### Abstract

This paper presents a case study in which the<br>Resistivity method was used at a site known as<br>Cidade dos Meninos, in the Municipality of Duque de<br>Caxias, Rio de Janeiro, where the subsoil was<br>contaminated by an organochlorine pesticide called<br>HCH – Hexaclorocyclehexane, and by metabolites. A<br>comparison between preliminary evaluation of this<br>method and the Ground Penetrating Radar (GPR) has<br>been presented elsewhere (Grazinoli et al., 1999). The<br>contamination occurred by the disposal of a great<br>quantity of HCH directly above the soil, without any<br>protection. The Resistivity survey was carried out in<br>order to help the determination of the site<br>stratigraphy, and the detection of contamination<br>processes that were taking place. Detailed geological<br>and hydrogeological informations, as well as Ground<br>Penetrating Radar (GPR) data were used to help the<br>interpretation (Barreto, 1998; Grazinoli, 1997).
