InnovationIn my office files there is a xeroxcopy of a letter from O.E.Meinzer to C.V. Theis dated 6November, 1937. It is a critical,three-page single-spacedreview of the classic paper thatwould eventually be publishedas “The significance of the coneof depression in ground-waterbodies” (Economic Geology, v.33, p. 889-902). At the timeMeinzer had already beenGeologist-in-Charge of theUSGS Ground-Water Divisionfor a quarter century, and Theiswas still a relatively young staff

s c i e n t i s t s t a t i o n e d i nAlbuquerque. Among myfavorite passages are:

[they were all men then]

Finally, in a handwritten notenext to the signature block,Meinzer notes that

“I submitted your paper tosome of the men in the office

andfound that it made a veryunfavorable impression. Itherefore made a criticalstudy of it and am returning itto you with numerouscriticisms…”“In the first place it is evidentthat the paper is poorlywritten … there are certaindifficulties in your style thatm a k e i t d i f f i c u l t t ounderstand your papers.Critical reading shows thatback of the confusion oflanguage is somewhat of aconfusion of thought.”“It occurs to me, also, thatyou are not sufficientlyfamiliar with the ground-water literature, or perhapsrather with the results ofstudies that have not yetbeen adequately expressedi n t h e p u b l i s h e dliterature….”

“If youshould decide not to give thepaper at this meeting I willnot object….”

Of these excerpts perhaps themost telling is the 4th, becauseit suggests that Meinzer wasnot yet convinced of the validityof the quantitative approach tothe non-equilibrium problemthat had been introduced twoyears previously in Theis' great1935 paper (TransactionsAmerican Geophysical Union,p. 519-524).I received a copy of thisMeinzer-Theis letter from acolleague in the USGS NewMexico District office in theearly 1980s, when I was still ingraduate school. At the time Ifound it absolutely shocking – itseemed to me as if the “Fatherof Ground-Water Hydrology”was trying to stifle one of hismost brilliant offspring. Now,30 years later, it seems to meemblematic of the nature ofscientific progress. Even thebest of us – and Meinzer was awonder fu l sc ient is t andm a n a g e r – m a y n o timmed ia te l y app rec i a teinnovation, and even trueinnovators like Theis may needextraordinary persistence inorder to convince a criticalmass of their colleagues.

Parkhurst 2012 O.E. MeinzerAward Recipient

c o n t i n u e d t o w o r k f o r t h e U S G Sduring and after college, working on severalgeochemical issues, including the development ofthe PHREEQ model in 1980, with subsequentpublications that have been cited for this award.David continued to work on model development, inaddition to other topics in organic and inorganicgeochemistry. David has produced a large body ofimpactful papers, from which the award committeerecognized four seminal papers as havingsignificantly advanced the science.

In support of David’s Meinzer Award, fourpapers were cited (see insert). These papershighlight David’s work related to the developmentand application of geochemical modelingsoftware. The first paper describes thedevelopment and use of the computer programPHREEQE which models geochemical reactions.PHREEQE can calculate pH, redox potential andmass transfer as a function of reaction progress.

PHREEQE was further advanced with thedevelopment of PHREEQC, as described in thethird paper cited for the Meinzer award.PHREEQC advances the original program toinclude speciation and saturation-indexcalculations, batch and one-dimensional transportcalculations and inverse modeling. The fourth

The second paper cited for the Meinzerdescribes the formulation of a geochemical mole-balanace model that includes a term foruncertainty, great ly enhancing inversegeochemical modeling.

paper also cites the development of a geochemicalmodel, PHAST. PHAST further extendsPHREEQC to a multicomponent, reactive solutetransport model capable of simulat inggeochemical reactions in three-dimensionalsaturated groundwater flow systems.

The deve lopment o f PHREEQE,PHREEQC and PHAST have resulted innumerous publications on geochemical modeldevelopment and application by David and otherresearchers around the world. The user-friendlyenvironment, accessibility, flexibility and power ofthese codes have enabled advances in a variety offields, and are incorporated in at least 7 othercodes. Given these vital contributions tohydrogeology David Parkhurst is this year’srecipient of the GSA Hydrogeology Division’s O.E.MeinzerAward.

The 2012 O.E.Meinzer Award willbe presented toDavid L. Parkhurstof the United StatesGeological Survey( U S G S ) a t t h eH y d r o g e o l o g yDivision luncheon atthe Charlotte GSAmee t i ng . Dav idbegan his career atthe USGS as avolunteer duringhigh school. HeDavid L Parkhurst

He was elected to thisposition in 2006 and continues in this role today,stepping down at the end of the 2012 AnnualMeeting in Charlotte. The secretary/treasurerposition is responsible for coordinating many of theDivision’s activities, managing all financialtransactions including the Division’s variousfoundation funds supporting Division awards,lectureships, and student research programs, andfor maintaining a record of Division business.Brian’s savvy management of Division funds hasallowed our Division to remain in great financialshape throughout recent economic fluctuations,enabling us to grow our principle and maximize ourgrowth fund.

Brian’s contributions to the Division extendbeyond financial management, and includedattending numerous Management Boardmeetings, Annual Meetings, Leadership TrainingWorkshops and on-l ine and in-personManagement Board and GSA Planning meetings.In each of these instances he has sacrificed hisown professional development in order to attend.Brian has also assisted in booking rooms forvarious events during the Annual Meetings, suchas the student reception, distinguished lectures,and ordering the luncheon and reception meals.Brian can also be seen regularly volunteering tohelp out at the luncheon and student reception, inaddition to staffing the Division’s booth in theexhibit hall.

It is clear that Brian is willing to do anythingand everything to serve the Hydrogeology Divisionof the GSA, and we would like to acknowledge hisservice with the presentation of the Burke MaxeyDistinguished ServiceAward.

The 2012 Burke Maxey Distinguished ServiceAward is presented to Dr. Brian Katz. Dr. Katzreceived his B.Sc. in Chemistry from SUNYOneonta and his M.Sc. in geochemistry from theUniversity of Colorado, Boulder. Dr. Katz thenworked for the USGS in Long Island, N.Y. and thenin Maryland. He was accepted into the USGSGraduate School Program, and after completingenvironmental engineering courses at JohnHopkins University, he earned his Ph.D. in geologyfrom Florida State University, where he is now anadjunct professor in the Department of Earth,Ocean and Atmospheric Sciences, in addition tocontinuing to work for the USGS at the Tallahasseeoffice.

Brian’s current research focus is on the useof environmental isotopes and other chemicaltracers to determine sources and chronology ofcontamination in groundwater and springs in karstaquifers, assessing the impact of waterwaterdisposal on groundwater quality, and quantifyinghydrochemical interactions between groundwater

Cardenas is the InauguralRecipient of the Kohout EarlyCareer Award

receiving tenure and promotion to AssociateProfessor in 2011.

Dr. Cardenas’ research began in modeling,developing a model of point bar deposits whileworking towards his MS at UNL. It is noted by hiscitationist that in the acceptance letter from theresulting manuscript Bayani is addressed as ‘Dr.Cardenas’; this was before he had even receivedhis MS, an indication of his bright future ahead.

The research Bayani conducted for his PhDwork focused on modeling groundwater-surfacewater interactions, an area in which he remains anactive and prominent researcher. His use of multi-physics modeling to quantify coupled turbulentchannel flows with heat flow and biogeochemicalsolute transport within the streambedrevolutionized the field; figures from these papersare often used in talks and classrooms around theworld.

While Dr. Cardenas continues to use anddevelop model ing tools for evaluat inggroundwater/surface water interactions, he hasalso explored several other research areas. Heoften combines field, experimental and theoreticalmethods in labs and field sites all around the world.His current studies on coastal aquifers and freeconvection of groundwater near volcanic craterlakes are particularly appropriate for this award, asKohout was a pioneer in the study of density-driven groundwater convection.

Bayani’s accomplishments are many anddiverse, including invited lectures, awards from theAmerican Geophysical Union and NationalScience Foundation, the accomplishments of hisstudents, and the volume of grants he hasreceived. As such, Dr. Cardenas is the perfectinaugural recipient for the Kohout Early CareerAward, and the GSA Hydrogeology Division wouldlike to acknowledge the contributions he has madeto the science in his short time thus far as amember of the community. We anticipate and lookforward to many more years of exceptionalresearch.

The 2012 Kohout Early CareerAward is presentedto Dr. M. Bayani Cardenas of the Department ofGeological Sciences at the University of Texas atAustin. Dr. Cardenas was born in Goettingen,Germany, but grew up in his native country of thePhilippines. He obtained his BS from theUniversity of the Philippines-Dilimann in 1999before going to the University of Nebraska-Lincolnfor his MS in Geology, studying under VitalyZlotnik. Dr. Cardenas and his young family thenmoved to Socorro, New Mexico where hecompleted his Ph.D. with Dr. John Wilson at theNew Mexico Institute of Mining and Technology,supported by the Frank M. Kottolowski Fellowshipadministered by the NM Bureau of Geology andMineral Resources. The Cardenas family thenmoved to Austin, Texas where Bayani started asan Assistant Professor at UT Austin in 2006,

Charlotte 2012: HydrogeologyDivision EventsAs in past years, the Hydrogeology Division will continue its tradition of hosting numerous eventsthroughout the GSA Annual meeting to encourage and foster ongiong and new relationships betweenmembers. The schedule below highlights the Hydrogeology Division events.

Luncheon,Awards and Business Meeting

Birdsall-Dreiss Lecture

Tuesday, November 6 will be a busy day, startingwith the Hydrogeology Division Luncheon andAwards Ceremony beginning at 11:45 am(although the line-up to get in usually startsearlier!), in the Westin Charlotte Grand BallroomC. The Business meeting will follow the lunch andawards in the same location. Tickets for theluncheon can be purchased when you register forthe conference for $43.00; these tickets areusually sold out before the conference and aredifficult to get once the conference has begun. Theluncheon is an excellent opportunity to meet andn e t w o r k w i t h m a n y o f t h e l e a d i n ghydrologeologists at GSA.

Later on Tuesday afternoon is the Birdsall-DreissLecture, given by Jay Famiglietti, from 4:30 pm to5:30 pm in CCC Ballroom Division A. If you havenot had a chance to hear one of his lectures on thistour, this is one of your last chances!

found the Hydrogeology Division to be wonderfullyfunctional, with lots of positive inertia and manycaring members who are always willing to pitch in.I've also learned that some GSA Divisions (which Iwon't name) sometimes have trouble maintaininga website, or putting out a newsletter, orcontributing to the technical program at GSAmeetings. That is definitely not the case in HydroDivision.

Our Joint Technical Program representative AliciaWilson deserves most of the credit for thewonderful Charlotte program; be sure to thank andcongratulate her at the meeting. Ed Harvey was awonderfully organized Chair; I have tried toemulate him as much as possible, have frequentlyrelied on his advice as immediate Past Chair, andlook forward to joining him in the ranks of PastChairs in Charlotte. Andrea Brookfield and MikeSukop make sure that Hydro Division DOES havea useful and functional newsletter and website.Our Secretary/Treasurer Brian Katz, the longest-serving member of the Management Board, hasbeen our institutional memory and will be the verydeserving recipient of the 2012 George BurkeMaxey Distinguished ServiceAward.

Warm regards,

While doing a cursory online search to explore thebackground of the Meinzer-Theis letter discussedabove, I noticed that neither O.E. Meinzer or C.V.Theis has a dedicated Wikipedia entry – thoughthere is a “stub” entry for the Meinzer Award.Other biographical resources are available online,notably a 15-page biography of Theis by hiscolleagues Robert R. White and Alfred Clebschand an encyclopedia.com entry about Meinzer.However, for many of us Wikipedia is becoming afirst resort for information, and some scientificcommunities (e.g. the mathematicians) havemade a concerted effort to memorialize theirhistory in Wikipedia. Should we consider doing thesame?

The Hydrogeology Division is sponsoring or co-sponsoring 52(!) technical sessions, a PardeeSymposium, and two Distinguished Lectures(Darcy and Birdsall-Driess) at the 2012 GSAAnnual Meeting. Other Hydro Division eventsinclude the Student Reception, the Luncheon,Awards, and Business Meeting, two ManagementBoard meetings, and a staffed booth in the exhibithall.

This will be my last “Chair's Corner”, so I want tothank all of you for the opportunity to serve as yourChair, and to particularly thank some of theindividuals who have kept the HydrogeologyDivision running smoothly during my tenure. I've

Or to Tour as 2013 Birdsall-DreissLecturer

Dani Or has been selected as the 2013 Birdsall-Dreiss Distinguished Lecturer. The lectureship isgiven to one person annually by the GSAHydrogeology Division; Or is the 35th GSABirdsall-Dreiss lecturer.Dr. Or is a professor of Soil and TerrestrialEnvironmental Physics and Director of the Instituteof Terrestrial Ecosystems (ITES) in theDepartment of Environmental Systems Science atthe Swiss Federal Institute of Technology (ETH)Zurich in Switzerland. His research focuses onmass and energy transport in porous media, onmechanics of abrupt landslides and avalanches,and on linking physical processes and biologicalactivity in soils. Dr. Or has authored or co-authoredover 170 refereed publications, co-authored abook, and over 270 proceeding papers andabstracts. Dr. Or is Editor in Chief of the VadoseZone Journal, recipient of the Kirkham SoilPhysics Award (2001), Fellow of the Soil ScienceSociety of America (2004), elected chair of the2008 Gordon Research Conference on Flow andTransport in Permeable Media (Oxford, UK), andwas elected 2010 Fellow of the AmericanGeophysical Union. The two Birdsall-Dreisslectures for 2013 will be based on recent findingson the quantitative basis for evaporation dynamics

from terrestrial surfaces and on biophysicalprocesses controlling microbial life in unsaturatedsoils.

Interested institutions should contact Dani Or atto schedule a lecture on one

of the following topics:

Globally, evaporation consumes about 25% ofsolar energy input and is a key driver for thehydrologic cycle, whereby 60% of terrestrialannual precipitation returns to the atmosphere viatranspiration (40 %) and soil evaporation (20%).Quantifying evaporation is important for assessingchanges in hydrologic reservoirs, surface energybalance and climatic processes, and for manyindustrial and engineering applications. Key(1972) commented that “evaporation is acommonly practiced art, but a neglected science” -interactions of evaporating surfaces with internalliquid and vapor transport below and withatmospheric controls above remain largelyempirical. Despite basic similarities, evaporationfrom porous media is significantly different thanfrom free water surfaces due to withdrawal of liquidfrom internal pore spaces and nonlinearinteractions between drying surfaces and the airboundary layer. Porous media propertiesdetermine abrupt transitions from initially highevaporation rate (stage 1) to a slower diffusion-controlled stage 2. This well-documented behavioris attributed to disruption of capillary liquidcontinuity essential for supplying surfaceevaporation. New findings highlight nonlinearbehavior of drying porous surfaces due toenhanced vapor fluxes from remaining activepores as they become increasingly isolated.Increased spacing between active pores underlow atmospheric demand (thick boundary layer)results in significant increase in evaporative fluxper pore that may compensate for the reducedevaporative surface area (progressively drying

diffusional pathways and shapes microbialdispersion patterns. We quantitatively exploredeffects of microscale hydration on biophysicalinteractions affecting microbial dispersion andcontrolling coexistence of competing bacterialspecies inhabiting unsaturated surfaces.The rapidfragmentation of the aqueous phase yields asurprisingly narrow range of hydration-enabledmotility, and marks the onset of flux limiting andheterogeneous diffusion fields that promotecoexistence. Conditions promoting coexistenceoccur under mild unsaturated conditions withinmatric potential values of a few kPa nearlyindependent of soil or rock type. The spontaneousspatial organization of interacting microbialpopulations and formation of consortia shaped bydynamic diffusion fields and trophic interactionsoffer a fascinating and robust level of self-organization that support high diversity found insoil. The resulting length scales for interactionsoffer new insights into biogechemical function ofsoil microbes and could guide bioremediationactivities of the subsurface.

Evaporative fluxes from heterogeneoussurfaces (texture, fractures) are spatially non-uniform as shown by thermal imaging, and oftenlead to enhanced evaporative losses relative toevaporation from uniform surfaces. Implications ofthe findings for estimates of evaporative lossesused in hydrological and climate models will bediscussed.

By some accounts exploring the microbial diversityfound in soils represents an uncharted scientificfrontier at a scope similar to that of spaceexploration. The immense diversity of soilmicrobial life is attributed to the complex andheterogeneous pore surfaces and spaces withhighly dynamic aqueous and chemicalmicroenvironments.

Cape Cod, MA

Congratulations to Dr. David Boutt of theUniversity of Massachusetts-Amherst in being thefirst to correctly identify this photo as the CapeCod research site on the Massachusetts MilitaryReservation (MMR). Congratulations to DariuszChlebica, Mike Chapman, Bob Abrams, MikeFrimpter and Kathryn Hess for also correctlyguessing this location.

This photo was taken during the NovCareconference held in May 2011 at the Cape Cod site.Perhaps Dr. Boutt had an unfair advantage, as healso identifies himself as one of the people at thedrill rig in the far left.

The MMR is a 22,000 acre military facility on thewestern Cape Cod. The MMR is presently thehome to the Camp Edwards army-training site, theOtisAir National Guard Base fighter squadron, theMassachusetts National Cemetary and severalsmaller military and civilian tenants.

The MMR overlies the Cape Cod aquifer,wh ich is composed of most ly sandyunconsolidated sediment deposited at the edge ofretreating ice sheets approximately 15,000 yearsago. Military activiities, primarily from the 1940s-1970s introduced chemical wastes into the CapeCod aquifer. The Impact Area Groundwater StudyProgram is cleaning up contaiminated soil andgroundwater from some of these plumes.

The MMR has been the site of manyhydrogeology research activities, including thefamous large-scale natural gradient tracer testsfrom the early 1990s. These studies looked intothe spatial movements for non-reactive tracers, inaddition to variability of hydraulic conducitivty anddispersion in this heterogeneous aquifer. TheMMR site has been, and continues to be, an activeresearch site for hydrogeologists.

From the Editor....Welcome to the Fall 2012 edition of the Hydrogeologist

. Yes, I am aware that in Munich they celebrate inSeptember, but I’m pretty close.

I’d like to give a shameless plug for the newest addition to theKGS website (my employer). Several members of the GeoHydrosection have recently developed an online tool called the Kansas HighPlains Aquifer Atlas. Although I had nothing to do with it, I encourageyou all to check it out:http://www.kgs.ku.edu/HighPlains/HPA_Atlas/index.html

As usual, forward any comments or article ideas to.

I hope to see you all in Charlotte!
