Leachate plumes transport toxic materials, which are hazardous to groundwater resources. The Norman landfill research site is a closed municipal solid waste landfill, formerly operated by the city of Norman, OK. Current study was conducted to map the edges of the Norman landfill leachate plume. Both geophysical and geochemical approaches had been adopted to locate the boundary of the plume. Several geophysical techniques were applied including electrical resistivity, spontaneous potential (SP), and EM 34. In addition, Total Dissolved Salt (TDS) data were provided from groundwater samples collected from wells. Our results from EM 34, Resistivity and TDS, suggest a highly conductive zone in the study area. Presence of conductive medium in the subsurface may have been caused by higher concentration of contaminants from the leachate. All the results obtained from different geophysical techniques represent significant correlation. This anomalous area of conductive zone relates to an area of higher chloride concentration, identified from TDS data. Therefore, by integrating all the results from geophysical and geochemical methods used for this study, the edge of the leachate plume was located along the central part of our survey lines. Present study suggests that an integrated geophysical approach using various tools can be successfully applied to locate conductive zones associated with contaminant leachate plume, which is farther validated by chloride concentrations from TDS data.Presentation Date: Wednesday, October 17, 2018Start Time: 9:20:00 AMLocation: Poster Station 3Presentation Type: PosterKeywords: resistivity, electromagnetics, environmental, tomography, electrical/resistivityPermalink: https://doi.org/10.1190/segam2018-2998496.1FiguresReferencesRelatedDetailsCited bySimulation Study for Hydraulic Fracture Monitoring Based on Electromagnetic Detection Technology1 February 2023 | Water, Vol. 15, No. 3Applicability of combined GPR and gradiometer to detect buried shallow targets for near-surface investigationsIftekhar Alam, William Piwonka, James Atkins, and Joseph Panzik10 August 2019 SEG Technical Program Expanded Abstracts 2018ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2018 Pages: 5520 publication data© 2018 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 27 Aug 2018 CITATION INFORMATION Md.
