Leachate Monitoring In Naturally Saline Groundwater Chesapeake Landfill Chesapeake Virginia, T. Britt Mcmillan

OES Theses and Dissertations

Groundwater chemistry around the Chesapeake municipal landfill was monitored over a one year period. Ten sample sites as well as two surface water sites were used to monitor water quality. Two wells, one at 3 m and the other at 10 m were located at each site. Surface water samples were taken from the Elizabeth River, north of the landfill, and a tidal channel, west of the landfill. Seven groundwater sites were downgradient of the landfill and three sites were upgradient (control sites).

The landfill overlies a tidal marsh, approximately 100 m south of the intracoastal waterway (Elizabeth River). Dredge …

Chemistry And Apparent Quality Of Surface Water And Ground Water Associated With Coal Basins, R. B. Stroud, J. L. Spellman, R. R. Potts, A. J. Oakley

Technical Reports

Personnel of the Arkansas Mining and Mineral Resources Research Institute conducted preliminary investigations on the chemistry and quality of surface and ground water associated with 12 coal-bearing sub-basins in the Arkansas Valley coal field. The coal field is approximately 60 miles long and 33 miles wide but only in 12 areas coal is thick enough and has proper quality to be termed commercial. Both surface and underground sample sites were established in each of the sub-basins with some minor variations in four areas where not all types of sites could be located. Water was collected from 19 surface points and …

Institutional Arrangements And Financing Alternatives For State And Local Water Programs, Joseph A. Ziegler

Technical Reports

This study analyzes alternative institutional arrangements and financing alternatives for water projects at the state and local levels with particular emphasis on Arkansas. Because most water projects are financed with debt it concentrates on alternatives which can reduce the cost of debt and/or result in more efficient use of existing facilities. Specific state options considered include grants, loans, revolving funds, debt guarantee, bond insurance, bond bank, statutory and regulatory reform of water laws and water-related institutions, and planning and technical assistance. Specific local options include use of taxes and bonds including creative financing, user fees, leasing, privitization, and financial planning.

Optimal Allocation And Scheduling Of Irrigation Water For Cotton And Soybeans, M. J. Cochran, L. D. Parsch, J. M. Redfern, H. D. Scott

Technical Reports

This study evaluated alternative irrigation scheduling strategies for cotton and soybean production on Sharkey clay soils in southeast Arkansas. Strategies were ranked on the basis of two basic criteria: expected net revenue and risk efficiency. Risk efficiency was defined for different risk preferences using stochastic dominance techniques. Preferred strategies for cotton employed tensiometer thresholds between -.45 atm and -.75 atm. Risk efficient soybean irrigation strategies varied with the degree of risk aversion--more risk averse decision makers prefer strategies with lower thresholds.

Demonstrations Of Arkansas' Water Management Simulator, Leslie E. Mack

Technical Reports

One of the larger stumbling blocks to comprehensive water management is the lack of public understanding of the multitude of variables that operate at the same time within the hydrologic cycle. With more public understanding, there is greater public support for various water projects. Dr. John R. Amend from Montana State University developed a water management simulator which could handle a large number of variables simultaneously of natural surface and groundwater flow plus a number of water use variables on an accelerated time sequence. By using several remote control devices, participants can "control" their water use but have no control …

Analyses Of Groundwater For Trace Levels Of Pesticides, T. L. Lavy, J. D. Mattice, T. C. Cavalier

Technical Reports

Agricultural production is a major source of revenue in Arkansas. In order to increase productivity, it has been necessary to rely increasingly on the use of pesticides and irrigation water. In the last 15 years several states have reported finding pesticides in groundwater as a result of normal agricultural practices. Since almost half of the population also relies on groundwater as their source of drinking water, it is necessary to conduct research as to ascertain the presence or absence of commonly used pesticides in groundwater. Multi residue analytical techniques were developed for the analysis of acifluorfen, alachlor, atrazine, cyanazine, diuron, …

The Behavior Of Soluble Salt In Sharkey Clay, J. T. Gilmour, J. A. Ferguson, H. D. Scott, R. E. Baser

Technical Reports

Soluble salt problems do exist and are significant in Arkansas. Studies have been conducted on Crowley silt loam (Typic Albaqualfs) which have established the behavior of soluble salt in that soil. The major objective of this study was to quantify the behavior of soluble salt in a second important Mississippi River Delta soil - the Sharkey (Vertic Haplaquepts). To this end, estimation of the downward redistribution of salt and the estimation of various components of the water balance for this soil served as specific objectives. Field studies were designed to monitor the movement of salt in the Sharkey soil and …

Development Of General Guidelines For The Planning Of Stormwater Management Facilities: Application To Urban Watersheds In Kentucky, Lindell E. Ormsbee, Vincent T. Reinert

KWRRI Research Reports

This report provides a planning methodology and a design tool to help determine the appropriate location and volume of detention basins required to control critical storm events. The technique involves using watershed characteristics including the SCS curve number, time of concentration, peak outflow rate, watershed area and the storage recurrence interval to help predict these detention volumes.

Historical rainfall records are used in a revised continuous simulation program (SYNOP, Hydroscience, Inc,) to determine the rainfall excess from which runoff hydrographs are produced. Various combinations of the watershed characteristics were input and computer analyses done to obtain the required data base. …

Investigation Of Pollution In A Karst Aquifer Utilizing Optical Brightener, John Thrailkill, Ralph F. Wiseman, Bridget R. Scanlon

KWRRI Research Reports

Optical brightener is an additive to laundry detergents and is found contaminating groundwater. Its concentration may rapidly and inexpensively be determined by fluorescence techniques, and because its source is human wastewater, its presence in groundwater serves as a direct indication of pollution from septic tanks, sewer leaks, and landfills.

A total of 105 wells and springs in an area within the Inner Bluegrass Karst Region near Lexington, Kentucky, were described and sampled. Analyses were made for optical brightener (430 samples), total coliform (91), fecal coliform (93), and fecal streptococci (90). As many as 20 optical brightener and 4 bacterial samples …

Modeling Of Overland Flow By The Diffusion Wave Approach, Rao S. Govindaraju, S. E. Jones, M. L. Kavvas

KWRRI Research Reports

One of the major issues of present times, i.e. water quality degradation and a need for precise answers to transport of pollutants by overland flow, is addressed with special reference to the evaporator pits located adjacent to streams in the oil-producing regions of Eastern Kentucky. The practical shortcomings of the state-of-the-art kinematic wave are discussed and a new mathematical modeling-approach for overland flows using the more comprehensive diffusion wave is attempted as the first step in solving this problem. A Fourier series representation of the solution to the diffusion wave is adopted and found to perform well. The physically justified …

Identification Of Soil-Water Chemical Parameters For The Prediction And Treatment Of Suspended Solids In Surface Water Reservoirs Of Coal Mine Lands, V. P. Evangelou, J. H. Grove, R. I. Barnhisel

KWRRI Research Reports

High concentrations of suspended solids in coal mine sedimentation ponds are a factor in lowering water quality. Colloidal particle settling simulations were carried out in the laboratory to test the influence pH and dissolved solids have on concentration and settling rates of suspended solids. The results of the study reveal that the pH range of colloidal coflocculation for the samples tested is between 3.5 and 4.5. Furthermore, liming simulation of acidic sediments, as expected increased colloid dispersion. This increase was dependent on the magnitude of the sodium adsorption ratio (SAR). The greater SAR systems maintained a greater concentration of colloidal …
