PROJECT TITLE
Kendall County Hydrogeologic Resource Assessment
PROBLEM
Kendall County, located in north-central Illinois, has experienced rapid population growth in recent years.
Water for the population of Kendall County is supplied exclusively by ground water froth residential- and
municipal-supply systems. Ground-water withdrawals have exceeded recharge in aquifers used for
residential supply in parts of northern lllinois, resulting in excessive drawdawn and water-supply
interruptions in residential-supply wells. These interruptions have necessitated lowering of pumps and, in
many cases, deepening of wells at substantial expense to the affected homeowners. Ground-water
withdrawals also have exceeded recharge in aquifers .used for municipal-supply in parts of northern lllinois,
which has necessitated switching to alternate water supplies (Lake Michigan and the Fox River) or drilling
additional wells. Continued population growth will increase the demand on the ground-water resources in
Kendall County, potentially resulting in an inability to meet water demands. Alternate sources of water
either are not legally accessible, as is the case with Lake Michigan, ar may require expensive pretreatment
and provide limited amounts of water, as would likely be the case with the Fox River. The first step in
ensuring the long-term sustainability of ground-water in Kendall County requires a comprehensive
assessment of the resource and the current and projected demands upon that resource. Based on the results
of this assessment additional investigative tasks might be performed, which could lead to the development
of a computer model of ground-water flow in the county that can be used to determine the effect of current
and projected future water use on the availability of ground water.
OBJECTIVES
The objective of this investigation is to determine the geologic, hydraulic, water-use and water-quality
conditions that affect the sustainability of water supply from the aquifers underlying Kendall County.
RELEVANCE AND BENEFITS
To provide an effective preliminary assessment of the ground-water resources in Kendall County, the U.S.
Geological Survey (USGS) will compile the readily available information on the geology, hydrology, water
quality, and water use in the aquifers used For water supply so that areas of potential water-supply problems
can be identified. The data are critical to community planners far broad-based planning and managing of
water-resources projects that consider drought warning and assessment, subsurface water storage, and the
effects of changing land use. The preliminary assessment will be published in a report and be made
available on the World Wide Web. This assessment will provide the foundation for additional gealagic and
hydraulic characterization of the aquifers, which may be used in the development of a computer model of
ground-water flow. A flow model, if developed, can be used to determine sustainable yields by aquifer and
identify the effects of population growth and climatic changes on water supplies.

additional demands on the limited water supplies
Water-supply needs in the county are et exclusively from ground water derived from glaci 1-drift aquifers
and bedrock aquifers open to the Alex drian-Maquoketa, Galena-Platteville, Cambrian-Or ovician aquifer
systems. Many homes rely on water f mresidential-supply wells from the glacial-drift, AI xandrian-
Maquoketa, Galena-Platteville, and th uppermost part of the Cambrian-Ordovician aquifer . Public water-
supply systems in the county also are pen to the glacial-drift aquifer, but most draw water om the deeper
parts of the Cambrian-Ordovician aqui er system.
Overutiliztion of ground-water resour sin residential wells has resulted in water-supply in rruptions in
the glacial-drift aquifer and the Alexa drian-Maquoketa and Galena-Platteville aquifers in p s of northern
Illinois (Kay and Krakse, 1996). Ove tiliztion of ground-water resources in the Cambrian- rdovician
aquifer system in much of northern Illi ois has forced several municipalities to switch from round water
to Lake Michigan or (in part) the Fox fiver for water supply. Continued population growth in Kendall
County and nearby areas increases the possibility of future interruptions in water supply. D ersion of
water from Lake Michigan to Kendall ounty is not permissible legally and the amount of ater that can
be diverted for water supply from the ox River would require pre-treatment to be potable a d it likely to
be insufficient to meet the entire Ovate needs of the county. It is essential, therefore, that th ground-water
resources of Kendall County be fully aracterized so that the long-term sustainability of th resource can
be determined and interruptions in Ova r supply can be avoided.
APPROACH
1. Previously published reports attaining to the soils, geology, hydrology, water qua ity, and water
use in the county and surroun ing areas will be reviewed. Pertinent data will be co piled,
analyzed, and interpreted. is data will include, but will not be limited to, reports on file with the
USGS, Kendall County Depa ment of Public Health (KCDPH), Illinois State Geol gical Survey
(ISGS), Illinois State Water rvey (ISWS), Illinois Environmental Protection Ag cy (IEPA),
and U.S. Environmental Prot ction Agency (USEPA).
2. Electronic versions of the logs for the public-supply wells and the residential-supply wells drilled
since 1980 in Kendall County and parts of the surrounding area are present in USGS databases.
Additional logs may be on file with the KCDI'H and the ISWS. These logs will be compiled,
analyzed, and interpreted. These logs include information on the location of the well, geologic
deposits penetrated during drilling, the geologic deposits supplying water to the well, the static
water level, and the specific capacity of the well. Well locations will be verified and combined
with topographic data to establish the approximate altitude of the land surface at the well.
3. Information collected by the operators of municipal-water supply systems, including well-
construction information, annual water withdrawals, results ofwater-quality sampling, and water-
level measurements will be compiled, analyzed, and interpreted. Receipt of information not on
file with the IEPA, such as water-level data, will be dependent on the cooperation of the system
operators.
4. Available hydraulic and water-quality information on the Fox River in Kendall Caunty will be
compiled. Flow data from the USGS gages at Montgomery and Dayton also will be compiled and
analyzed.
5. Information on file with the Northeast Illinois Planning Commission, the County, or local
municipalities regarding historic and current population patterns and land use in Kendall County
as well as projected trends in population and land use will be compiled, analyzed, and interpreted.
Receipt of this information will be dependent on the cooperation of the regional and local agencies
that have this information.
6. Analysis of the data collected during steps ]-3 will be combined to provide a geologic framework
for the county, a starting point for the hydraulic framework, a starting point far the factors that
affect ground-water quality, and an understanding of water use. This information will be used to
plot features of hydrogeologic importance in the county including the location and thickness of
sand-and-gravel deposits; the thickness of silt-and-clay deposits; the altitude of the bedrock
surface; the lithology of the geologic deposits beneath the county; the altitude of the top and
bottom of the aquifers used for water supply in the bedrock deposits; general spatial trends in
aquifer permeability; potential for aquifer recharge; areas where water quality has been degraded
by natural or anthropogenic compounds, and possibly the directions of ground-water flaw.
Information collected during step ~1 will be used to provide some indication of the viability of the
Fox River as an alternate water supply.
The information collected for his investigation will be used to estimate self-supplie residential
water use in the county, to pr ide a preliminary assessment of the hydrogeologic f ctors that
contribute to ground-water-qu lity degradation (if any), to identify aquifers which c rrently may
be overutili2ed (if any), to pro ide a preliminary assessment of the hydrogeologic a d water-use
factors that contribute to aqui r overutilization, to provide a preliminary assessme t of the
effects of population growth aquifer overutiliztion, and potentially to identify po sible viable
sources of alternate water sup ly. The results of this investigation can be used toe iciently focus

May 30, 2003
Mr. Terrance Burghard:
Through consensus at the May 7a' Mayors and Managers Meeting, the Kendall County Board and the majority of
municipalities in Kendall County agreed to partner on a Phase I U.S. Geological Survey groundwater study project
for Kendall County. At that time, the group also directed the steering committee to determine the division of local
cost for the project and that an agreement be developed with USGS to allow the Kendall County Soil and Water
:Conservation District (SWCD) to be the project leader and grantee.
The steering committee met at the Kendall County SWCD office on May 28`x. The total local cost for this three-
year Phase 1 Groundwater study is $42,964.00. The Kendall County Soil and Water Conservation District agreed to
sign the Joint Funding Agreement with the USGS and handle the local funds. 'T'he SWCD is asking the County and
each municipality to sign the enclosed resolution, formally committing to the project partnership. Also enclosed
with this letter, please find a contact sheet and the full proposal for this project.
The costs listed below are the total for each municipality aver the federal Fiscal Years of 2003, 2004, and 2005.
The Kendall County SWCD will be billed each fiscal year of the project. In Fiscal Year 2003, we will be billed for
$12,253.00. In Fiscal Year 2004, we will be billed for $27,517.00. In Fiscal Year 2005, we will be billed for
$3,194.00. The participants will send their portion of the payment to the SWCD, and the SWCD will send the
money far each fiscal year to the USGS. 'l'iming of the payments is to be determined, but likely will be in the fall of
each of the three years. A complete cost assessment is given in Table 1 of the enclosed proposal for this project that
is entitled: Kendall County Hydrogeologic Resource Assessment.
The breakdown of funding was determined as follows (over three years):
$10,000.00 Yorkville: Planning to use IEPA Radium Compliance Violation fine funds
$4,285.00 each Oswego, Montgomery, Plano, Plainfield, Joliet, County, Minooka
$ 601.00 each Lisbon, Newark, Millington, Sandwich, Millbrook
The City of Yorkville agreed to provide more than the other partners with the understanding that they will use their
IEPA Radium Compliance Violation fine money towards this project. If, for some reason, the City is unable to use
that fine money for the project, the City has requested that the extra amount they are putting towards this Phase I
groundwater study be credited to them if all agree to proceed with Phase II of the project.
So_the USGS can start the project on time, please review the resolution at your June meeti~and send the
el¢ned and dated resolution along with the completed contact sheet to the Kendall County SWCD, 7775A
Route 47, Yorkville 1Z 60560. If vau have any questions regarding this project, please contact Jen
Wiesbrook Resource Conservationist for the Kendall Count SWCD at either 630-553-5821 Extension 3 or
ien vviesbrook(a~il.usda.gov. Also, please let us know if you have an on- oin or lanned water project that
may provide additional information for the Kendall County Groundwater database.
Thank you for your partnership an this important project for Kendall County.
