electrical resistivity) for mapping moisture content and lithologic properties of the contaminated media
• in situ radio frequency (via horizontal wells), and ohmic heating (through vertical wells), to increase mobility of the contaminants, there-
  by speeding recovery and the remedial process
• high-energy corona destruc-
  tion of VOCs in the offgas of vapor recovery wells
• application of a Brayton cycle heat pump to regener-
  ate carbon adsorption media used to trap VOCs from the offgas of recovery wells
• in situ permeable flow sen-
  sors and the colloidal boro-
  scope to determine ground-

water flow chemical sensors (fiber-optic TCE, Halosnif, direct sampling) to rapidly quantify chlorinated solvent contamination in the subsurface
• in situ bioremediation through methane/nutrient injection to enhance de-
  gradation of contaminants by methanotrophic bacteria
