ABSTRACT:
A liquid sampling apparatus for use in sampling the liquid in a well pipe to determine surface contaminants contained therein includes a unitary tubular housing formed to provide a valve seat therein. A ball, freely movable within the tube, is inserted to cooperate with the valve seat to form a valve which remains closed once the sampling tube is filled with water. The opposite end includes a retaining device onto which is affixed a flexible line that has its opposite end affixed to the removable well cap. The flexible line is used to remove the liquid sampling apparatus from the well after a sample of the liquid contained therein has been obtained.
