Abstract: A water sampling assembly which utilizes a clear container. The clear container is connected to a generally circular lip portion via a shoulder portion. The lip portion has an open distal edge and being threaded on an exterior surface. The diameter of the main body is than the diameter of the lip portion. Contained with the main body is a spherical stopper mechanism which rises as water enters the main body until such time that the spherical stopper seals the shoulder/lip portion so that further water is discouraged from entering the main body of the clear container. Ideally a cap mechanism is provided that is securable to the lip portion via threads so that the entire assembly, with the collected water sample, is easily transported and stored.
