The Relation Of Radium-226 And 228 To The Groundwater Geochemistry Of Carbon, Sulfur, And Chlorine Near Michigan's Saginaw Bay, Ray Milejczak
The Relation Of Radium-226 And 228 To The Groundwater Geochemistry Of Carbon, Sulfur, And Chlorine Near Michigan's Saginaw Bay, Ray Milejczak
Masters Theses
The Michigan Department of Public Health (MDPH) sampled 149 residential wells producing from glacial drift and Saginaw Formation aquifers in Bay, Midland, Saginaw, and Tuscola counties in 1987. These wells were analyzed for 226Ra, 228Ra and general chemistry. Of the 149 samples, 50 exceeded the USEPA MCL of 5 pCi/L or greater for combined 226Ra + 228Ra activities. A geochemical model (WATEQF, Plummer et al., 1976) was used to determine activity coefficients, activities, ionic strength, and mineral saturation. The radium isotopes were statistically analyzed with respect to the chemical data from MDPH and the geochemical model …
Wetland Study Of Southeastern Portage Township, Kalamazoo County, Michigan, Kevin M. Walsh
Wetland Study Of Southeastern Portage Township, Kalamazoo County, Michigan, Kevin M. Walsh
Masters Theses
Under the Clean Water Act, Congress passed legislation to maintain and restore the chemical, physical, and biological integrity of the water of the United States. The objective of this study is to determine if the wooded area located in Upjohn Company's Property in southeastern Portage Township, Portage, Michigan falls under the classification of a wetland.
This objective has been pursued through an examination of the hydrology of the area, the soil characteristics of the area, and the vegetation types and characteristics of the area. These parameters have been utilized following the guidelines outlined in the "Corps of Engineers Wetland Delineation …
A Laboratory Characterization Of Pulp And Paper Mill Solid Wastes For Potential Use As Hydraulic Barrier Material In Landfill Covers, Carleton Van Maltby
A Laboratory Characterization Of Pulp And Paper Mill Solid Wastes For Potential Use As Hydraulic Barrier Material In Landfill Covers, Carleton Van Maltby
Masters Theses
Fifteen sludges from wastewater treatment systems of pulp and paper mills that encompass major production categories, and eight fly ashes from mill boilers incinerating wood waste, coal, or their combination were characterized for their potential suitability as hydraulic barrier material. Hydraulic conductivity was observed to range over four orders of magnitude for the materials tested.
Resistivity And Seismic Refraction Surveys Applied To A Groundwater Investigation In Richland Township, Kalamazoo County, Michigan, Homa Moaddel
Masters Theses
Many geophysical methods are increasingly being applied in investigations of contaminated sites. Among the most popular ones are resistivity and seismic refraction techniques.
In this study seismic refraction utilizing a twelve channel digital seismograph and hammer impact source provided records that have given important information about the subsurface layers. Along the same traverses, the Schlumberger resistivity method was applied at selected points. An AC digital resistivity system with a separate uncoupled transmitter (50 watts) and receiver was applied to obtain these measurements.
Geoelectrical cross-sections provided information about the variation in thickness of important layers within the glacial drift aquifer system. …
