PROBLEM TO BE SOLVED: To obtain ground water sampling equipment capable of being used in the deep depth and sampling ground water in a direct in-site from a stratum without causing any disturbance by boring work. SOLUTION: The ground water sampling equipment is equipped with a water sampling container 11 and a plug 21. The plug 21 is provided by projecting it to the downward direction of the water sampling container 11, and it has a water sampling port 22 and a conduit pipe section 25. An inside opening 32 connected to the water sampling port 22 and placed in the upper part of the inside of the water sampling container 11 is provided to the inside of the water sampling container 11. A lift pumping pipe having a lift pumping port 42 located on the lower part of the inside of the water sampling container 11 and a lift pumping means by pressurization are included. Further, a horizontal sectional area of the plug 21 is smaller in comparison with a horizontal sectional area of the water sampling container 11. COPYRIGHT: (C)2007,JPO&INPIT
