Description

With regard to the smooth implementation of a recycling-based society, the issue of illegal waste dumping demands an earnest discussion of possible solutions. We present a case study of field investigations conducted at a particular illegal dumping site located in one of Japan's mountain areas. Non-destructive techniques, such as the electric resistivity survey and surface wave survey were used, along with boring investigations which allowed us to investigate the distribution of waste found in the ground. From the results of the resistivity survey, we estimated that the low-resistivity area was considered to be waste, while the high-resistivity area was considered to be natural soil. In addition, the two-dimensional distribution of waste could be understood using a combinational interpretation from data which came from the resistivity and surface wave surveys, and from the boring logging. Since field surveys need to be conducted quickly in order to diminish any interference of ongoing environmental conservation efforts at the illegal dumping site, we believe that this field surveying method, which can investigate the entire image of a site, holds great potential.
