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 from rock. Below this depth is a middle resistive zone with some low resistance bands visible; this zone is suspicious to be a leaking point or fracture zone.
A borehole was drilled, impure water was found at the depth of 52m. The inversion image provided shows consistency between every adjacent cross-hole is additionally evident.
