Introduction
Hydrogeologist, Professional Geologist, and PhD student at the University of Illinois. I use groundwater flow models (MODFLOW) and isotopes to understand structural controls (faults) on groundwater flow and geochemistry, research surface water/groundwater interactions, and conduct long-term water supply planning. I occasionally participate in Grand Canyon geomorphic research.

As shallow aquifers become depleted or contaminated worldwide, use of deep aquifers will likely increase to meet growing water demands despite expensive drilling costs and well maintenance, and limited recharge to many of these deep systems. We discuss depletion of the Cambrian‐Ordovician sandstone aquifer, a deep bedrock aquifer that has been a ma...
Faults can act as flow barriers or conduits to groundwater flow by introducing heterogeneity in permeability. We examine the hydrogeology of the Sandwich Fault Zone, a 137 km long zone of high‐ angle faults in northern Illinois, using a large‐scale historic aquifer test. The fault zone is poorly understood at depth due to the majority of the faults...
Deep basin aquifers are increasingly used in water‐stressed areas, though their potential for sustainable development is inhibited by overlying aquitards and limited recharge rates. Long open interval wells (LOIWs) —wells uncased through multiple hydrostratigraphic units— are present in many confined aquifer systems and can be an important mechanis...
Sandbars along the Colorado River in Grand Canyon National Park, USA, are an important recreational resource used as campsites by over 25,000 river runners and hikers annually. The number and size of campsites decreased following the completion of Glen Canyon Dam in 1963 due to reductions of sediment that replenish sandbars and increases in vegetat...
Sandbars along the Colorado River are used as campsites by river runners and hikers and are an important recreational resource within Grand Canyon National Park, Arizona. Regulation of the flow of river water through Glen Canyon Dam has reduced the amount of sediment available to be deposited as sandbars, has reduced the magnitude and frequency of...
This report examines the impacts of current and future demands on water supplies for the
Kankakee Watershed Water Supply Planning Subregion (WSPR) in northeastern Illinois, an area comprising most of Kankakee and Iroquois Counties and portions of Ford, Will, Vermilion, and Grundy Counties that intersects the Kankakee River watershed boundary.
Groundwater withdrawals from the St. Peter and Ironton-Galesville Sandstones in northeastern Illinois have resulted in head declines over 300m since pre-development. Municipal and industrial demands continue to stress the aquifer, creating a large cone of depression centered in Will County, IL. The Sandwich Fault Zone, a high-angle fault system tha...
Sandbars along the Colorado River in Grand Canyon National Park, USA are an important recreational resource used as campsites by over 25,000 river runners and hikers annually. The number and size of campsites decreased following the completion of Glen Canyon Dam in 1963 caused by reductions of sediment supply, vegetation encroachment, and streamflo...
Over 1,300 communities throughout Illinois rely on different sources of water for municipal, industrial, and residential use. Sources of water include Lake Michigan, inland surface waters such as rivers and reservoirs, groundwater, or a combination of sources. Communities may also purchase water from other communities or from public water distribut...
The aqueous geochemistry of the St. Peter Sandstone, a major aquifer in the Illinois Basin, an intracratonic sedimentary basin, is extremely complex. There are multiple sources of water, including in situ remnant brines, leakage from overlying and underlying units, and recharge during both the Pleistocene and Holocene Epochs. In our study region, r...
Groundwater withdrawals from the St. Peter and Ironton-Galesville Sandstones in northeastern Illinois have resulted in head declines up to 900 feet since pre-development. Municipal and industrial demands continue to stress the aquifer, creating a large cone of depression centered in Will County, IL. The Sandwich Fault Zone, a high-angle fault syste...
More than 1,300 communities in Illinois rely on different sources of water for municipal, industrial, and residential use. Sources of water throughout the state include Lake Michigan, inland surface waters such as rivers and reservoirs, groundwater, or a combination of sources. Communities may also purchase water from other communities or from publ...
The Illinois State Water Survey (ISWS) and the U.S. Geological Survey (USGS) recently completed drilling of a new deep sandstone monitoring well in Kendall County, IL. The 1,180 feet deep borehole has two nested wells, one which is open to the St. Peter Sandstone and one that is open to the deeper Ironton-Galesville Sandstone. Groundwater withdrawa...
The St. Peter and Ironton-Galesville sandstones, the principle stratigraphic units that comprise the Cambrian-Ordovician aquifers in Illinois, are a primary source of water for northern Illinois and southern Wisconsin, especially where uncontaminated shallow groundwater or surface water is not available. By 1980, heads in these sandstone units had...
River rafting trips and hikers use sandbars along the Colorado River in Marble and Grand Canyons as campsites. The U.S. Geological Survey evaluated the effects of Glen Canyon Dam operations on campsite areas on sandbars along the Colorado River in Grand Canyon National Park. Campsite area was measured annually from 1998 to 2012 at 37 study sites be...
