Terramend® Reagent

Terramend® aerobic bioremediation reagent is a cost effective treatment technology for soils impacted by organic compounds. The Terramend technology is advantageous because it can often be applied without excavation, generates no odors or leachate, and does not result in soil bulking (1-3% soil mass application rates typical).

An independent audit conducted by the U.S. EPA concluded that the technology represented a safe, effective, and cost-efficient means of treating soils (US EPA/540/R-95/536 July, 1996).

Two Terramend formulations are available and selected based on site conditions and targeted contaminants. Terramend Carbon treats soils containing recalcitrant compounds, including polycyclic aromatic hydrocarbons (PAHs), phthalates, and chlorophenols (including pentachlorophenol). Terramend Inorganic treats biodegradable compounds, including BTEX, GRO, DRO, and TPH.

We will develop an appropriate dosing level and treatment approach for your site, based on contaminant mix, remedial goals and other site specific factors.
