Weston - In Situ Recirculating Well Technology
Recirculating Well Technology is an in situ system for remediating contaminated aquifers. This technology is based on a very simple concept and design where downhole equipment creates movement of groundwater into and back out of the well after treatment. This movement develops a groundwater circulation cell around a remediation well. The circulating groundwater transports contaminants in the adjacent soils and groundwater to the well, where they are removed using a combination of physical, chemical, and biological treatment processes.
Since groundwater movement and treatment occurs below ground level discharge permits normally required by other groundwater technologies are avoided.
WESTON has used In Situ Recirculating Well Technology to treat a variety of contaminants.
Several projects using this technology are currently underway in the United States.
