    • Groundwater resources in Champaign County

    • 1950; Groundwater; ISWS RI-6; Municipal water supply; Smith, Harman F.; Water table; Wells
    • This investigation is part of a state - wide investigation of groundwater resources being conducted by the State Water Survey Division. Records of more than 1400 wells have been tabulated. These wells penetrate one or more of three separate and...
    • Leaky artesian aquifer conditions in Illinois

    • 1960; Aquifer; Aquifers -\- Testing; Cambrian-Ordovician aquifer; ISWS RI-39; Walton, William C.
    • Most if not all of the so called artesian aquifers in Illinois are actually leaky artesian aquifers. If the permeability of the confining bed is very low, vertical leakage may be difficult to measure within the average period (8 to 24 hours) of...
    • Selected analytical methods for well and aquifer evaluation

    • 1962; Groundwater -\- Analysis; Groundwater flow -\- Mathematical models; ISWS B-49; Walton, William C.; Wells
    • The practical application of selected analytical methods to well and aquifer evaluation problems in Illinois is described in this report. The subject matter includes formulas and methods used to quantitatively appraise the geohydrologic parameters...
    • Ground-water levels in Illinois through 1961

    • 1963; Groundwater; ISWS RI-45; Russell, Robert R.; Water levels; Wells
    • Systematic measurements of ground-water levels in Illinois were started in the early 1930s in the Chicago region. Measurements were made in 1961 in 220 observation wells in 42 counties throughout the state. In areas remote from pumping centers, no...
    • Groundwater resources of the buried Mahomet Bedrock Valley

    • 1969; Aquifer; Aquifers; Geologic; ISWS RI-62; Mahomet Sand aquifer; Mahomet(Teays) Bedrock Valley; Visocky, Adrian P., and Richard J. Schicht; Water resources development; Water-supply; Wells
    • The buried Mahomet Bedrock Valley and its major tributaries cover an area of about 3700 square miles in east-central Illinois. Large supplies of groundwater chiefly for municipal use are withdrawn from wells in permeable sands and gravels in thick...

    • Wells and pumping systems for domestic water supplies

    • 1973; Gibb, James P.; ISWS C-117; Water-supply, Rural; Wells -\- Design and construction
    • This circular presents basic information on wells and pumping systems used for farm and domestic groundwater supplies. It describes types of wells and their construction, development, and costs. It discusses the various types of pumps and pressure...
    • Ground-water investigation for the University of Illinois

    • 1999; Burch, Stephen L., Robert D. Olson, and Adrian P. Visocky; Geophysical well logging; Groundwater; ISWS CR-636; Water quality -\- Analysis; Water resources development; Water-supply
    • In 1997, the Illinois State Water Survey, at the request of the University of Illinois, initiated a test drilling project that included the construction of several 2-inch diameter observation wells at two sites on the Urbana-Champaign campus. The...

    • Impact of irrigation on the dynamics of nitrate movement in a shallow sand aquifer.

    • 1999; Groundwater -\- Pollution; Groundwater -\- Sampling; Groundwater flow -\- Mathematical models; ISWS RR-128; Irrigation; Kelly, Walton R., and Chittaranjan Ray; Nitrates -\- Environmental aspects
    • A field-scale project in Mason County, Illinois, was performed to monitor the movement of nitrate in ground water beneath an irrigated field. Chemical tracers were used to assess the migration of solutes both laterally and vertically under the...
    • Sidestream elevated pool aeration (SEPA) stations: effects on in-stream dissolved oxygen

    • 2000; Butts, Thomas A., Dana B. Shackleford, and Thomas R. Bergerhouse; ISWS CR 2000-02; Reservoir; Water -\- Aeration; Water -\- Dissolved oxygen; Waterloo Reservoir (ISWS - Monroe County)
    • As a result of increased pollutant loading and low in-stream velocities, dissolved oxygen (DO) levels in the Chicago waterways historically have been low. In 1984, the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) issued a...
