Appeal No. 96-2058
Application No. 08/147,090
This is a decision on an appeal from the final rejection
of claims 1, 2 and 4 through 31 which are all of the claims
remaining in the application.
The subject matter on appeal relates to a method for
removing hydrocarbon contaminants from ground water and/or
wastewater comprising the steps of subjecting the surface area
of the groundwater and/or wastewater to at least a partial
vacuum, introducing a purge gas so that the gas will form a
large volume of small bubbles serving to remove the
hydrocarbon contaminants from the groundwater and/or
wastewater as they travel upward to the surface area of the
groundwater and/or wastewater, and removing the contaminated
gases from the surface area of the groundwater and/or
wastewater. This appealed subject matter is adequately
illustrated by representative independent claim 1 which reads
as follows:
1. A method for removing hydrocarbon contaminants from
ground water and/or wastewater comprising the steps of:
subjecting the surface area of said groundwater and/or
wastewater to at least a partial vacuum;
providing in said groundwater and/or wastewater a
plurality of conduits, each of said conduits having a distal
end and a proximal end, wherein the distal ends are submerged
