Abstract
A soil pollution monitoring system includes a plurality of ducts for conveying gases and air past a sensing device. The sensing device detects selected compounds in the gases and air and provides an output in electrical form which indicates whether or not the levels of certain compounds in the gases and air are greater than a threshold amount thereby indicating that a leak has occurred.
