African Male Scientist in Protective Workwear Taking Water Samples From Polluted Mountain River

A young adult squats along a rocky riverbank to collect a water sample. He wears a disposable light blue gown and a white face mask, holding a test tube. He collects the sample and holds it up to the sunlight to observe it. The river rushes by next to him, and green trees and mountains rise up in the background. This clip is well-suited for projects about science, the environment, conservation, water testing, and environmental health.
