  • Treatment of contaminated groundwater
    Patent number: 5605634
    Abstract: The system places traces of nutrients and other treatment substances in the ground, in the path of an on-coming plume of contaminated groundwater. Boreholes placed across the plume contain respective diffusion tubes, the tubes being of e.g LDPE, or dialysis tubing. The remediation substance is circulated (pumped) through the diffusion tubes periodically. The remediation substance diffuses through the LDPE into the water in the borehole, and thence into the plume and is carried into the aquifer.
