Process and system for the self-regulated remediation of groundwater

A process for the self-regulated remediation of groundwater situated beneath the surface of a contaminated ground site, said self-regulated groundwater remediation process comprising the steps of:

• selecting a ground site to be tested for potential contamination;
• extracting soil gas samples from interspersed locations within an underground soil layer disposed above the water table defined by groundwater situated beneath the surface of said selected ground site;
• gleaning information from said extracted soil gas samples to both determine the extent of any contamination and delimit any specific area of contamination at said selected ground site;
• determining both an appropriate concentration of hydrogen peroxide within a solution and an appropriate flow rate of injection according to said determined extent of contamination at said selected ground site;
• determining both an appropriate number of groundwater injection points and an appropriate spacing between said groundwater injection points according to said delimited specific area of contamination at said selected ground site;
• and
• delivering said determined hydrogen peroxide solution under pressure into said groundwater within said delimited specific area of contamination at said selected ground site via said groundwater injection points at said determined injection flow rate.

A system for the self-regulated remediation of groundwater situated beneath the surface of a contaminated ground site, said self-regulated groundwater remediation system comprising:

• a plurality of monitoring wells installed interspersedly at a selected ground site to be tested for potential contamination, each said monitoring well thereby providing fluid communication between the surface of said selected ground site, groundwater situated beneath said surface of said selected ground site, and an underground soil layer disposed above the surface level of said groundwater;
• a matching plurality of vacuum pumps in fluid communication with the surface openings of said monitoring wells at said selected ground site;
• a matching plurality of soil gas meters in fluid communication with said surface openings of said monitoring wells at said selected ground site;
• a first tank for containing a substantially inert gas under pressure;
• a second tank for containing a preselected oxygen-releasing agent;
• a pressure regulator interposed between said first tank and said second tank for providing pressure-regulated fluid communication between said first tank and said second tank;
• and
• a multiplicity of groundwater injection points in fluid communication with said second tank and spaced apart within said groundwater within a delimited specific area of contamination at said selected ground site.
