1. BUILDING AN INFORMATION FRAMEWORK FOR
WATER SUPPLY PLANNING AND ECONOMIC DEVELOPMENT:
3-D GEOLOGIC MAPPING IN NORTHEASTERN ILLINOIS
Much of our drinking water, a significant amount of material for road building, and most natural lakes in
Illinois have one thing in common: they are a legacy of the Ice Age—glaciers created the geologic materi-
als that contain groundwater, are used in concrete, and form the containers that enclose lakes. Knowing
the distribution and characteristics of these materials is essential for water supply planning, economic
development, and sustainability of our recreational resources. A geologic map achieves that goal, and
three-dimensional (3-D) geologic maps can depict these materials several hundred feet under the ground.
Geologic maps provide a context for every decision that relies on information about the earth under our
homes, roads, and cities. These maps help us understand the availability of groundwater resources; help
avoid building in areas that are susceptible to natural hazards, such as landslides; and help those entrusted
with protecting our health and safety to make decisions. A Geologic Mapping Advisory Committee,
composed of experts from private industry; academia; and local, state, and federal governments, provides
advice on immediate and long-term societal trends that guide geologic mapping priorities.

3-D geologic maps provide critical information for informed decision making related to all
of our natural resource needs and for protecting our health and safety from natural and
man-made hazards. Digital 3-D geologic map layers can be deployed in a county GIS for
effective use with other digital information, such as land parcel, land-use zoning, and park
and natural area boundary maps. This information has supported a number of water-sup-
ply decisions in Lake County, including planning for additional water withdrawal from Lake
Michigan. For planning purposes, dramatic changes in geology over short distances has weak-
ened confidence in long-term reliance on groundwater for western Lake County communities.
Information gleaned from 3-D geologic mapping explains why some communities have been
unable to find suitable aquifer material in areas near existing groundwater production wells.
Because each additional allocation of Lake Michigan for some Illinois communities affects the
potential future use of that resource for other communities, geologic maps that show aquifers
are essential to the long-term sustainability of both our groundwater and surface water.
Geologic mapping requires examination and geologic interpretation of historical records and
maps containing facts and observations about surface and subsurface geology. Additional
information is acquired through a number of exploration methods, including drilling. These
data are combined in a geographic information system (GIS) to form a robust 3-D database.
State-of-the-art software applications and advanced database management techniques enable
3-D representation and visualization of subsurface information. 3-D visualization provides the
capability to create enhanced 3-D geologic map products. Interaction with users of geologic
information provides opportunities to customize map products for application-specific needs.

3. HYDROLOGICAL FUNCTIONING AND HISTORY
OF NELSON LAKE: PROTECTING THE “JEWEL OF
KANE COUNTY” FROM URBAN ENCROACHMENT
Nelson Lake, a shallow, spring-fed lake with a wide buffering fen, is home to a nesting group of white peli-
cans, as well as rare calciphyllic orchids and other flora. Urban development and its potential impacts on
Nelson Lake were investigated through study of the hydrological functioning of the lake: its water residence
time, water chemistry, and the long-view history of lake water quality and the surrounding vegetation. Digital
modeling of the geological data acquired for the study showed a large teardrop-shaped capture zone, which
was immediately purchased or rezoned by the county. The short residence time of Nelson Lake water (less
than 3 months) and surrounding geology and topography means that it is constantly being recharged by shal-
low groundwater. Today, the capture zone of this shallow aquifer is largely overlain by soccer fields and not
strip malls and subdivisions, thereby protecting the unique and fragile aquatic and wetland ecosystems.
The long view of the functioning of Nelson Lake warns us that drought leads to landscape instability, the
erosion of the surrounding morainal landscape, and rapid infilling of what is already a shallow lake.

The most profound result of the study was its immediate use by the County Forest Preserves
to purchase and rezone property determined to lie within the capture zone delimited by our
study. The properties, which were slated for residential and small business use, are now a
large sports park maintained by the county. The results of the borings, geophysical logs,
electric earth resistivity surveys, and other analyses were used to help construct a three-
dimensional model of the glacial sediment used to model groundwater flow in the drift (Dey
et al. 2007). The paleoecological studies of the lake sediment core revealed that droughty
periods led to rapid infilling of the lake from about 8,200 to 6,700 years ago (Nelson et al.
2003). Instead of being hydrologically open, Nelson Lake during that time was internally
drained, and its microflora were sensitive to inputs of limiting nutrients.
A holistic investigation of the subsurface geology revealed that Nelson Lake, a glacial kettle,
is nestled in thick deposits of sand and gravel that rapidly thin away from the lake. The
research included sampling eight sediment cores to bedrock and a continuous sounding
of the electrical properties of the sediment immediately surrounding the lake. By mapping
the thickness and extent of the sand and gravel, measuring water levels in the sand and
gravel aquifer from an array of monitoring wells, and conducting sensitivity analyses of the
hydrological and geographical variables in the analysis, we mapped the capture zone of the
shallow aquifer. The fossil record of pollen, charcoal, plant macrofossils, and ostracodes
(archived in a 50-foot-long sediment core from the center of Nelson Lake) revealed a rich
history of biotic response to climate change, including late Pleistocene deglaciation, and
climatic conditions over the past 10,000 years, including periods of severe drought.

5. WETLANDS PROGRAM
Wetlands provide us with a wide variety of benefits, including wildlife habitat, outdoor recreation,
groundwater recharge, floodwater storage, and water-quality improvement. The loss of 90% of Illinois
presettlement wetlands with attendant losses of these benefits prompted federal, state, and local laws
to protect wetlands and the services they provide. As a result, activities that affect many (but not all)
wetlands are subject to regulation, and governmental agencies, industry, and NGOs are routinely faced
with wetland-related decisions to meet resource conservation policies, regulatory requirements, or both.
These decisions involve issues including protection of sensitive, high-quality wetland habitats, wetland
restoration or creation, and construction of artificial wetlands to treat runoff. These groups depend on
information based on impartial collection and unbiased interpretation of data that accurately describe the
physical, hydrological, and biological characteristics of wetlands.

In a large, recent project providing assistance to the Illinois Tollway Authority, monitor-
ing and analysis of flow volume, water chemistry, and sediment in treatment wetlands
(bioswales) constructed to improve the quality of roadway runoff showed that most of
the bioswale sites are equally as or more effective than other best management practices,
depending on the design parameters and other site characteristics. This information will be
used to guide the design and implementation of bioswales in future road construction proj-
ects. Other notable results include identification of the geochemical conditions that sustain
populations of the federally endangered dragonflies, recommendations for restoration of the
large and unique ecosystem at Illinois Beach State Park, assistance to the Illinois Department
of Transportation (IDOT) with wetland restoration and creation for its wetland mitigation
program, evaluation of the influence of floods on the quality of plant communities at IDOT
wetland restoration sites, and delineation of groundwater protection areas for high-quality
habitats at Illinois Nature Preserves.

7. A NONCONVENTIONAL CO2
-ENHANCED OIL RECOVERY
TARGET IN THE ILLINOIS BASIN: OIL RESERVOIRS OF
THE THICK CYPRESS SANDSTONE
Illinois contains economically significant energy resources in the form of natural gas, oil, and coal.
However, extraction of oil from some reservoirs (typically several thousand feet deep) through typical
recovery methods is hampered by the geologic complexities of the oil-bearing reservoir and adjacent
rocks. The oil in the reservoir rock is often accompanied by the occurrence of extremely salty water (brine).
During oil production, brine can enter the well instead of oil. Typically, these nonconventional oil-rich
zones are bypassed because of the expense of producing the oil resource and removing the brine, which
is an unwanted by-product that creates additional cost. However, innovative oil extraction methods and
technologies show great potential for recovering bypassed oil from nonconventional oil rereservoirs and
mitigating the impact of human-induced climate change. With the current impetus to reduce greenhouse
gas emissions, the carbon dioxide (CO2
) from anthropogenic or natural sources can be used to enhance oil
recovery in these nonconventional reservoirs while storing or sequestering it deep in the ground.
This study focuses on developing methods to increase CO2
enhanced oil recovery (EOR) in nonconven-
tional oil reservoirs and demonstrating economic incentives for CO2
storage and CO2
use to facilitate oil
production in the Cypress Sandstone of Illinois. The findings will be extrapolated to a regional resource
assessment and could potentially be used to aid in the development of oil resources that actually result
in removing more carbon from the atmospheric part of the carbon cycle than is created by the burning of
carbon removed from the ground.

Application of these techniques will provide data that can be used to create guidelines and
recommendations for CO2
-EOR development strategies (e.g., well patterns, spacing, and
orientations as well as CO2
injection profiles) of the thick Cypress Sandstone (and similar
formations) that provide operators an economic incentive to store CO2
. Lessons learned from
this research may be extrapolated to other known and as yet undiscovered nonconventional
oil reservoirs in similar geologic formations, both within Illinois and at other locations in
the United States. Most important, the research could demonstrate that the use of CO2
to
enhance oil recovery also could potentially be used to store carbon otherwise released to the
atmosphere, thereby creating net carbon-negative oil projects.
Reservoir characterization, geologic mapping, three-dimensional modeling, and simula-
tion of oil and brine flow in the thick Cypress Sandstone and adjacent rocks will be used to
develop methods for improved oil recovery and storage efficiency through CO2
injection.
Results from a detailed oil field study will be scaled up and coupled with regional geologic
mapping to estimate the size of the potential nonconventional CO2
-EOR and storage resource
in the Illinois Basin. Economic evaluations will be completed so that the relatively high
storage component anticipated from these formations can be understood in terms of the
magnitude of the CO2
-EOR and storage.

9. ILLINOIS BASIN – DECATUR PROJECT
Carbon capture and storage (CCS) from ethanol production represents a significant opportunity to miti-
gate climate change because of the low cost of capture and purity of the carbon dioxide (CO2
) produced.
The Illinois Basin – Decatur Project (IBDP) is an integrated CCS project being carried out in Decatur, Illinois,
by the Illinois State Geological Survey. The IBDP is a full-cycle CCS project—from site characterization to
closure—with the goal of injecting one million tonnes of anthropogenic CO2
captured from biofuel produc-
tion into a deep saline rock formation, the Mt. Simon Sandstone. The IBDP has successfully completed
three years of CO2
injection, with cumulative injection of one million tonnes as of November 2014. The IBDP
now moves into a three-year post-injection monitoring period.

• In total, 999,215 tonnes have been stored over three years.
• Three years of pre-injection and three years of injection monitoring have been undertaken.
• All parameters show full containment of CO2 in the deep subsurface.
At the end of the project, we will understand:
• carbon storage infrastructure development and implementation.
• thresholds for geophysical (3-D vertical seismic profile and 2-D line) plume detection
based on rock type, depth, perforated interval, and reservoir properties.
• the pressure front distribution and timing of CO2 movement.
• the distribution of microseismic events in 3-D space around the injection well and how
clusters of events develop.
The information gained from this project is being used around the world to mitigate the
impact of greenhouse gas emissions on climate change.
The IBDP, led by the Illinois State Geological Survey in partnership with Archer Daniels Midland
Company (ADM) and Schlumberger Carbon Services, is demonstrating the geological stor-
age of 1 million tonnes of CO2
more than 7,000 feet beneath the surface. The project began
in 2008 and has created the entire infrastructure needed for carbon storage, including deep
injection and monitoring wells, a compression/dehydration facility, a pipeline, and intensive
shallow and deep monitoring systems. The IBDP captured CO2
from ethanol production
at ADM for a period of three years. A three-year period of post-injection monitoring and
research is underway to understand the reservoir response to the cessation of CO2
injection.

11. KARST INVESTIGATIONS IN NORTHWESTERN
AND SOUTHWESTERN ILLINOIS
About 10 percent of Illinois contains karst terrain. Karst is simply defined as an area underlain by fractured
bedrock whose fractures are enlarged by dissolution of the rock. Limestone and dolomite are susceptible
to dissolution by rainwater and soil water. The larger the fracture apertures, the more likely that sediment
will fall into the fractures or crevices and create sinkholes. The fractures and crevices also provide porosity
and permeability of the bedrock. Under certain hydrologic conditions, the fractures and crevices may be
filled with water. Provided the water quality is suitable for drinking, the fractured rock becomes an aquifer.
However, because the crevices are so large (sometimes cave size), recharge and groundwater movement
are rapid and highly susceptible to surface-borne contamination. Consequently, karst terrain is a unique
environment that requires special care when building structures and infrastructure so as not to compro-
mise the water resources of the karst aquifer. Karst terrain is also susceptible to collapse, creating a safety
hazard. In addition, the caves in these areas provide a unique environment that records climate change,
changes in land use, and earthquakes. The work we are doing in the karst areas of Illinois focuses on
protection of water resources and on taking advantage of the natural records housed within its caves.
For more information, visit: www.isgs.illinois.edu

12. Characterize the degree and extent of karst terrain on local and state levels to determine the
susceptibility of associated karst aquifers to surface-borne contaminants in northwestern and
southwestern Illinois, and identify seismic history associated with the New Madrid and Wabash
Valley Seismic Zones in Illinois and adjacent states through the use of speleothems in caves.

A field trip through Jo Daviess County in northwestern Illinois was attended by more than 150
citizens and demonstrated community interest in understanding the ramifications of living
in karst terrain. Each was provided a field trip guidebook that included a detailed description
of the history, archaeology, biology, geology, and hydrology of the county. The guidebook
is now being used throughout the county as a primer on the natural history of northwestern
Illinois and the value of citizen participation in implementing groundwater protection strate-
gies. In southwestern Illinois, the techniques we developed for identifying seismic events by
using speleothems in caves are being applied to fill in gaps in the seismic history of the New
Madrid Seismic Zone and the Wabash Valley Seismic Zone. These records demonstrate that
ground-shaking (earthquake) activity has recurred during the last 200,000 to 300,000 years.
Water quality investigations in karst regions of the state are conducted through mapping
of karst features (e.g., sinkholes, large springs, crevices) by using aerial photography,
enhanced-resolution digital elevation data, and results of water chemistry. Groundwater
samples are obtained from private wells and springs and analyzed for chemical composition,
tritium, bacteria, pharmaceuticals, and personal care products to determine baseline condi-
tions. Review of land use can lead to likely sources of existing contamination. In addition, the
region’s seismic history, or record of ground shaking, has been discovered through examina-
tion of stalagmites from caves in southern Illinois and adjacent states. Our close relationship
with community leaders helps us identify local and regional issues. Citizen involvement and
community-supported outreach create an information network and ready assistance for the
protection of local resources.
