Abstract

This paper present a new concept in the design of distributed fiber-optic sensor systems for in situ monitoring of leaks in lined landfills. The concept utilizes disposable sensor that cut the fiber selectivity and thereby disclose the location of the leak. The demonstrated advantage of the sensor is simplicity and the ability to operate reliably in harsh environments. The anticipated advantages are low cost, high long-term reliability and simple installation. The novel features of the leak detection systems are that in addition to its potential for detecting leaks in situ, it can pinpoint leak location and the rate of spread. the leak detection system has two major benefits, it can lower the cost of ground water and soil sampling and it can play an important role in risk assessments of landfills and hazardous waste sites.
