Abstract:
1. A system for collecting gas from a subsurface body of contaminated water, the system comprising: a site to collect unabsorbed reactive gas from the subsurface body of contaminated water; a vacuum source connected to the site; a controller to regulate a flow of the reactive gas from the site to the vacuum source; a line to provide fluid communication between the vacuum source and the site; a boring device to generate a bore hole, wherein the line is disposed within the bore hole; and a porous device being coupled to an end of the line and disposed at the site, the porous device being configured to facilitate the intake of the unabsorbed reactive gas while substantially preventing an ingress of soil, wherein the porous device further comprises a plurality of heat bonded metal particles being coupled to the end of the line.
