What is the function of a downhole camera in groundwater investigations?

A downhole camera is specifically designed to provide a visual inspection of the interior of wells and boreholes, which is crucial for groundwater investigations. This tool allows hydrogeologists and well drillers to view the condition of the well structure, examine any obstructions or debris, and assess the geology of the surrounding formation. By capturing real-time video or high-resolution images, the downhole camera enables a detailed inspection, which can help in identifying problems such as casing failures, borehole collapse, or aquifer characteristics.

In contrast, measuring the temperature of groundwater pertains to a different type of instrumentation focused on hydrological properties, while assessing surface water quality involves sampling and testing that occurs outside the well environment. Collecting water samples from various depths also requires specific sampling equipment rather than visual inspection technology. A downhole camera distinctly supports the visual assessment aspect, making it an essential tool in groundwater investigations.
