Hydrogeology

Overview

Faculty and students in the UW-Madison Hydrogeology research group are engaged in investigation into both the applied and purely scientific aspects of hydrogeology. Research interests within the group are diverse and fall under the general categories of groundwater flow, solute transport, groundwater remediation and numerical modeling. Most research projects combine aspects of several of these categories.

Collaboration with UW researchers in departments other than Geoscience (Civil & Environmental Engineering, for example) is common. There is also significant collaboration between the UW Hydrogeology group and researchers at the Wisconsin Geological and Natural History Survey (WGNHS) and the Middleton office of the US Geological Survey (USGS-Middleton), both of which are located in the Madison metro area.

UW-Madison has long been recognized as one of the premier hydrogeology research universities in the nation. It was at UW-Madison that some of the foundations of the field of hydrogeology were established in the late-19th and early-20th century. This tradition of excellence continues today: in the most recent ranking of geology graduate programs by US News, UW-Madison is tied for seventh. Alumni of the program have gone on to highly successful careers in the academic, government and private sectors.

The Hydrogeology program leads to M.S. and Ph.D. degrees in Geology & Geophysics. Click here to find out how to apply to the UW-Madison Hydrogeology research group.

Faculty

Michael A. Cardiff, Associate Professor

I am interested in understanding aquifer heterogeneity through hydrologic and geophysical methods, and in environmental decision making under uncertainty.

Herbert F. Wang, Professor

I am interested in poroelastic behavior of rocks and geodynamical modeling because they link observations to geologic processes.

Christopher Zahasky, Assistant Professor

My research focuses on using imaging technologies such as X-ray computed tomography (X-ray CT) and positron emission tomography (PET) to make experimental observations of fluid transport in geologic porous and fractured media. Combined with numerical and analytical methods, it possible to better understand fundamental transport processes that control everything from contaminate transport in aquifers to water and steam migration in geothermal reservoirs. Check out more details on the Experimental Hydrogeology Lab Group Website.

Aquifer Storage and Recovery (ASR) is a method for the underground storage of water that is used in many parts of the world.  In the late 1990’s and early 2000’s, ASR using treated surface water was investigated as an option to enhance municipal water supply capacity in Green Bay, WI.  ASR was ultimately determined to be infeasible at the site due to high levels of arsenic in the recovered water.  My thesis focused on incorporating aquifer heterogeneity into a groundwater flow model for the ASR site and modeling the chemical changes associated with arsenic release and transport during ASR test cycles.  Examination of a core from the site allowed for the identification of preferential flow paths within the Tunnel City Group, one of the units penetrated by the ASR well.  Oxidation of pyrite is proposed as the source of arsenic during ASR, and these preferential flow zones often coincide with zones of pyrite mineralization.

My graduate research has focused on groundwater flow in glacial deposits.  Currently, I am researching the nature of preferential flow paths in a heterogeneous glacially-deposited aquitard and how they affect groundwater flow and transport.  This is significant as studies that have investigated preferential flow and related topics in aquitards have mainly focused on flow through aquitards, not flow within the aquitard. A representative site has been selected in Outagamie County, Wisconsin where a bedrock valley has been filled with a thick sequence of sediment, dominated by lake sediment with some glacial till and sand lenses of uncertain deposition.  This sediment appears to form an extensive aquitard, occasionally surrounding sand lenses of unknown extent and continuity.

I use multiple-point geostatistics to create hydrostratigraphic models, based on well logs, slug tests, electrical resistivity imaging, and drilling.  These models will then be imported into groundwater flow and transport models.  Finally, statistics of connectivity, particle tracking, and other analyses will be performed on both the hydrostratigraphic and groundwater flow models and used to determine if certain connectivity statistics can be used to predict groundwater flow and transport through preferential flow paths.

My graduate research focuses on how urban sewer effluent is able to rapidly migrate into deep, confined aquifers and contaminat
e water supply wells.  Preferential flow pathways may be related to 1) flow though fractures and bedding planes, 2) leaky confining units combined with steep hydraulic gradients due to pumping, or 3) poorly constructed municipal well casings.  Field work in Madison, WI involves sampling sewer effluent and groundwater for human enteric viruses and geochemical constituents; measuring water level fluctuations in response to municipal well pumping to determine poroelastic effects; and studies of outcrop, logs, and core to identify fractures.

My project involved investigating sources of nutrients to a lake in Door County undergoing eutrophication. As the lake is connected to the groundwater system, this included building a groundwater flow model to delineate the zone of groundwater contribution to the lake.

Installing minipiezometers from a boat at Dunes Lake.

Along with chemical analyses of water samples from a number of locations in the watershed (including a municipal wastewater settling pond which discharged directly upstream of the lake), I was able to estimate the relative contribution of various activities to the nitrogen and phosphorus budgets for the lake.

It’s a beautiful place (even if the logistics of working on and around an untamed fen can be a bit frustrating) where cranberries and carnivorous pitcher plants can be found 20 yards from pH 8 lake water full of huge snail shells. It’s also the only place I’ve ever been physically threatened by a Sandhill crane.

Subsurface heterogeneity in hydraulic properties and processes is a fundamental challenge in hydrogeology. My M.S. research with Professor Bahr focused on the use of distributed fiber-optic temperature sensing (DTS), which allows for the rapid profiling of temperature, to characterize aquifer heterogeneity and flow in multi-aquifer wells. This included experiments at the Oak Creek, WI Aquifer Storage and Recovery (ASR) site, where temperature was continuously profiled in an 1800 ft. deep, 20″ diameter monitoring well, under ambient conditions and with an identical ASR well pumping from 180 ft. away. The DTS results, interpreted in combination with numerical modeling and extensive ASR cycle data, recorded complex, transient vertical flows in the monitoring well induced by pumping in the ASR well. Single-well thermal tracer tests, in which the injection of heated water was monitored by DTS, were also conducted in two multi-aquifer wells near Madison.

The DTS data revealed intervals of intergranular and fracture-dominated inflow, including diverging flow emanating from a cluster of bedding-plane fractures in the Wonewoc Sandstone (see image from DN-1440). The results of these experiments suggest that DTS holds great potential as an efficient and highly detailed down-hole characterization method.

Other projects I enjoyed at UW included an interdisciplinary practicum for my Water Resources Management degree, which investigated the environmental, social, institutional and land-tenure issues affecting the restoration of a former Cypress-Tupelo swamp in New Orleans, and a DTS experiment measuring ventilation 4100′ below ground in the Homestake Mine.

I am working with the USGS and WGNHS in the Park Falls District of the Chequamegon-Nicolet National Forest to determine how climate change will affect surface water and groundwater resources in northern Wisconsin. We are using a groundwater flow model (GFLOW) to determine how much total flow in certain streams and lakes in the forest is dependent on groundwater discharge.  We will verify the modeled values of groundwater discharge with a variety of techniques, including field measurements, stable isotope mass balances, geochemical mass balances and baseflow recession.

Once we determine and verify groundwater discharges, we will use precipitation values predicted by down-scaled climate models in the groundwater flow model.  How those surface water bodies react to the new precipitation values will give us some insight into how susceptible streams and lakes are to climate change, and how to best manage those surface water bodies.  Our hypothesis is that as groundwater dependency increases in a surface water body, lake level and stream flow variability decreases, since groundwater will offer a long term source of water that is comparatively unaffected by short term variability in precipitation.

My research interests deal mostly with the poroelastic deformation of rock masses. A large component of this research is the characterization of rock mass properties based upon baseline tilt measurements. Hydrostatic level system (HLS) arrays measure the relative displacement of two points along a rock surface with precision up to 10-8 radians. Forces generating displacement include Earth tides, large distributed surface loads (e.g. floods), and anthropogenic activity.  I am currently processing and analyzing data from three HLS arrays: the DUSEL site (former Homestake gold mine) in Lead, SD, the LaFarge limestone mine in North Aurora, IL, and the MINOS facility at Fermilab in Batavia, IL.

Another active interest is coupled pore fluid diffusion and stress analysis. More specifically, I am interested in using finite element modeling to demonstrate the effect of subsurface heterogeneity on reverse groundwater fluctuations during aquifer pumping.
