Electrical Detection And Monitoring Of Leaks In Lined Waste Disposal Ponds

Waste disposal ponds or landfills may be lined with<br>impermeable plastic liners to prevent escape of noxious or toxic<br>fluids into the environment. Verification of the integrity of the<br>liner is important, both to assure quality at time of installation<br>and to guard against damage during the life of the pond. Several<br>leak-detection techniques have been employed which exploit<br>similarities between fluid flow and electric current in such an<br>environment. In this work, I describe a method which overcomes the<br>short-comings suffered by previously described systems.
