Title of Listing: | | GW Contaminant Treatment/Removal with Double Well-Screen |
Category: | | Treatment Technologies |
Subcategory: | * | Air, All Listings |
Media: | | Groundwater |
Contaminants: | | BTEX, VOCs, chlorinated solvents, SVOCs, PAHs, heavy metals |

Technology Description: | |
An in situ, double-screened groundwater well that simultaneously mobilizes and removes contaminants from the vadose zone, capillary fringe, and saturated zone without removing groundwater or discharging a wastewater stream. Treatment is achieved by vacuum extraction through the upper screen, and soil flushing, air stripping, and bioremediation in the lower screen. |
| | |
Performance Status/
Limitations: | |
Confined aquifer modification or confined and low permeability vadose zone sites;
- Well retrofit to convert existing groundwater extraction wells;
- Single pass systems achieve cleanup standards in a single treatment cycle;
- Reverse flow design to inject treated water below contaminant plume;
- Free product removal wells to allow aeration of contaminated groundwater while removing floating hydrocarbon fuels;
- Immobilization of inorganic compounds for capping or disposal.
