests energyin guiding women to pursue their interests in various fieldsof science and engineering through an innovative residentiallearning program.

Do not believe for an instant that Jean was doingnothing but professional work during this period. She hastime to showcase the roof of her home as an electricitygenerator – nudging others toward environmentalresponsibility, to celebrate her love for her parents –reminding us of the importance of family, and to supporther many many friends – enriching those of us lucky enoughto know Jean Bahr.

For her lasting impact on the Division and its presentand future members as well as the wider community ofgeoscientists and citizens, the Hydrogeology Division takesgreat pride in presenting Jean M. Bahr with the DistinguishedService Award for 2006.

Bridget Scanlon

of the Bureau ofEconomic Geology,University of Texas atAustin (UT), hasbeen selected as the2007 Birdsall-DreissD i s t i n g u i s h e dLecturer, sponsoredby the GSAH y d r o g e o l o g yDivision. The Bureauof EconomicGeology is one ofthree units within thenewly formedJackson School ofGeosciences. Host

institutions may select one of two lectures that Dr. Scanlonwill present for audiences interested in broad aspects of waterresources. The topics are ecological controls on water cycleresponse to climate variability and impacts of land use andland cover change on water resources.

Dr. Scanlon received a B.S. in Geology at Trinity College,Dublin (Ireland) and completed her M.S. at the Universityof Alabama, performing karst fieldwork in Ireland. Her Ph.D.at the University of Kentucky (Lexington) involved flow andtransport studies in karst. She joined the Bureau of EconomicGeology in 1987 and currently holds the position of SeniorResearch Scientist. At the Bureau she leads a research groupwhose primary objective is to assess sustainability of waterresources, including both quantity and quality, within thecontext of climate variability and land use/land cover change.Studies integrate physical, chemical, and isotopic analysesand numerical modeling. Much of the research focuses onimpacts of climate variability (ENSO) and conversion ofnatural ecosystems to agriculture on groundwater rechargein semiarid regions. Impacts of natural and anthropogenicsources of contamination, including nitrate and arsenic, onwater quality are also addressed in many of the group’sresearch studies. Dr. Scanlon has taught Vadose ZoneHydrology in the Departments of Geological Sciences andEnvironmental and Water Resources Engineering at UT. Shehas participated in focus groups on global groundwaterrecharge issues for the International Atomic Energy Agency,

as well as serving on National Academy of Science (NAS)committees related to low-level and high-level radioactivewaste disposal. Dr. Scanlon currently serves on an NAScommittee on Integrated Observations on Hydrologic andRelated Sciences.

To request a visit to your institution, contact BridgetScanlon, Bureau of Economic Geology, Jackson School ofGeosciences, University of Texas at Austin, J. J. PickleResearch Campus, Bldg. 130, 10100 Burnet Rd., Austin,TX 78758-4445; 512-471-8241; orbridget.scanlon@beg.utexas.edu. The deadline for requestsis November 31, 2006. The Hydrogeology Division isparticularly interested in including liberal arts colleges in theitinerary. The Division will pay transportation expenses, andthe host institution will provide local accommodations.

Talk Topics

Implications of Climate Variability forGroundwater Resources and Waste Disposal inSemiarid Regions—A Look at EcologicalControls from Annual to Millennial Timescales

Understanding impacts of climate variability ongroundwater recharge is essential for management of waterresources and waste disposal. Semiarid regions areparticularly vulnerable to climate variability because low soil-water contents provide little buffering against dry climateextremes. Water scarcity is a critical issue in these regionsbecause of limited supplies and increasing demand associatedwith greater population growth relative to wetter regions.Approximately 40% of the U.S. population growth between1960 and 2000 occurred in semiarid states of thesouthwestern United States. Potential contaminant transportby recharge to groundwater is a significant concern becausedeserts are favored sites for waste disposal; for example,the U.S. high-level nuclear waste site at Yucca Mountain,Mojave Desert, Nevada. A key question, is How do climatevariability and related vegetation dynamics impactgroundwater recharge? The importance of linkages betweenecology and hydrology is being increasingly recognized inthe emerging field of ecohydrology.

This talk will explore the role of vegetation dynamicsin regulating the impact of climate variability on groundwater

Four years ago the Hydrogeology Division began

a concerted effort to bolster the interest-bearing accountswhich support the Birdsall-Driess Distinguished Lectureship.In this time, the Management Board has appealed fordonations in order to increase the principal in these accountsand thereby increase the interest-generated revenuesupporting future lecture tours.

To date, there have been 189 donations totaling$46,455. Of these, 36 donations totaling $29,299 havecome from former Birdsall-Dreiss lecturers through a specialmatching-funds appeal. The remaining 153 donations totaling$17,156 have come from the division membership at large.

Many division members responded to an initialappeal to pledge a contribution of $25 per year over fouryears. If you are one who made this pledge, thank you bothfor your past contributions and for following through withyour final installment. Hopefully you share in a sense ofcollective pride among those of us who have joined togetherto help. Please give very strong consideration to continuingyour $25 contribution in future years, and perhaps making itan annual tradition of giving in support of the lectureship andthe division, your professional home.

Our efforts to increase the principal in the lectureshipaccounts, along with the recent increase in interest rates,

Report on Birdsall-Dreiss Fundraising

By Bob Ritziand a recent increase in Division dues, will together createbetter funded lecture tours in the near future. However, muchmore is needed in order to establish the level of interestincome and support that the distinguished lecture tour trulydeserves. We have taken some steps in the right direction,but please look for future appeals and respond to them aswe continue work towards putting the lectureship on a firmfinancial foundation.

If you have not yet joined us in helping to supportthe Birdsall-Dreiss Lectureship, please do so now. Donationscan be made in any amount and pro-rated over any numberof years. Donations can be made through the GSAFoundation at: https://rock.geosociety.org/donate/donate.aspor by calling Joan Bell, GSA Foundation, (303) 357-1067.When making a contribution, please clarify that you arecontributing to the Birdsall-Dreiss Lectureship Funds. Inreality there are two separate accounts (the Birdsall Fundand the Dreiss Fund), but in practice they are treated asone. They are listed separately on the Foundation’s webpage pull-down menu under “Where do you want yourcontribution to go?” You may make your full pledge to oneor the other of these funds, or split it between them. Any ofthese approaches will have the identical, positive effect insupporting the lectureship.

Thank you for your support!

recharge. Climate variability at interannual timescales isdominated by the El Niño-Southern Oscillation (ENSO), acoupled atmospheric-oceanic cycle that increases winterprecipitation in the southwestern U.S. ENSO cycles wouldtherefore be expected to increase groundwater recharge.Results from a unique field data set from weighing lysimeters(large, soil-filled concrete containers) beneath nonvegetatedand vegetated systems in the Mojave Desert, Nevada,however, unequivocally demonstrate that vegetation dynamicscontrols the impact of ENSO on groundwater recharge. Thelong-term lysimeter (8-yr) record fortuitously included thelargest El Niño (1997–1998) of the last century. Thelysimeter data indicate that rapid increases in vegetationproductivity in response to 2.5 times normal winterprecipitation reduced soil-water storage to half that in thenonvegetated lysimeter, thereby precluding deep drainagebelow the root zone that would otherwise result ingroundwater recharge. Vegetation dynamics providesnegative feedback to ENSO precipitation. Satellite dataallowed quantification of biomass productivity over largeregions and provided regionalization of the “point scale”lysimeter results. Chloride and pressure-head profiles in thickunsaturated zones at sites across the southwestern U.S.provide natural archives of past conditions. These archivesindicate that similar feedbacks have minimized interstreambasin-floor recharge since the last glacial period, 10,000 to15,000 years ago. Native plants maintain dry soil conditionsand upward soil-water flow across broad regions. Strongcorrelations between satellite-based vegetation productivityand interannual precipitation variability related to ENSO indeserts in Australia, South America, and Africa indicate thatthe processes described in the southwestern U.S. may applyto deserts globally. The two-way coupling between the watercycle and vegetation dynamics is critical in controlling howclimate variability influences water resources, with importantimplications for waste disposal in semiarid regions.

Impacts of Changing Land Use and LandCover on Subsurface Water Resources

Most widespread changes in land use and land coverhave occurred because of agricultural expansion. In the last300 years, cultivated cropland has increased almost 70 foldin the U.S. and about 5 fold globally. Total irrigated agriculturehas doubled globally in the past 4 decades, and agriculturallands are projected to increase ~20% globally in the next 50years. Irrigated agriculture accounts for about 70% of globalwater withdrawals and 90% of global water consumption.

What impacts have these land use/land cover changes hadon water resources?

This talk will show that measurements of energystatus, chemical composition of pore water above the watertable (the vadose zone), groundwater levels, and groundwaterquality provide an archive of system response to past landuse/land cover changes. The presentation will focus on theTexas Southern High Plains, which is one of the largestagricultural areas in the U.S. This region consists of 44%natural rangeland, 44% nonirrigated (rain-fed) agriculture,11% irrigated agriculture, and 1% other. Although irrigatedland use represents only 11% of the area, it accounts for94% of total water consumption. Cultivation of rangelandshas changed the system from discharging throughevapotranspiration to recharging. Evidence of discharge (norecharge, upward water movement) under natural rangelandecosystems includes upward hydraulic-head gradients, highchloride concentrations, and no change in groundwater levelsover time. These natural rangelands have been dischargingsince Pleistocene times (~10,000 to 15,000 yr). Rechargeunder rain-fed agricultural lands is shown by downwardhydraulic-head gradients, high matric potentials, low chlorideconcentrations, and rising groundwater levels. Groundwater-level rises have ranged from 2 to 23 m and averaged 7 mover a 3,400-km2 area of predominantly rain-fed agricultureduring the last few decades, indicating recharge rates from 5to 50 mm/yr (median 21 mm/yr, 5% of precipitation). Changefrom discharge to recharge conditions reflects long fallowperiods (~7 months/yr) associated with cultivation. Rechargeunder irrigated agricultural lands is shown by downwardhydraulic-head gradients and high matric potentials. Lowirrigation rates (0.3 to 0.6 m/yr) in this region result inaccumulation of chloride and nitrate in shallow soils that mayultimately cause soil salinization. Large groundwater-leveldeclines (as much as 75 m) under irrigated areas indicatethat irrigated agriculture is not sustainable. Thick unsaturatedzones under natural rangelands contain a reservoir of saltsthat are mobilized by recharge caused by cultivation, resultingin degradation of groundwater quality (for example,increased salinity, nitrate, and perchlorate). Results from landuse/land cover changes in this region will be compared withthose from other regions globally. Although past land-usechanges had unintended impacts on the water cycle, acomprehensive understanding of these impacts could be usedto alter land use/land cover for better management of waterresources. Further increases in water resources may beachieved through expansion of rain-fed agriculture withpotentially minimal negative environmental impacts.

Geosphere is an entirely electronic publication,

introduced by the Geological Society of America in 2005.The creation of Geosphere was largely motivated by a desireto include the state of the art in scientific visualization andanimation within published articles. The second volume ofGeosphere, published this year, has aspecial collection of papers on reactivetransport.

The special collection is anoutgrowth of a session held at the 2004annual meeting on the topic of “ModelingFlow and Transport in Chemically andPhysically Heterogeneous Media.” Thesession included 23 presentations (GSAAbstracts with Programs - Vol. 36,No. 5). It was decided that the scientificcommunity would benefit from thedevelopment of peer-reviewed articlesfrom among the talks given in the session,and that the animations and othergraphics would especially appropriatefor publication in Geosphere. Eightarticles were contributed to the specialcollection and have been published onan ‘as-ready’ basis. The articles areorganized within the journal as follows:

NGWA and GSA:Collaborating in Pursuit of Scientific

Advancements and Good Data

By Vicki Kretsinger, AGWSE Past Chair,NGWA/GSA Science Liaison

As an Associated

Society of theGeological Society ofAmerica (GSA), theNational GroundWater Association/Association ofGround WaterScientists andEngineers (NGWA/AGWSE) is pleasedto co-sponsor twosessions at the 2006GSA Annual Meetingand Exhibition in

Philadelphia, Pennsylvania. Kudos to Rob Young, of WesternCarolina University, 2006 Technical Program Chair, alongwith Laura Toran of Temple University and Mark Person ofIndiana University, Hydrogeology Program Co-chairs, forassembling a great technical conference on behalf of GSA’sHydrogeology Division!

Collaborative activities between GSA and NGWA/AGWSE are important for many reasons. Now is anespecially important time for such collaborations because ofthe opportunities created to bring together the sciencecommunity to discuss the science and data needs relating todeveloping a better understanding of future groundwateravailability. In a recent member survey conducted by NGWA,it was learned that among AGWSE members, 70 percentreported being “somewhat to very challenged” in theirprofessional work by the issue of the sustainability of groundwater. Through NGWA’s Government Affairs Committee andits annual Fly-In, NGWA has been trying to increasegroundwater awareness and the need for good groundwaterdata on Capitol Hill. Bev Herzog, Chair of the AGWSEDivision and Assistant to the Chief for EnvironmentalInitiatives of the Illinois State Geological Survey, recently

Vicki Kretsinger

learned that groundwater sustainability is important toSpeaker of the House Dennis Hastert. The Speaker calleda press conference in a small town in Kane County, justwest of Chicago and part of Hastert’s district, to announce$1.4 million in grants to the county for water resourcesplanning. Bev reports that most of these funds are going foran ongoing study by the Illinois State Geological Survey andthe Illinois State Water Survey to map the aquifers, monitorground water levels and quality, and model the groundwatersystem beneath the county as a basis for water resourcesplanning. The remainder will go for floodplain mapping. Inmaking the announcement, Hastert stated, “Given itsincredible growth, Kane County must provide an additional60 million to 80 million gallons of water per day to serve400,000 additional residents by the year 2030. This federalinvestment will allow the county to examine how to makethat happen in a way that is cost-efficient and environmentallyresponsible.”

The two NGWA co-sponsored sessions promotethe spirit of GSA’s theme, “The Pursuit of Science”, andalso, promote the effective collection, analysis, andapplication of good data, including formulation of conceptualmodels and development and calibration of numerical models,to address current and future groundwater quantity andquality issues. A related session, “Groundwater Availabilityand Its Sustainability” (Topical Session 69), convened byBill Alley and Kevin Dennehy of the U.S. Geological Survey,also speaks to these objectives, including groundwatermonitoring and assessment to address issues of the long-term sustainability of aquifer systems at the regional scale,including storage depletion, water-quality impacts, landsubsidence, and streamflow depletion.

One of the NGWA co-sponsored sessions at the2006 GSA annual meeting is “Water-Quality Issues in Sole-Source and Principal Aquifers in the U.S.” (Topical SessionT25) which is being co-sponsored by GSA’s HydrogeologyDivision and NGWA/AGWSE and organized by Brian Katzand Mike Focazio of the U.S. Geological Survey (USGS)in Florida and Virginia, respectively. In recent years, concernshave emerged about water quality in many of the 62 principalaquifers in the U.S. In some of these systems, sole-sourceaquifer designations have been used to protect drinking water

supplies especially where few or alternative sources of waterexist. This session highlights research on anthropogenic andnatural factors that control water quality in sole-source andprincipal aquifers in the U.S.

A second session co-sponsored by GSA’sHydrogeology Division and NGWA/AGWSE is “Emergingand Innovative Approaches to Groundwater Modeling”(Topical Session T66). This session, convened by AbeSpringer of Northern Arizona University and Linda Zhangof the University of Michigan, focuses on the evolution andwidespread application of groundwater models andinnovative approaches in modeling. Session presentationswill highlight innovative approaches in development,application, effective parameter determination, uncertaintyof models, and other topics. NGWA’s 2006 Darcy LecturerEileen Poeter, currently a Professor of Geological Engineeringat the Colorado School of Mines and Director of theInternational Ground Water Modeling Center, will provideher Darcy Lecture “All Models Are Wrong: How Do WeKnow Which Are Useful?” in coordination with this session.Eileen’s lecture will presented on Monday October 23 at5:00 pm and details how the groundwater profession todayis searching for appropriate approaches to developingconceptual models, evaluating which are useful, anddescribing the uncertainty associated with their predictions.
