When a new contaminant of concern (COC) is identified at a site, traditional pump-and-treat (P&T) systems often require costly retrofits.

For example, if 1,4-Dioxane is discovered, it typically requires advanced oxidation processes (AOP) — often UV-based oxidation systems — to achieve treatment. These upgrades can involve significant capital expense, operational complexity, and downtime.

TreeWell® Systems offer a fundamentally different approach.

Rather than retrofitting engineered treatment trains, TreeWell® Systems rely on dynamic, biologically driven processes. As site conditions evolve, the subsurface microbiome adapts — developing the microbial communities necessary to respond to new contaminants.

No additional mechanical systems.
No new oxidation units.
No costly system overhaul.

Just a nature-based system that adjusts and strengthens over time — delivering resilient treatment without the retrofit burden.

In several applications, implementation of a TreeWell® System has enabled transition away from active pump-and-treat infrastructure, substantially reducing ongoing operations and maintenance costs.
