Contamination of subsurface soil attributable to indiscriminate land disposal of various industrial wastes is becoming a challenging problem. To counter this, engineered containment and barrier systems are used. However, to evaluate the performance of these systems, continuous monitoring to detect the presence of contaminants is essential. This necessitates development of a contaminant detector that would be useful for detecting contaminants in the soil mass in their Cl- form. With this in view, a soil contaminant detector has been developed and its testing methodology is presented in this paper. The measurements from the detector are compared with those of the argentometric method. An excellent agreement between the two results indicates efficient functioning of the soil contaminant detector.
