Microbiologically Enhanced Vertical Groundwater Circulation Well
Microbiologically enhanced vertical groundwater circulation well (mGCW) technology significantly modifies
conventional GCW systems to effect the removal of inorganic constituents (e.g., heavy metals and nitrate)
and/or accelerate the biodegradation of persistent organic compounds under aerobic (e.g., high-molecular-weight
PAHs) or anaerobic (e.g., organic explosives, perchlorate, chlorinated hydrocarbons) conditions. The mGCW systems
are specifically designed and uniquely configured to provide accelerated aerobic, enhanced anaerobic or sequential
anaerobic/aerobic reactions. These reactions facilitate terminal destruction of persistent organics, appropriately
coupled with the removal of inorganic constituents where needed.
mGCW technology can simultaneously provide in situ treatment of soil (vadose zone) and the saturated zone
without removing groundwater.
