Crosshole resistivity survey case study 2
Crosshole resistivity survey to search out industrial waste water This exploration survey used the crosshole resistivity technique to observe whether or not an industrial waste water plant is leaking. Chemical analyses found that this specific waste water has a low resistivity compare to normal groundwater. Our recent example shows at depth of 45m a comparatively high resistive zone fabricated ...

Comparison of dye testing and electrical leak location testing of a solid waste liner system
Abstract: Dye tracing and electrical leak location testing were independently conducted to detect and locate leaks in the primary geomembrane liner of two cells in a municipal landfill. Despite extensive quality control and quality assurance programs, water in the leak detection zone after construction indicated that the primary liner had a leak. Fluorescein dye tests were conducted by placing a ...

Tackling Non-Revenue Water by Identifying Small Leaks
Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to Non-Revenue Water, and eventually, they too can lead to ...
