Reed ABSTRACT Descriptions of the character and sequence of materials and tables listing their relative density, consistency, moisture content, and size analyses are presented for glacial materials sampled and tested as part of a controlled drilling program for ground-water exploration at seven sites in Lee County and one site in Ogle County, Illinois. The results of 16 re- fraction seismograph profiles and preliminary data from a pumping test at one test-hole site are also given for Lee County. INTRODUCTION In the Chicago region and in other areas of northern Illinois the deep sources of water, the artesian sandstones, are already overpumped. The purpose of a drilling program conducted in Lee and Ogle Counties by the Illinois State Geological Survey was to provide information on the nature of glacial de- posits to facilitate the search for new, shallow sources of ground water for the rapidly expanding metropolitan areas of northeastern and north-central Illinois. Data compiled from field and laboratory analyses of samples collected from one test hole in Ogle County and seven drill holes, l6 refraction seismograph pro- files, and one pump test in Lee County are presented here (fig. l). The test holes were drilled in conjunction with the construction of a test well and an aquifer-evaluation study by the Illinois State Water Survey. The Geological Survey's role in the investigation was to obtain, by controlled drilling, sampling, and testing, detailed information on the glacial deposits in two buried valleys, the Paw Paw Valley in Lee County and the Rock Valley in Ogle County. Both valleys were believed to have a reasonably good potential as a source of ground water. Previously, little test drilling had been done to determine the nature of the valley deposits and their ground-water potential. The Lee County drill holes and seismic stations were located to better define the shape, depth, and character of the glacial fills of the Paw Paw Valley. - 2 - R I E R 2 E Section location grid # Drilling site (•) Pump test site X Seismic station 5 Miles ' 1 i 1 ' 1 1 -j- "f- --{■-- 8 7 6 5 4 3 2 Fig. 1 - Location of drilling sites in Lee and Ogle Counties. The Illinois State Water Survey- has made quantitative appraisals of the water -yielding potential of the glacial deposits at selected sites. In subsequent reports the Geological Survey will present geologic interpre- tations of the data reported here. The results of controlled drilling programs conducted in 1962-63 and in 1970 were reported in earlier Environ- mental Geology Notes (nos. 2, 6, 7, 9, 10, and 53). Data from this investigation can be applied to other environmental problems in the region in addition to the availability of ground water. This investigation (l) supplements existing information on the character and dis- tribution of glacial materials that may be usable mineral resources, that may present construction problems , or that may affect the disposal of wastes; and (2) provides a basis for inter- preting other types of subsurface in- formation, such as drillers' logs of water wells or records of foundation borings. For example, the drilling provided representative, relatively undisturbed split-spoon samples of earth materials that can be used to determine the physical and chemical properties that commonly affect land use. The exploratory drill holes and the experimental well work were done by Layne-Western Company of Aurora, Illinois , under supervision of the Geological Survey. At one site, the State Water Survey conducted a pumping test on a well constructed and devel- oped by J. P. Miller Artesian Well Company of Brookfield, Illinois. Locations for the test holes se- lected by the Geological Survey were generally along the rights-of-way of county roads. Landowners and utility companies were consulted about buried tiles , cables , and pipelines in the area. County and township road super- visors , county zoning and planning officials, and county health officers were apprised of the scope, progress, and results of the testing. - 3 - FIELD OPERATIONS Drilling The drilling contractor was provided with a log of the anticipated thickness and character of the deposits extending to bedrock, instructions on testing procedures , and a schedule of depths to be sampled with a split-spoon sampler. A mobile Sanderson-Cyclone hydraulic rotary drill rig was used for the drilling. The support equipment consisted of an l8-foot tilt trailer, a 1,000-gallon flat-bedded water truck, an enclosed 12-foot test site trailer, and a 1^-ton truck with a rear mounted backhoe. The crew at the rig normally was made up of a driller, a driller's helper, and a Survey geologist. During drilling, conventional rotary samples were obtained, split-spoon samples were taken at selected intervals, and a log was made of the materials penetrated. Interconnected settling and suction pits of about equal size were used during the program to keep the drilling mud at optimum viscosity and weight. The mud losses between work periods and during drilling were recorded for each boring. Natural mud alone was used to start test holes, but eventually bentonite and, periodically, caustic soda were added to improve mud properties. Density and viscosity of the drilling mud were determined with a standard mud balance and a Marsh funnel. Sampling Rotary samples were collected at 5-foot intervals from the open ditch near the drill hole. The drilling mud was circulated until a representative sample was collected from each interval. The samples were washed in a 5-gallon bucket, air dried, and then bagged. Split-spoon samples were obtained with a sampler having an outside diameter (OD) of 2 inches. The split-spoon was lowered inside a full-hole U%- inch OD drill pipe on AW-Rod (OD 1-1 inches) with flush- joint straight thread. The spoon was then driven 18 inches by a lUO-pound hammer that fell 30 inches or, where noted, by a 300-pound stem and jar that fell 27 inches. The rotary cuttings and split-spoon samples obtained at approximately the same intervals vary considerably in texture (grain size), as illustrated in figure 2. The rotary cuttings were almost invariably coarser as a result of the finer sediment being washed out and many were more poorly sorted (of less uni- formly sized grains) as a result of being collected from a greater vertical interval than the split-spoon samples. The rotary cuttings and the split-spoon samples are on file at the Geological Survey. Measurements of the unconfined compressive strength of cohesive materials (primarily clay till) were made on each split-spoon sample with a Soiltest Model CL-700 pocket penetrometer immediately after the sample was obtained. A small portion of each cohesive sample was sealed in a bottle for later determination of natural moisture content. - k - «a- T in in in — in o o CO sO _ in csj CO in co in csi in in CO CO CSJ CSJ CO O o CO I o_ c: CSJ in co •3\5.(!'

ELECTRIC AMD NATURAL GAMMA LOGGING Spontaneous potential (SP), single-point resistivity, and natural gamma logs were run in mud-filled test holes with a Neltronic logger (IK Model D) The logs, which are on file at the Geological Survey, were useful in the inter- pretation of the lithologic sequence, character, and thickness of the glacial deposits sampled and tested in the program. Seismic Investigations Sixteen refraction seismograph profiles were made in southeastern Lee County to determine the depth to bedrock. The seismic stations, which had spreads of geophones ranging from 1,200 to 2,300 feet with 100-foot geophone spacing, were generally located beside level roads. A list of each seismic station and corresponding surface elevation, depth to bedrock, and bedrock elevation, with comparative data from five test holes, is given in table 1. Depth to bedrock was calculated by the conventional time-intercept method. Bedrock depths at five of the seismic stations corre- lated favorably with results obtained from drilling. The seismic investigations were supervised by Paul Heigold of the Geological Survey staff. LABORATORY TESTS Size-Distribution Analyses Hydrometer analyses were used to determine the amount of clay (particle diameter less than 0.0039 nim) in each cohesive split-spoon sample. Samples of approximately 55 grams were taken, and corrections for temperature and added deflocculants were made. The amount of material coarser than silt (diameter greater than 0.0625 mm) was determined by sieving, and the amount - 6 - TABLE 1— SEISMIC STATIONS, LEE COUNTY, ILLINOIS Location Surface Depth to Bedrock elevation bedrock elevation (ft) (ft) (ft) 850 275 575 870 381 489 950 473 477 930 385 545 955 449 506 930 466 464 905 431 474 945 405 540 920 398 522 9^5 434 511 945 510 435 930 515 415 91+O 1+71 469 825 333 492 920 451 ^59 7I5 239 506 Comparative test-hole data SW£NE£ sec. 29, T. 38 N., R. 2 E.

The rotary and split-spoon samples that were friable and noncohesive were sieved with Tyler screens. The dimensions of the sieves and the Wentworth and phi () grain-size classifications related to this study are shown in table 2. The upper size limit of the sieved material was about 30 mm in diameter. IDENTIFICATION SYSTEM The numbering system used to identify the borings is based on the location of the boring. The number of each hole consists of a county abbrevi- ation, township, range, section, and coordinates within the section. Sections are divided into rows of one-eighth of a mile squares. Each square contains 10 acres and corresponds to a quarter of a quarter of a quarter section. A normal section of 1 square mile contains eight rows of one-eighth mile squares, and, of course, an odd-sized section contains more or fewer rows. Rows are numbered from east to west and lettered from south to north as shown in the grid on figure 1. For example, a well located in square 5d of Section 29, Township 38 North, Range 2 East, Lee County, would be numbered LEE 38N2E-29-5d. - 7 - TABLE 2— SIEVE DIMENSIONS AND GRADE SCALES Sieve number Wentworth grain-size classification U.S. Tyler mesh diameter Phi (<}>) Standard Tyler (in.)

The borings have been located within the 10-acre coordinate squares with as much accuracy as the scales permit, according to footage locations made by the field geologist. The quadrangle topographic map on which the boring is located is identified in the drill record. Elevations for each boring and seismic station were estimated from contours shown on the topographic maps.
