Laboratory Testing Of Select Geotextiles As Biointrusion Barriers And Sediment Filters, David R. Beck
Laboratory Testing Of Select Geotextiles As Biointrusion Barriers And Sediment Filters, David R. Beck
Masters Theses
It has been proposed that placing a geotextile over sediments with adsorbed contaminants can prevent bioaccumulation of the contaminants in larger animals by isolating the benthic organisms living within these sediments from fish. In conjunction with a field study carried out at Gull Creek, a laboratory study testing two geotextiles as biointrusion barriers and sediment filters was conducted.
Constant-head permeameters were run for seven days using cores from the field study area with a geotextile placed over the cores. For biointrusion barrier tests, medium sand was placed over the geotextile and spiked with nutrients. Following each trial, benthic organisms in …
Application Of Geochemical Fingerprinting And Isotopes To Identity Landfill Gas Impacts To Groundwater, Eric E. Wallis
Application Of Geochemical Fingerprinting And Isotopes To Identity Landfill Gas Impacts To Groundwater, Eric E. Wallis
Masters Theses
Volatile organic compounds (VOCs) are detected in two groundwater monitoring wells (MW-60 and MW-62S) located along the northern, downgradient property line of the McGill Road Landfill (MRL) in Jackson, Michigan. Potential on-site sources for groundwater impact are two distinct landfill units at the MRL. Leachate chemistry suggested that landfill leachate was not the source of VOCs detected in groundwater. A potential source for VOCs was landfill gas. Sources of landfill gas in the vicinity of the impacted wells included the distinct MRL landfill units as well as the old Jackson County Landfill (JCL), located hydraulically downgradient from the impacted wells. …
Stratigraphy Of Lake Michigan Lobe Deposits In Van Buren County, Michigan, Steven P. Beukema
Stratigraphy Of Lake Michigan Lobe Deposits In Van Buren County, Michigan, Steven P. Beukema
Masters Theses
The surficial glacial deposits and landforms of Van Buren County were recently mapped at a 1:24,000 scale as part of a STATEMAP project. Several borings were drilled to supplement the surface data. Six of these borings were characterized in detail by means of gamma ray logging, textural analysis, and X-ray diffraction of the clay-sized fraction of the diamicton units.
Results from this study reveal two diamicton units at stratigraphically distinct positions that can be correlated across the county and that are separated by a thick sequence of lacustrine sediments. Correlation of diamicton and lacustrine units was accomplished by analyzing several …
