Hydrogeology And Hydrogeochemistry Of The Tekonsha Moraine And Adjacent Interlobate Deposits In Charleston Township, Kalamazoo County, Michigan, Victor V. Melbardis

Masters Theses

Hydrogeochemical analyses and hydrogeologic interpretations provide the basis for an understanding of local ground-water flow, in a 12 square mile study area, transected by the Tekonsha Moraine and bound by glaciofluvial deposits. Glacial tills separate an upper and lower aquifer system throughout most of the area.

Degraded and tritiated ground water is present in the lower aquifer system. A negative correlation (-0.62) between tritium concentrations and depth is statistically significant (.04). In this local system, hydrochemical trends are characterized by decreases in sulfate percentages and increases in bicarbonate in the direction of ground-water flow. Statistical evaluation of the hydrochemical data …

The Hydrogeology And Leachate Generation Of An Alum Sludge Lagoon Chesapeake Virginia, Charles M. Darling

OES Theses and Dissertations

In 1986 the City of Chesapeake, Virginia began to dig shallow ponds ("lagoons") to contain alum sludge, a waste generated by the City from the process of treating potable water. Borings at the disposal site reveal that the near-surface geologic units include a thin mud-rich facies which overlies a thick sandy facies, both of which are in the Lynnhaven Member of the Tabb Formation. At 7 meters depth, a clay-rich facies of the Yorktown Formation (Morgarts Beach Member?) underlies the sandy water table aquifer. Water levels from twenty observation wells and two monitoring wells installed into the water table aquifer …

Simulation Of Bromide Transport In A Layered Aquifer Using Two-Dimensional And Three-Dimensional Computer Models, Kathleen Michelle Hewitt

Masters Theses

Simulation of a two-well tracer test at a site near Mobile, Alabama was performed and compared with the experimental breakthrough curve. The models used to simulate the test results were the three-dimensional USGS code HST3D and the two-dimensional USGS code MOC. The results of the three-dimensional model were also compared with the results of the two-dimensional model.

The three-dimensional model HST3D predicted the measured breakthrough curve accurately with the exception of early arrival times of the tracer in the withdrawal well. The two-dimensional model MOC did not accurately predict the bromide concentration in the withdrawal well during the two-well test. …

A “Drastic” Evaluation Of The Ground-Water Pollution Potential Of Karst Terrain: Lost River Ground-Water Basin, Warren County, Kentucky, David Baize

Masters Theses & Specialist Projects

Karst terrains, such as the Lost River Karst Ground-Water Basin, are extremely vulnerable to ground-water contamination. Seven physical factors: depth to water, recharge, aquifer media, soil media, topography, impact of the vadose zone, and hydraulic conductivity, are evaluated using the DRASTIC system to determine the ground-water pollution potential of the study area. A numerical value is calculated for each of the seven factors, and a map layer for each factor is produced. These layers are then “added” together to produce a DRASTIC ground-water pollution potential map. The effectiveness of each factor in evaluating the pollution potential of karst terrain is …

An earthquake is the result of an adjustment of the surface of the earth caused by a release of energy in the earth's crust. Faulting is one of many causes of earthquakes.

Seepage Interceptor Drains For Reducing Waterlogging And Salinity, Don Mcfarlane, Jim Cox

Journal of the Department of Agriculture, Western Australia, Series 4

Shallow interceptor drains can reduce waterlogging on sloping sites. Such drains will more than pay for themselves from the increased crop yield. Recent work has shown that these drains also decrease salinity so that they are cost-effective in the long as well as the short term.
