Detailed Description
Television cameras commonly are used in ground-water studies to inspect the condition of well casing and screens; they also can be used to directly view (1) lithologic texture, grain size, and color; (2) water levels and cascading water; and (3) bedrock fractures. Television logs can be obtained in clear water and above the water level. The most sophisticated television systems are magnetically oriented and provide a 360-degree digital image of the borehole wall.
