Abstract
A portable apparatus and method for collecting and testing ground water samples including a container (12) defining a chamber (14) in which a control atmosphere is established. A valve means (22) is included which is capable of bypassing water away from the chamber (14) and continuously admitting water samples to the chamber (14). A preferred method of collecting a ground water sample includes the steps of establishing a controlled atmosphere in the chamber (14), directing the flow of water into the chamber (14), collecting the water sample inside the chamber (14), and testing the sample inside the chamber (14) to prevent contamination from the air on the exterior of the chamber (14).
