Jim Rudolph, an environmental specialist, explains the process of river water quality sampling. The video covers the use of Sekitube, a water quality sonde, and a Van Dorn sampler to collect and analyze water samples. The data collected helps identify trends and focus efforts on improving water quality by targeting specific pollutants in different river sections.

What is the primary role of Jim Rudolph in the river water quality sampling process?

• Collecting water samples
