When the geomembrane pond is too deep to navigate by wading, the use of a Leak Location Survey remote towed probe is incorporated into the survey. The ASW technicians will position themselves within the temporary survey grids on the side slopes and will pull the remote Leak Location Survey probe back and forth traversing the bottom of the pond within the survey grids. Leak size and location sensitivities are a function of soil, sludge cover, debris such as tires, sandbags and drums.
