“…An overview of f~-methods for environmental monitoring is given before the proposed approach is presented. Many investigators (Barker 1990;Berk & Yare 1977;Blum 1989;Buselli et al 1991;Carpenter et al 1990;Cartwright & McComas 1968;Cartwright & Sherman, 1972;Grady & Haeni 1984;Hackbarth 1971;Hughes et al 1971;Kelly 1976;Klefstad et al 1975;Rogers & Kean 1980;Rumbaugh et al 1987;Seitz et al 1972;Stollar & Roux 197,5;Urish 1983;Warner 1969 and so on) have demonstrated that electrical resistivity methods can be used to define the vertical and lateral extent of a contaminated groundwater plume. In these investigations, surface resistivity profiling and sounding have been mostly used to identify contaminated plumes from landfills.…”

“…Mazac et al (1990) mapped the lateral extent of oil contamination, and Schneider & Greenhouse (1992) in an experimental field set-up tried to follow the downward movement of dense, high resistivity, non-aqueous contaminants. D-methods have also been used for monitoring contaminant movement with time using an installation of permanent electrodes and automation in the data collection system (Bevc & Morrison 1991;Blum 1989;Greenhouse & Harris 1983;Greenhouse & Monier-Williams 1985;Kaufman et al 1981;Rogers & Keen 1980;Van et al 1992). Based on the review presented here, f~-methods for monitoring may be classified into two groups: absolute resistivity measurements and relative temporal measurements.…”

A large number of landfills and waste disposal sites have been located on or in alluvial and glacial deposits. Fine-grained silts and clay layers in these alluvial deposits, or man-made liners of rolled clay, perhaps combined with a polymer sheeting, are important barriers and retardants to vertical leachate migration underneath the landfills. Ideally, these barriers prevent leachates from contaminating groundwater, and resistivity surveys are useful to study site integrity, provided a sufficient resistivity contrast exists. In this article, we introduce a different approach for resistivity monitoring of landfills, waste fluid ponds, salt storage sites, or other sites where environmental concerns exist as to the migration of materials through porous or fractured media. The method is based on the measurement of the horizontal gradient of the vertical electric field as a function of receiver distance. Numerical model responses over a hypothetical landfill model are presented to demonstrate the method. Model results show that monitoring the vertical electric field and presenting the horizontal gradient of the vertical electric field as a function of sampling distance provides good sensitivity to track the movement of an anomalous resistivity zone. The theory is complete, but the method needs to be field tested to determine operational sensitivity and repeatability.

A B S T R A C TTerminating industrial activities may have harmful side effects on the infrastructure of a civil society. One effective method of solving environmental and geotechnical problems in urban areas is a direct-current resistivity survey. In karstic areas, largescale geological structures directly affect the near-surface, small-scale events. Reliable data on the geological background of harmful events are acquired through suitable combinations of large-scale and of small-scale high-resolution surveys. In this study, the geological background of three urban subsurface-related problems was investigated in a karstic area: collapse of a sinkhole, suffusion of a basement area, and contamination of an urban creek. In each case, the scientific work aimed at setting up of a suitable model that describes the harmful event and its geological background. For this purpose, a combination of large-scale and high-resolution resistivity data was acquired and augmented by borehole information and laboratory analyses. The error analyses of the resulting models suggest that the methodology of dual-scale geoelectric investigation of urban hazards in karstic areas can provide applicable models for mitigation measures.
