Generally, site characterization methods involve one-time field point measurements and sampling (or continuous measurements in the case of some geophysical methods) of physical and chemical properties of the subsurface, or multiple measurements to characterize seasonal variations at the site. This practical volume applies geophysical techniques to hazardous waste site investigations, highway bridge foundations, and water quality. Seven peer-reviewed papers in a section on Surface Geophysics and Borehole Geophysics discuss: • in situ soil testing • measurement of engineering properties in rocks and sediments •.
Provides information on where to go to find detailed guidance on how to use these techniques. Covers: remote sensing & surface geophysical methods; drilling & solids sampling methods; geophysical logging of boreholes; aquifer test methods; ground water sampling methods; Vadose Zone (VZ) hydrologic properties: water state, infiltration, conductivity, & flux; VZ water budget characterization 5/5(1). The most prevalent characterization methods used were geophysical logging methods. Characterization of a number of sites included laboratory analysis of borehole sediment samples specifically for radionuclides and other contaminants, and geologic and hydrologic properties. In some instances, more detailed research level studies were by: 6.

Office of Solid Waste and Emergency Response.;]. Expedited Site Characterization (ESC) has been developed, demonstrated, and deployed as a new time-saving, cost-effective approach for hazardous waste site investigations. ESC is an alternative approach that effectively shortens the length of the assessment period and may significantly reduce costs at many sites.

Geophysical Methods [3, 5] Six different geophysical methods were combined in eight borehole applications to collect the geophysical data for this investigation. The six methods were: natural gamma, gamma-gamma, total magnetic and magnetic susceptibility, electrical conductivity, and temperature.

Geophysical methods encompass a wide range of surface and down-hole measurement techniques which provide a means of investigating subsurface hydrogeologic and geologic conditions.
These methods have also been applied to detecting contaminant plumes and locating buried waste by: 3. Typically, one may apply multiple methods to refine the conceptual models. Use of multiple methods also hedges against one method failing to provide useful data. Types of geophysical surveys include surface and downhole (or borehole).

In addition, various methods can be used to collect gas-phase samples in the vadose zone to evaluate vapor-phase contamination. One component of site characterization that is often critical for sites contaminated by organic chemicals is determining if immiscible liquids are present in the subsurface.

Airborne geophysical methods that were developed for mineral and petroleum exploration can, with some modification, be applied to environmental problems where large areas must be characterized.

This guide does not describe the specific procedures for conducting geophysical surveys. Hazardous waste site characterization provides the information needed to identify site hazards and to select worker protection methods. The more accurate, detailed, and comprehensive the information available about a contaminated site, the more the protective measures can be tailored to the actual hazards that workers may encounter.
responsibility for the characterization and cleanup of hazardous waste sites had all adopted some form of expedited site characterization process by the end of the decade. One set of technologies that has found a natural application in the context of expedited site characterization has been geophysical characterization technologies.
Introduction. Old uncontrolled landfill sites are among the main causes of groundwater contamination worldwide (Cossu et al., ).Before possible remediation, proper site characterization is necessary in order to ascertain the areal extent and volume of the deposited waste, evaluate current leachate and biogas emissions, measure waste residual emission Cited by: 4.

Please note that within this document, the more commonly used terms, hazardous waste site and toxic waste site, are used synonymously with the term contaminated Size: 1MB.
Geophysical methods offer advantages, such as high temporal and spatial resolution, non (or minimally) invasive and cost-efficient operation, rendering them a very powerful tool for characterization, and long-term monitoring of waste disposal sites.
Since geophysical methods involve the indirect imaging of the subsurface cautious implementation Cited by: 5.A Site Characterization (SC) is DEC's first investigation of a site where hazardous waste has or may have been disposed of illegally or improperly.
The goal of the SC is to determine whether a site meets the state's definition of a hazardous waste site by confirming or denying the presence of hazardous waste and determining whether or not the.Geotechnical and Geophysical Site Characterization 4 – Coutinho & Mayne (eds) (geophysical methods) in order to aid in the char- investigation of hazardous waste sites are .
