Use of a borehole camera in a hydrologic investigation, can yield information that may
not be otherwise obtainable.

The camera permits confirmation of stratigraphy, fracture and
bedding plane separation locations, ground water inflow zones, fracture accentuation due to mine
subsidence, and other features. A borehole camera also permits viewing of well bore features
that otherwise may be unknown to exist, such as the conditions of the well bore, casing, and
pumping system, historic water levels indicated by staining or corrosion, presence or absence of
bacterial growths, existence of other organisms, the presence of foreign objects, and influx of
gases.
