Providing sustainable, effective remedial solutions for complex soil and groundwater contamination since 1993
Nature-based solutions in even the most challenging conditions.
TreeWell® technology provides solutions
Our patented TreeWell® Systems offer a cost-effective, nature-based, sustainable remediation alternative that can provide hydraulic control and contaminant mass reduction. Our technology allows access to deep groundwater and bedrock aquifers, and our methods promote in-situ microbial degradation of subsurface contaminants.
-
Our TreeWell systems can treat groundwater well beyond the shallow depths reached by traditional phytoremediation methods. With our systems, we have remediated groundwater at over 100 ft bgs.
-
Our systems are designed to direct root growth and for trees to consume water from specific lithologic intervals, even those underlying zones of clean groundwater.
-
With our patented technologies and methods, we have developed in situ, plant-based solutions effective even in circumstances generally considered phytotoxic. We have planted trees in a DNAPL area with concentrations greater than 65-ppm.
-
Our systems have been installed to provide hydraulic capture, effectively replacing aging and inefficient mechanical pump and treat systems. We have success achieving remedial objectives and receiving regulatory closure.
Contaminants successfully treated by TreeWell® Systems
• Volatile Organic Compounds (VOCs) • Semi-Volatile Organic Compounds (SVOCs) including 1,4-dioxane • Pesticides • Agricultural inorganics such as nitrate & ammonium • Tritium • Solubilized metals: lead, arsenic, boron, zinc, cadmium

Our Services
Site evaluation, remedial design, phytoremediation implementation, monitoring and maintenance, and our PHYTO-INTEGRATED® approach, which includes the coordination of combined remediation strategies that incorporate our TreeWell-based engineered phytoremediation systems with other non-phyto remedial technologies
