Abstract
A simplified system and method for lining a borehole in the Earth's surface. The liner has a tubing sleeve disposed upon the interior liner wall surrounding and defining the liner's interior volume when the liner is installed within a borehole. This compact and relatively lightweight system simplifies the modes and methods of subsurface installation. Each of at least one tubing sleeve preferably contains and holds at least one slender sample tubes for transporting borehole sample water (or water pressure change data) from a liner sampling spacer to above the ground's surface. The method is a relatively inexpensive, and allows for the sealing of a borehole to define various different sampling intervals with an external spacer at each liner port, and to use tubing directly to the surface from each port, to perform various subsurface sampling and monitoring functions.
