ABSTRACT:
A liquid sampling apparatus for use in sampling the liquid in a well pipe to determine the surface contaminants contained therein includes an elongated hollow housing for insertion into the well pipe which is adapted to be lowered into the well by means of a flexible line affixed thereto. The other end of the flexible line is affixed to the removable well cap. Disposed above the lower edge of the hollow housing is a valve which includes a cup-shaped closure adapted to cooperate with and seal an opening provided in the bottom thereof by means of the weight of the liquid trapped in the sampling apparatus as it is lifted out of the well pipe.
