Sanderson Adrian Visocky Engineer Hydrologist BACKGROUND • • •• An important public. and industrial source of groundwater supplies in northeastern Illinois (a region including Cook, DuPage, Kane, Lake, • McHenry and Will Counties) is the Cambrian and Ordovician bedrock (often referred to as the deep sandstone aquifer). The upper water-bearing units • of the aquifer are encountered at an average depth of approximately 500 feet and the thickness' of the aquifer averages about 1000 feet. Lithologies within the Cambrian and Ordovician bedrock include sandstone, dolomite -and shale. The principal water-bearing units .are the clean . sandstones including the Glenwood-St. Peter -Sandstone, the Ironton- Galesville Sandstone, the Elmhurst Sandstone Member of the Eau Clair - Formation and the upper section of the Mt. Simon Sandstone. Regionally,- . : the most productive unit is the Ironton-Galesville Sandstone. When the first wells .were drilled in the Cambrian and Ordovician bedrock (1860s),-the artesian pressure was sufficient to cause wells to flow in the Chicago-Joliet-Fox River Valley area. However, by 1980 water ' levels in the. deep sandstone aquifers had de'clined. by more than 900 feet in some localities of northeastern Illinois, and significant dewatering of • the upper units in the Cambrian and Ordovician bedrock occurred in major • pumping. centers at Aurora, Elgin, .and Joliet and in eastern DuPage County • • - and northern and western Cook County' (Visocky, 1982). - If water levels . - decline below the top, of .the rontcn-Galesville sandstone then yields of. • . • wells will decrease drastically. . Recently there have been increases in the allocation of water from Lake Michigan for public supplies; these allocations will reduce the decline in water levels in the Cambrian and Ordovician -bedrock. in Cook and DuPage Counties. However, despite_ the lake allocations., pumpage will • continue to exceed. the practical sustained. yield (6.5 million gallons per day) and it is projected -that by the year -2O20 critically low water levels will occur in Joliet and at communi=ties along the. Fox River in Kane County • - •(Visocky, 1982). • There are also concerns related to- certain: as.pects- of the chemistry . .of groundwater from the Cambrian and- Ordovician bedrock. The. element barium occurs in groundwater from this aquifer .at concentrations in excess - of the drinking .water standard of 1 mg/L over- large areas of Kane and McHenry Counties, the eastern -part of DeKalb County, and the western parts . of Lake,. Cook, and DuPage Counties (Gilkeson, Perry and Cartwright, 198.1). • Additionally, analyses have determined that the radioactive. elements radium-226 and radium-228- occur widespread in-northeastern Illinois. in groundwater from the Cambrian and Ordovician bedrock at combined- - concentrations significantly greater than the drinking -water standard of • . 5' pCi/L (Gilkeson, 'et al. , in preparation). - • - . Because .of concerns'.ior.-.he -declining water levels and for .the dele- • . terious water quality in- the Cambrian and Ordovician bedrock, .there is need for information on the availability of groundwater from other . • aquifers in Kane County. . These aquifers, which -overlie .the .Cambrian and • . Ordovician bedrock, are thick deposits of sand. and .gravel in .the glacial - • - drift and fractured dolomite in the shallow bedrock. The shallow aquifers • . - are not; uniformly present- throughout the entire county. Exploration is necessary to determine their thickness, regional :extent, .and.iaater supply capabilities. STATEMENT OF PROBLEM Shallow Aquifer System The shallow aquifer system in Kane County is composed of sand and gravel deposits of glacial origin and fractured. dolomite bedrock of • ' Silurian and Ordovician -age. The unconsolidated geologic materials are • referred to as glacial_ drift. In Kane County, the thickness- of these materials is greater than 350 feet in. some localities although at some • - . localities along the Fox River, the glacial drift_. has. been eroded exposing: V the dolomite bedrock. : Over large regions of the county the glacial drift . is over 100 feet thick. The glacial drift is primarily composed of a • - ' geologic material that is. a mixture of sand and gravel in a .clayey matrix • , (glacial till). The till was deposited directly by glacial ice during • glacial advances. Large supplies of groundwater are available where thick, regionally extensive deposits' of sand and gravel are present in the • glacial drift. One promising location for sand and gravel deposits is in . burled valleys 'Incised into the bedrock. The major bedrock valley in Kane . . County. is referred to as the Newark Valley: .St. Charles and South Elgin • • have municipal wells that are finished in sand and gravel deposits present in the Newark Valley (see figure 1). The city of Aurora also has a municipal well finished in sand and 'gravel .present in a buried bedrock . • . valley that flanks the south side of the city (fig. 1). The last glacial events produced sand and gravel deposits. that have an expression on the • present land surface. Thick sand and gravel deposits are also present 'in 'depositional environments within the glacial drift. . These sand and gravel *deposits are not •detected by mapping the bedrock surface. It'.is also important to note that thick sand and gravel deposits occur at localities . throughout the county; the. shallow groundwater resource is not restricted to the eastern part' of Kane County. . • • An environment that may provide large .supplies of groundwater in southeastern'Kane' County and, adjacent .regions of DuPage and Kendall Counties, is where 'extensive deposits of -sand and gravel directly overlie dolomite bedrock. In this setting, wells finished in crevices and . . fractures in the .dolomite bedrock may have high yields of groundwater. In this environment, .the wells produce groundwater from both the glacial - drift and -the shallow' bedrock. ' The shallow groundwater resource_-in the region of.Kane County- is greatly under—utilized at 'Vile present time. The yield potential of the . . • shallow groundwater resource.'in the six—county region of northeastern Illinois is estimated 'to be 455 million gallons 'per day (Schicht, .et al., ' 1976). . However total-withdrawals in 1980. from the shallow groundwater resource for the region were measured to be only 158 million gallons per day (Kirk,. et al. , 1982) . Only in DuPage' County. is the shallow- resource '.' - - hallow resource- • fully utilized at the 'present time. o FIGURE 1. .

Corrected approximate location of the axis of the major bedrock valley T••• (NEWARK VALLEY) .based on new well information and application of . ,• • seismic refraction •y Shallow Groundwater Exploration' The Geological Survey Division conducted a controlled'drilling. pro- gram.in Kane County in the early 1970s to evaluate the groundwater . • resource in the major bedrock valleys (Reed, 1975). The test holes were located on the basis of the bedrock surface map prepared from an inventory of well data by•Horberg (1957) . Some of the test holes documented the presence of sand and gravel in the buried valleys. Several of the .test holes were not successfully 'located over the valley. It was 'discovered • ' • that the well inventory did. not accurately locate the buried -valleys. It was also discovered' that in some localities the buried valleys were filled with fine-grained - geologic materials; thick sand and gravel:-deposits were . ' . not present. . . An accurate. evaluation of 'the shallow groundwater resource requires . .. knowledge of the thickness and regional extent of sand and .gravel deposits, the drilling of test holes to -sample the. sand and:. gravel •• . - deposits, sieve analysis of .these deposits for well design, the . construction of test wells and the performance. of. aquifer tests. . Determination of the thickness and regional extent -of sand and gravel ' deposits by drilling exploratory holes is a very expensive venture. " The cost. at .the present• time for drilling a single test hole to a depth of 200- . feet with collection of 20 split' spoon samples of the unconsolidated geologic materials would be in the range of $4,000 to $4,500. . . Recent advances in surface geophysical methods allow the accurate, - economical application .of these techniques to evaluate -the shallow . . . . groundwater resource in Kane County. .The geophysical, techniques greatly reduce the' number of exploratory borings necessary: The techniques are . • . applied to define the •regional extent of thick sand and gravel deposits • -and select sites for the construction of test wells. In the past three years, ' the Geological Survey Division has tested . • the application .of the seismic method in Kane. County. In the southern . part of Kane County, it 'was determined that an earlier interpretation- of ' the location of, major bedrock valleys made from. the study of .well. records • • was incorrect (see figure 1). Furthermore, .the seismic. method determined • that the bedrock valleys are quite narrow in some localities and extensive information is necessary, to accurately map their. location. The seismic method is capable of supplying the needed information. The seismic method accurately determines' the total. thickness of the . - . glacial drift but does not provide information on the presence of sand and gravel. The lithology of the glacial drift can be investigated through the application of another surface geophysical method, electrical earth resistivity. 'The electrical properties of fine-grained clayey materials - . are different from those of thick sand' and 'gravel- deposits. However, the . ' - electrical properties of the sand and gravel deposits are similar• to the - . electrical properties of...thP dolomite or shaley. dolomite bedrock in Kane .' County. Therefore, evaluation of both the thickness of the glacial drift .and the presence of . sand and gravel requires application of both •geophysi- . cal .methods. . . • • Aquifer testing follows geophysical exploration as the next step in . investigatifig' shallow groundwater resources. Aquifer tests typically consist of pumping a well at a constant rate and .measuring its effect on • . . water levels in nearby observation wells. Data collected during such tests are analyzed to determine aquifer hydraulic properties .which are needed to assess the potential yield of the aquifer. In this -initial study, . testing will be conducted on available wells following an inventory and field reconnaissance of existing installations. Chemical, anal'yses will be - Performed .on groundwater .,samnlps collected during the aquifer tests. SCHEDULE This proposal is for a. 33-month study from September 1983 to May .30, 1986. The study includes two field seasons for the performance of surface geophysics. and aquifer tests. Data from the first season of field work will be interpreted and applied to refine the work performed during the second field season. . . PRODUCTS - •• - An important product of •the present proposal is an'.initi-al evaluation of the quantity and quality of groundwater available- from the shallow aquifer in Kane 'County: The evaluation .will be a synthesis of information . from the application of geophysics, information from new aquifer tests on existing wells, and information in the existing data base- (aquifer tests,, exploratory test holes and water well' records). The findings of the . • . project will be presented An a report :prepared by .the two Survey' Divisions. - • ' V ' ' . An. additional product of the geophysical exploration. program is the ' ,: .. development of a framewerk 'f&_. guiding future evaluation.. Localities in - the, county that have high' potential to provide large groundwater supplies -and warrant construction of test wells will be identified. A program to • _ construct test wells and: perform aquifer tests would, be the next step in a • . comprehensive evaluation of the. shallow groundwater resource. However, the well 'test program could proceed on a county-wide basis .or as an- effort • . in specific localities sponsored by, individual Municipalities or private- interests.

There is a. need for.an evaluation of other water • resources in the region of the county because of declining water levels in the - Cambrian and Ordovician bedrock as well as concerns. for water quality (high concen- trations of radium and barium) . The significant resources for evaluation are 1) sand and' gravel aquifers in the glacial deposits and 2) the Fox River. An additional • • minor resource in so a 'parts of the county •are aquifers in the shallow dolomite -bedrock (-Silurian Dolomites and-. dolomite- in the Maquoketa- Shale Groua) , • • Communities along the Fox River that use sand' and gravel. aquifers as. a ' s.i4nificant groundwater resource. include Carpentersville. East Dundee, West Dunde-:, South Elgin and St. Charles. Elgin .is the only community in Kane County that uses water from the• Fox_ Ri•ver. Elgin -began. treatment of. river water in March 1983, and • • presently the river provides about 75% of Elgin's water supply. Prior' to operation: ' of the river water treatment plant, all of Elgin'-s water supply was provided from .the Cambrian and Ordovician bedrock. ' • • • . The trend in the future will be for an increase in withdrawals from sand • .and gravel aquifers or from the river and a decrease in withdrawals from the Cambrian : and Ordovician bedrock.' This shift in source will have an impact. on the Fox River. . Of special concern.are water quality and -.discharge during periods of low flows. The aquifers in the Cambrian -and Ordovician bedrock are not 'in open hydraulic connection . with the Fox River; therefore, groundwater pumped from these deep .aquifers' is an additive component to 'river flows due -to effluent discharge' from sewage treatment • plants. The relation between- shallow aquifers (sand and gravel in-the glacial • - 3 - • deposits and the dolomite. bedrock). and the Fox River is. not well known. .Some of these aquifers-are in open hydraulic connection with th_ .river while others are ' separated from the river hy thick deposits or Llayev. glacial- till or possibly, by fine-grained alluvial sediments in the river channel. Large withdrawals from shallow • aquifers that are in .open.hydraulic connection. may significantly reduce the natural . • discharges from these aquifers to the river. In extreme. cases, the large .withdrawals .may reverse hydraulic gradients and induce recharge of river water into the shallow aquifers_. However.' withdrawals from shallow aquifers that are not in. open hydraulic . ' connection with the Fox River may result in a beneficial effect on. low flows in the . Fox River .due to their addition to effluent discharges. • • • - . An accurate assessment of the impact on the Fox River that would result from. a major change in the source of water resources in Kane County (a change in. source froth the deep. Cambrian and Ordovician bedrock to shallow aquifers or to the • Fox River) requires a comprehensive study.of' l) the regional groundwater .resource in the glacial materials and .2) the hydraulic interaction of the glacial.materials with the Fox River. In September 1983, the Illinois State Geological Survey and the ' Illinois State Water Survey began a 33-month study of the groundwater resource in the glacial materials within the region of Kane County. A comprehensive study of the hydraulic interaction of the glacial materials 'with the Fox River for an assess- ment of conjunctive use of the total water resource consists of the follow_ing_.four tasks: • • ' 1. Geologic mapping of the glacial materials along the Fox River 'Vallev. . to define'hydrogeologic environments. . • • • 2. Study of the variation in base flow accretions along- the Fox River, low-flow regime. water quality, and the effect. of changes. in water • supply .sources. - • • 3. A program of pump tests and modeling. to quantitatively define the • `hydraulic interaction of _the sand and gravel aquifers-with the Fox • River - • • • • 4 • 4. Synthesis .of all information from Tasks 1, 2 and 3, and other studies to evaluate the impacts of various scenarios of shallow groundwater use and water withdrawals from the river. on the low flows in the Fox, -and to conduct economic analysis for each scenario. • This proposal presents scopes of investigation - for Tasks 1 and 2. .The• .. two tasks will provide valuable. information without performance of Tasks 3 and 4 . However, the information provided by Tasks 1 and 2 is necessary for the design of Task 3, and Tasks 1,. 2 and 3 provide information that is necessary for Task 4 .- . This -proposal presents a- budget for a project of. one year duration to accomplish Tasks- 1 and .2. Brief preliminary scopes of investigation are also pre- sented for Tasks 3 and 4. Detailed"information. about these two tasks and budgets cannot be presented at the present tithe because the design of -these tasks requires . -information from performance of Tasks 1 and- 2. • TASK 1 • • . Mapping of. Hvdrogeologic Environments Along the • Fox River-Valley in Kane County Principal Investigator - Robert H. Gilkeson •. - Illinois State Geological Survey • SCOPE OF INVESTIGATION - • • . • •,Task 1 will be coordinated, with- an existing geophysical mapping program . for Kane County that is funded by the' State Geological Survey and municipal and county governments, of Kane- County. The geophysical mapping program is. designed to identify - - localities where there is potential 'for large supplies.of groundwater from. sand and . gravel deposits in the glacial .maxe.rfa-is. .The- scope of work presented in this new - proposal is an enhancement of the geophysical mapping piogram. to -investigate the • • - 5 - • . interconnection of the. sand and gravel aquifers wi•th .the Fox River. The accomplish- • ment of this objective requires three-dimensional mapping.-o.f the geologic materials t� define the areal_ distribution af. n. the coarse-.grained sand and gravel .deposits . . (aquifers) and 2) .the fine-grained gi.icial tills (aquitards) . The enhanced program • will define 1)' where there is potential for the sand .and gravel .aquifers to be- in - open hydraulic connection with the Fox. River and 2) .where. these sand and gravel aquifers are separated from the river by- thick deposits .of clayey glacial till. The• geonhysical mapping program will be -enhanced along the Fox River by • 1_) increasing the period of time for field study by six weeks. and 2) purchase -of a . portable data storage system. _During the performance .of field -studies the data- . ' • 'storage system is interfaced -with the seismic instrument and records the energies of- seismic waves directly onto IBM computer tape. The advantages of using the data storage system include 1) more rapid field .methods because the system collects simul- taneous records of both refracted and reflected seismic waves, -2) . the- system collects ' • a more complete record of the seismic waves generated, and therefore provides a more . accurate resolution of the geologic materials, 3) very efficient storage of field data (a single -reel of tape will hold the records from over 140 measurement stations) , . 4) increased accuracy and efficiency' in interpretation because the field data can be • - • entered directly into computers and importantly 5) -the data storage system will also increase the amount of seismic measurements (and improve -the quality of these ' measurements) that are performed in the countywide geophysical. mapping program. - The geophysical mapping program. will be integrated with- other sources of • information that include 1) driller's records, -2) soil maps, and 3) geolo.gic 'maps - of shallow .geologic materials to- produce the following- productsfor the Fox River Valley region: . . . • • • . - 6 - • 1.

' SCOPE OF INV• ESTIGATION S The magnitude of low-flow accretions to the -river flow from Algonquin to downstream of Aurora will be investigated to define reaches of .high baseflow . • accretions. The effect of shallow groundwater development on these. accretions can • then be assessed. Thsv may lead to demarcation of areas where groundwater develop • - . , went may have less effect on the river flow. Combined with . the considerations of . . . the quantity -of flow is the consideration of the water quality. The Jive items to be • addressed in Task 2 are described briefly as follows.: • 1. Detailed low-flow measurements will be made at five locations ; . • along the ;Fox River,. starting .from Algonquin to downstream of Aurora, during .dry ,weather conditions. The concurrent flow in tributaries will be measured and treatment. plant 'e.ffluent dis- • charges will be obtained. 'The water budgets- for the various . • - - 7 - reaches will be made to assess the baseflow accretions in respective reaches. Another set of flow measurements during dry weather conditions will be made to further improve the information and to• fill any gaps indicated by the first set of measurements. 2. The historical daily flow data at Algonquin and Dayton will be adjusted to the present condition of withdrawals and returns to define present flow duration and low-flow frequencies. The effect of some other towns switching from the deep sandstone aquifer to the Fox River for their water supply will be estimated in terms of low-flow statistics for the Fox River. 3. The available, water quality. data from 1970 onward for the Fox River in Kane County 'and some distance upstream and downstream will be analyzed, and the changes will be investigated in terms of effluent quality and source of water supply. 4. A thorough search and review of the publications relevant to this study will be made. The historical review will be helpful in evaluating the developments, improvements, and changes which have affected river flow • regime and 'river water quality. 5.
