An earth contamination site groundwater testing well having a borehole which passes though subsurface soil zones of interest is provided with a probe assembly that is installed in the borehole, that has a core stem which carries spaced-apart flexible disc seals that divide the borehole into different borehole zones that correspond to the subsurface soil zones of interest, and that includes microporous sampler points in the different borehole zones. The groundwater testing well borehole may be formed with a well casing that is afterwards removed while retaining the probe assembly in position.

Groundwater testing well

A heating fuel comprising a combustible material which can flow when heat is applied, with a wick covering the combustible material to assist and control combustion. The fuel can be made from materials found in ordinary household waste, using newspaper for the wick and polyethylene plastic for the combustible material. The fuel can be conveniently used if made in the form of approximately cylindrical logs, but with the diameters near the ends of the logs greater than the diameter near the middle, to provide air gaps when the logs are stacked. The combustible material can be made of plastic extruded into rods and embedded in a mass of dried pulped newspaper, with the outer surface of the mass having the desired log shape.
