2D geoelectrical resistivity tomography application at the former city waste dump "Ada Huja": Eco-geological problem

Abstract

Rapid yearly technology development has enabled the possibility of renewing already acquisitioned data using new and improved software capabilities. The potential to gather 3D inversion results from 2D acquisitioned data is one of many new software options that were not available twenty years ago. Data obtained by ground penetrating radar (GPR) using 500 MHz and 300 MHz frequencies were used to confirm information attained by electrical resistivity tomography, hence the GPR survey was only conducted on a small portion of one profile line. Suitable location of the former communal waste site "Ada Huja" and the degree of possible environmental pollution are one of many reasons why it was crucial to reinterpret the 2D inversion data. Two decades after the initial scanning the data was used to solve the eco-geological problem which is a side effect of the decade long disposal and non-aiding of the communal waste dump.
