TreeWell® Technology
TreeWell technology allows access to deep groundwater and bedrock aquifers, thus allowing the replacement of expensive pump-and-treat systems. Bioremediation processes in the TreeWell unit mitigate potential phytotoxic effects of underground contaminants.
How do TreeWell® units work?
• Trees operate as a pump—contaminated groundwater is drawn upward towards roots, while roots are encouraged to grow downward towards contaminated groundwater
• Root_Sleeve™ liner acts as well casing to exclude non-targeted surface water and encourage tree pumping of targeted depth
• Aeration tubing is installed to provide oxygen to root zone
• TreeWell unit acts as a bioreactor—microbes degrade contaminants before having contact with roots
• Residual contaminants treated within the tree and/or photo-oxidized within the atmosphere
Other versions of our innovative technologies
TreeWell® Technology Bio-Barrier
A barrier, similar to a typical reactive barrier, is installed to intercept the contaminant plume in the target horizon of the aquifer. TreeWell units are installed above the barrier to induce greater groundwater flow into the barrier and vertically upwards within the barrier to enhance contaminants contact with reactive media installed within the barrier. The backfill materials within the TreeWell units may also include reactive media to further reduce contaminant concentrations.
Straw TreeWell® Technology
Extracts groundwater from extreme depths. Addresses bedrock aquifers or in-situ treatment by recirculation of groundwater within the TreeWell column. Can include ZVI, EZVI, Daramend®, exchange resins, or other amendments.
