2013 NGWA Groundwater Summit

April 28-May 2, 2013 San Antonio, Texas

Greetings, friends and colleagues! On behalf of the National Ground Water Association and the Groundwater Summit Program Committee, we welcome you to the 2013 NGWA Summit. You are participating in the only annual technical conference that is devoted solely to advancing groundwater science, technology, and policy.

We express our sincere gratitude to all those who have contributed to make this event possible, especially our program committee members Billie Arceneaux, Jim Butler, Alan Dutton, Leroy Goodson, Scott King, David Kreamer, David Lipson, Mary Musick, Jack Sharp, and Joe Yelderman; NGWA’s hardworking staff; our valued cosponsor, the International Association of Hydrogeologists; the instructors for our technical courses; field trip guides; keynote and guest speakers; session moderators; platform and poster presenters; distinguished industry leaders; the NGWREF Darcy, NGWREF McEllhiney, and the Birdsall-Dreiss distinguished lecturers; sponsors; and the many others who are contributing to this year’s Summit.

This on-site program contains a comprehensive agenda and additional details on this event. We’re pleased to bring together professionals, academics, and government agency personnel from around the world who are involved in the many disciplines and aspects of the groundwater industry. Attendees will share knowledge, learn from each other, meet new friends, and enjoy scenic San Antonio, Texas (a city that gets most of its water from groundwater).

We are pleased to have you join us for the 2013 NGWA Summit. Be a part of this exciting event!

Robert Mace, Ph.D., and Kristine Uhlman, RG Cochairs, Summit Program Committee

Conference HighlightsThis year’s Summit program — with more than 192 presenters — offers 32 platform presentations in nine tracks, 25 posters in two sessions, two panel presentations, a half-dozen “twilight” sessions, and more.

Keynote AddressQuenching ‘The Big Thirst’ by Charles FishmanMonday, April 29 • 10:30-11:50 a.m.Charles Fishman is the keynote speaker for the 2013 NGWA Summit — The National and International Conference on Groundwater.

Fishman, an award-winning reporter who has spent the last several years trying to understand water issues around the world, is the New York Times bestselling author of the book, The Big Thirst: The Secret Life and Turbulent Future of Water. Focusing on society’s relationship with water, his message is cautionary, but optimistic — there is still no reason for a global water crisis as there is more than enough water . . . it just has to be used smartly.

Since The Big Thirst was published, Fishman has spoken about water issues at Wharton School of the University of Pennsylvania, the University of Michigan, the Massachusetts Institute of Technology, and the U.S. State Department. He also recently penned a thought-provoking op-ed article on the current drought encompassing much of the United States.

Book signing: Charles Fishman will be signing books on April 29 from 12:00-2:00 p.m. following his presentation.

Guest Lecturers2013 NGWREF Darcy Lecture presentationTuesday, April 30 • 9:40-10:50 a.m.Dr. David L. Rudolph will present his 2013 NGWREF Darcy Lecture, “Managing Groundwater Beneath the Agricultural Landscaper.”

Gain insight on how the nature of groundwater quality has been impacted from agricultural land-use practices, at both local and regional scales, with a specific focus on nitrate and microbial indicator species.

Dr. Rudolph is a Professor in the Department of Earth and Environmental Sciences at the University of Waterloo specializing in regional hydrogeology and groundwater protection and management. Dr. Rudolph’s works extensively in areas related to the regional management of groundwater resources, participating with provincial and municipal authorities in the development of groundwater protection strategies. Recent research applications have focused on assessing the impacts on shallow groundwater and surface water quality from agricultural land-use practices and the evaluation performance of Beneficial Management Practices.

2013 NGWREF McEllhiney Lecture presentationTuesday, April 30 • 10:50 a.m.-12:00 p.m.John Jansen, Ph.D., PG, will present his 2013 NGWREF McEllhiney Lecture series, “Keeping the Pump Primed: Aquifer Sustainability.”

No one can control, manage, or sustain what is not measured, so monitoring is the first step needed to ensure success. In terms of ground-water, monitoring can identify aquifers being used in an unsustainable manner and that information can then be used to find remedies to sustain the systems, as well as the industries and businesses that rely on them. One example of this, which will be discussed in this lecture, is the deep sandstone aquifer of northern Illinois and southeastern Wisconsin, where decades of overpumping have created one of the largest cones of depression in the world. Both states have conducted detailed studies of the aquifer and have begun regional planning to control the human and environmental impacts. (The McEllhiney Lecture Series is made possible by a grant from Franklin Electric.).

Dr. Jansen has a B.S. in Geology and a M.S. and Ph.D. in Geological Sciences with an emphasis in hydrogeology and geophysics. He is the Senior Managing Hydrogeologist for Cardno ENTRIX and the lead author of the chapter on borehole geophysics in the third edition of Groundwater and Wells. He is a Professional Geologist in seven states, and a Registered Geophysicist in California. He currently is the NGWA representative on the Advisory Council on Water Information and was on the Board of Directors for the NGWA Scientists and Engineers Division from 2005 through 2007.

2013 Birdsall-Dreiss Lecture presentationWednesday, May 1 • 10:40-11:40 a.m.Dr. Dani Or will present his 2013 Birdsall-Dreiss Lecture, “How Do Porous Terrestrial Surfaces Control Evaporation into the Atmosphere?”

Dr. Dani Or is a professor of Soil and Terrestrial Environmental Physics and Director of the Institute of Terrestrial Ecosystems in the Department of Environmental Systems Science at the Swiss Federal Institute of Technology Zurich in Switzerland. His research focuses on mass and energy transport in porous media, on mechanics of abrupt landslides and avalanches, and on linking physical processes and biological activity in soils. Or has authored over 170 refereed publications, co-authored a book, and over 270 proceeding papers and abstracts. Or is Editor in Chief of the Vadose Zone Journal, recipient of the Kirkham Soil Physics Award (2001), 2004 Fellow of the Soil Science Society of America, chair of the 2008 Gordon Research Conference on Flow and Transport (Oxford, UK), and 2010 Fellow of the American Geophysical Union.


Optional Short CoursesDrilling Fundamentals for Hydrogeologists (#373) April 28• Regency Ballroom West 5Presenters: Marvin F. Glotfelty, RG, and Art Becker, MGWC, CPG

This one-day course is designed to acquaint — or reacquaint — you with:

•Variousdrillingmethods•Welldesignconcepts•Designcalculations•Troubleshootingtechniques.

In addition to the nuts and bolts, health and safety considerations will be addressed, as well as building rapport with other groundwater professionals at the drill site and on the project.

Practical Tracer Testing Techniques for Site Characterization and Remediation System Design (#501) April 28 • Regency Ballroom West 6Presenters: Elizabeth Cohen, Ph.D., and Craig Divine, Ph.D.

This one-day course focuses on the practical use and application of tracers by practitioners at remediation sites, including guidance on the use of tracers to characterize aquifer injectability, understand reagent distribution and utilization, quantify contaminant transport and degradation, and provide a basis for the design and optimiza-tion of in situ remediation systems.

While tracers have been broadly utilized in hydrogeologic and hydrologic studies for many years to understand solute transport phenomena in porous media and fractured rock aquifers, until recently, they were mostly used in research settings applied and, only infrequently employed, by consultants and practitioners at typical contaminated sites.

Now, however, due in large part to the recognition that the success of many in situ remedial strategies is tied to local-scale hydrogeo-logic conditions, reagent distribution, and contaminant transport behavior, tracers are increasingly becoming a standard and cost-effective hydrogeologic characterization tool. They are being used by consultants to obtain basic aquifer characterization information and support development of conceptual site models, calibration of numerical flow and transport models, evaluation of contaminant-related risk, and remediation system design and assessment.

Additionally, this course highlights examples of how tracers can be used to measure contaminant flux, assess LNAPL mobility, and evaluate hydraulic capture.

Basic terminology and concepts will be covered, as well as tracer materials and analytical methods; health, safety, and regulatory issues; test design and data interpretation concepts; and specialized applications and new developments.

Applications of Groundwater Geochemistry (#485) May 2-3 • Maverick RoomPresenters: Bill Deutsch and Patrick Longmire, Ph.D.

This two-day course will provide you with the knowledge you need to evaluate contaminant migration and design remediation systems based upon the geochemical parameters of your site.

While a basic understanding of geochemical concepts is a good start, knowing how contaminants will behave in a variety of geochemical settings is vital in conducting site assessments or designing an effective remediation project.

Conditions resulting from groundwater and aquifer/soil interactions will be discussed and the effects of introducing a variety of con-taminants will be examined. Case studies will be used to explain data collection requirements, laboratory analytical methods, and interpre-tation of data. Class exercises, including ones on characterization and aquifer remediation, will be used to reinforce concepts presented in the lectures.

Saltwater Intrusion Mitigation and Brackish Groundwater Development: An Overview (#304) May 2-3 • Navarro Room Presenters: Daniel Gomes, Robert Maliva, Ph.D., and Weixing Guo

This intensive two-day course consists of presentations, case studies, and lab exercises using Visual MODFLOW to introduce you to modeling environments, and the main steps involved, for developing brackish groundwater wells and reverse osmosis injection wells, which may play pivotal roles in helping to fulfill increasing demands for drinking water supplies.

The use of saltwater and brackish groundwater for drinking water purposes is becoming more common in the United States and abroad due to increasing overuse of fresh groundwater and induction of saltwater intrusion in coastal areas. In fact, the Texas Water Development Board, in its latest 50-year planning effort, lists brackish groundwater supplies as a key new resource to tackle the growing disconnect between supplies and demand.

Yet, there are still many difficulties in developing such a resource, including ensuring its long-term sustainability and potentially escalating costs with deteriorating water quality over time. Injection of RO concentrate in the subsurface also presents geochemical and well construction challenges.

8:00–8:20 a.m. Effects of Water Conservation on Wastewater Treatment Costs, City of Woodland, California Case Study Matthew Zucca, PE, Erler & Kalinowski Inc., and Dan Rich, PE, NEXGEN Utility Management

8:20–8:40 a.m. Energy Efficiency for Municipal Groundwater Systems Justin Rundle, PE, CEM, CCM, LEED-AP, Honeywell

Beyond the Phase II — Shifting from Investigation to Risk Management 8:00–9:00 a.m. Regency West 5 Moderator: Robert Appelt, PG, CAPM, (TX), ENERCON Once groundwater impacts are identified at a property, a strategy for the site must be developed for moving from problem identification and reporting to one of managing the problems over the long term. A variety of techniques exist for addressing identified problems — active or passive remediation, property restrictions, and risk-based approaches among others. At many sites, a combination of techniques may be needed to successfully manage impacts, with no one-size-fits-all approach. The various techniques require expertise in different subject areas, with opinions coming from experts in a variety of backgrounds and training. There are also a variety of regula-tory and institutional programs that may have authority over the problem, potentially further complicating the issue. This session looks at how the costs and benefits of different remediation and closure approaches are evaluated, strategies for implementation of the different approaches, and the long-term management of the options identified.

Groundwater Dewatering and Control in Sensitive Environments 8:40–10:00 a.m. Regency East 1 Moderator: Bill Fernandez, PE, CDM Smith Construction dewatering or water control are common terms used to describe removal or draining groundwater or surface water from a riverbed, construction site, caisson, or mine shaft by pumping or evaporation. This frequently involves the use of submersible dewatering pumps, centrifugal pumps, sump pumps, or application of vacuum to well points. When a dewatering site is located adjacent to environmen-tally or structurally sensitive features such as wetlands, surface water bodies, contaminated sites, or earthen dams, special considerations must be made in the design of a successful dewatering scheme. In addition, the long-term dewatering needs of such a site may be different given its proximity to the sensitive feature. This session showcases the innovative approaches practitioners have used to address groundwater dewatering near sensitive areas and lessons learned from successful applications.

Challenges in Characterizing and Modeling Karst Aquifer Systems 2:10–3:50 p.m. Regency West 6 Moderator: James R. Winterle, Edwards Aquifer Authority Karst aquifer systems are recognized as some of the most difficult to characterize and model. The multi-porosity structure of interacting matrix, fractures, dissolution features, and layer interfaces and the difficulty in determining the presence and locations of major conduits complicates the modeling of temporal response to recharge and pumping. The variable influence of geologic structure and faults — sometimes acting as conduits, sometimes acting as barriers, sometimes having no effect at all — further complicates model development. Yet, as water supplies become increas-ingly scarce, resource managers are increasingly relying on groundwater models to assess sustainable yields and to manage spring flows to support critical habitats and surface flows. This session features presentations that illustrate examples of effective aquifer characterization, conceptual model development, computational methods, and approaches for dealing with uncertainties in resource management decisions.

Ethics for Groundwater and Engineering Professionals 2:10-3:10 p.m. Regency East 2 Moderator: Jill Hernandez, Ph.D., University of Texas at San Antonio Professionals are challenged daily on how to meet the contractual obligations to clients while balancing regulatory, legal, and societal issues. The question of unethical behavior can easily surface in today’s litigious society. This workshop will provide insight into how the consummate professional can address these concerns in ways reflecting positively on the groundwater and engineering professions. This workshop will meet the one hour annual ethics training requirement specified by many societies and licensing bodies.

Hydrogeologic Characterization and Environmental Issues at Mining Facilities 2:10–3:50 p.m. Regency West 5 Moderators: Gaston Leone and Tim Cox, ARCADIS US Inc. Mining facilities pose distinct challenges when characterizing hydrogeo-logic settings to assess potential impacts during project development and permitting, start-up, during operations (e.g., mine dewatering, slope stability support), and after closure when groundwater remediation may be required. Mining facilities are typically associated with complex hydrogeo-logic settings and extreme environments. Mining projects typically involve consideration of fracture flow, regional-scale aquifers with local-scale dependencies, open pits, underground workings, groundwater-surface water interactions, waste rock dumps, tailings facilities, and development of pit lakes. These challenges provide opportunities for creative problem solving and innovation. This session provides a forum to discuss best practices, innovations, and issues in characterizing the hydrogeology and managing environmental issues at mining facilities.

Challenges in Characterizing and Modeling Karst Aquifer Systems (cont.) 4:20–5:40 p.m. Regency West 6 Moderator: James R. Winterle, Edwards Aquifer Authority Karst aquifer systems are recognized as some of the most difficult to characterize and model. The multi-porosity structure of interacting matrix, fractures, dissolution features, and layer interfaces and the difficulty in determining the presence and locations of major conduits complicates the modeling of temporal response to recharge and pumping. The variable influence of geologic structure and faults — sometimes acting as conduits, sometimes acting as barriers, sometimes having no effect at all — further complicates model development. Yet, as water supplies become increas-ingly scarce, resource managers are increasingly relying on groundwater models to assess sustainable yields and to manage spring flows to support critical habitats and surface flows. This session features presentations that illustrate examples of effective aquifer characterization, conceptual model development, computational methods, and approaches for dealing with uncertainties in resource management decisions.

Innovative Approaches for Investigating and Managing Karst Groundwater Resources 5:00–5:40 p.m. Regency East 1 Moderator: Barbara J. Mahler, U.S. Geological Survey Karst aquifers represent a vital water resource on a global scale, providing drinking water for an estimated 40% of the world’s population and critical habitat for numerous endemic species. Because of their rapid response to recharge, karst aquifers provide a continually renewable groundwater resource; they supply water for many urbanizing areas, but are highly vulnerable to contamination. Because of the unique hydrogeologic characteristics of karst systems, the development and application of innovative tools and interpretive methods is required to understand flow and transport in these aquifers, and creative approaches are required for their management. This session brings together hydrologists and managers who have developed new tools for investigating karst processes or innovative approaches for sustainable management of karst water resources.

McEllhiney Lecture Series in Water Well Technology: Keeping the Pump Primed: Aquifer Sustainability 10:50 a.m.–12:00 p.m. Regency East 2/3 Presenter: John Jansen, Ph.D., PG, Cardno ENTRIX No one can control, manage, or sustain what is not measured, so monitor-ing is the first step needed to ensure success. In terms of groundwater, monitoring can identify aquifers being used in an unsustainable manner and that information can then be used to find remedies to sustain the systems, as well as the industries and businesses that rely on them. One example of this, which will be discussed in this lecture, is the deep sandstone aquifer of northern Illinois and southeastern Wisconsin, where decades of overpumping have created one of the largest cones of depression in the world. Both states have conducted detailed studies of the aquifer and have begun regional planning to control the human and environmental impacts. (The McEllhiney Lecture Series is made possible by a grant from Franklin Electric.)

Remote (and Not So Remote) Ways of Estimating Groundwater Use in Agriculture 2:35–3:15 p.m. Regency East 3 Moderators: Robert E. Mace, Ph.D., PG, and Cameron G. Turner, Texas Water Development Board According to the U.S. Geological Survey – Estimated Use of Water in the United States in 2005 – there are 60 million irrigated acres across the nation using 144 million acre-feet of freshwater annually. Irrigation from groundwater accounts for 42 percent of this total, or 60 million acre-feet per year. This represents the largest consumptive use of groundwater: 67 percent of fresh groundwater withdrawals nationwide are for irrigation purposes. This illustrates the importance of accurate estimates of irrigation water use, and the need for adoption of best available science, technologies, and information sharing. Presentations will cover a broad spectrum of topics including remote sensing, evapotranspiration calculations, and collaborative efforts involved with a ground-up approach and offer a perspective on the various technologies and methods available to estimate irrigation water use and groundwater withdrawals for irrigation purposes.

This session covers all the components of data management and display for groundwater projects.

GHP System Engineering—Stimulating the “Engine” in Engineering 3:50–5:20 p.m. Regency Ballroom East 1 Presenter: John Pitz, CPI, NL Pitz Inc. Applying recognized engineering principles to outside the box thinking will result in better GHP system performance. Controlling the design and construction of the borehole impact heat transfer. The loop well field is designed based upon the yearly total of heating and cooling, not thermal conductivity. How efficiently equipment transfers the heat to the circulating water does not alter the loop well field. If a gain in efficiency is based upon a higher operating circulating water temperature, then the loop well field should be increased or baseline temperature water added to the GHP system (engineering). The “engine” is the mind of the engineer and groundwater professionals should engage in educating the engineering community, as well as themselves, on how to positively impact GHP system performance to ensure a robust industry and satis-fied consumers.

Hidrogeologia Moderna, Retos y Aplicaciones (Modern Hydrogeology-Challenges and Applications) 3:50–5:20 p.m. Regency Ballroom West 5 Presenter: Paul A. Hsieh, U.S. Geological Survey Following unsuccessful attempts during May and June 2010 to contain the Deepwater Horizon oil spill by methods such as the containment dome and top kill, and with the relief well not expected to be completed until September, plans were drawn up to install a capping stack on top of the Macondo well to shut the flow of oil. Such a shut-in was not without risks. During shut-in, the rising pressure in the well could force oil to leak out of the damaged casing into the surrounding formation, initiating a hydraulic fracture that could breach the seafloor. This would result in a renewed and uncontrolled flow of oil into the Gulf of Mexico —a catastrophic development. This talk will present some of the scientific analyses and behind-the-scene events that led to ending the Deepwater Horizon oil spill.

Eliminating or Exploiting Environmental Fluctuations to Improve Hydraulic Characterization8:00–9:40 a.m. Regency West 6 Moderators: Keith J. Halford, Ph.D., U.S. Geological Survey, and James J. Butler, Ph.D., University of Kansas Large-scale aquifer tests for groundwater development and contaminant transport projects can meaningfully reduce uncertainty of hydraulic-property estimates. Environmental fluctuations in groundwater levels from barometric changes, tidal forcing, or surface-water stage changes can hinder or enhance hydraulic characterization. Environmental fluctua-tions obscure drawdowns during pumping-aquifer tests and are best eliminated to expand the investigated volume. Hydraulic properties also can be estimated by interpreting the ubiquitous signals that environmental fluctuations provide.

Site Characterization and Management of Environmental Risks at Upstream Oil and Gas Fields 8:00.–10:00 a.m. Regency West 4 Moderators: David S. Lipson, Ph.D., PG, and Michael J. Gefell, PG, CPG, ARCADIS US Inc. Upstream oil and gas fields pose unique challenges to scientists and engineers tasked with characterizing and managing environmental risks. These challenges may include complex hydrogeologic settings, unknown or often incomplete knowledge regarding chemical releases, and com-plex mixtures of chemicals such as petroleum hydrocarbons, salts, and naturally occurring radioactive materials. Furthermore, upstream oil and gas fields offer unique health, safety, and logistical challenges due to their large size and remoteness, which can pose significant site access challenges. Lastly, environmental regulation of upstream oil and gas fields in the U.S. has been left largely to the states, resulting in different environmental policies in different states. However, these challenges also provide opportunities for creative problem solving and innovation.

Characterizing Biology with Water Quality in Karst: What Can It Tell Us About Aquifer Health 9:40–10:00 a.m. Regency West 5 Moderator: Marcus Gary, Ph.D., PG, Edwards Aquifer Authority Karst aquifer systems are frequently host to diverse biological habitats that are inherently unique to the Earth’s subsurface. These ecosystems are directly linked to the hydrogeology through water that moves though the aquifer, and are subject to changes in water quality that may affect the health of a species or group of species. In many cases, karst aquifer ecosystems can be indicators of emerging water quality concerns that have yet to directly affect anthropogenic uses of the groundwater resource.

2013 Birdsall-Dreiss Lecture: How Do Porous Terrestrial Surfaces Control Evaporation into the Atmosphere? 10:15–11:15 a.m. Regency East 2/3 Presenter: Dani Or, Ph.D., Institute of Terrestrial Ecosystems Globally, evaporation consumes about 25 percent of solar energy input and is a key hydrologic driver with approximately 60 percent of terrestrial pre-cipitation returning to the atmosphere via evapotranspiration. Quantifying evaporation is important for assessing changes in hydrologic reservoirs and surface energy balance, as well as other applications. However, evaporation dynamics from porous media is significantly different than from free water surfaces. Implications of the findings for estimates of evaporative losses used in hydrological and climate models will be discussed during this lecture.
