Abstract: A subsurface sampling system which is designed to avoid disturbance of the sample point allows for repetitive insertion of a sampling means, such as a resin capsule, to allow repetitive sampling at a given location. Through variation in the design natural percolation and angled positioning may be accommodated. A shield and other means for diverting external substances such as ground water, rain, and the like are incorporated as well as a cap which integrates with a spring or other type of tension means to appropriately position the sampling means adjacent to the particular point desired to be sampled. A central access chamber and a variety of sampling passageways are provided for in applications in which repetitive-sampling at multiple sites is desired.
