ABSTRACT:
A ground water sampling device includes an elongated cylindrical integral hollow housing with an inner surface defining an inner bore. The housing has an opening on its lower end and the upper end of the housing is adapted to be attached to a probe rod string. The bore has a primary diameter section and a reduced diameter section. The reduced diameter section is formed adjacent the lower end of the housing. The inner surface of the housing has a shoulder positioned at a location where the primary diameter section transitions to the reduced diameter section. An elongated hollow screen is telescopically received within the housing and is capable of being placed in a stowed position completely within the housing during driving of the device into the ground and in a deployed position where it extends out of the lower end of the housing to collect ground water. The screen has a ridge formed adjacent its upper end which engages the shoulder of the housing when the screen is in its deployed position to prevent further downward movement of the screen. An expendable drive point is positioned in the opening during driving of the device into the ground. The drive point is disengaged from the opening prior to the screen being deployed.
