TersOx™ is a specially formulated calcium peroxide that produces a controlled-release of molecular oxygen designed to assist in the aerobic bioremediation of hydrocarbons in soil and groundwater.

TersOx stimulates natural degradation of petroleum hydrocarbons such as benzene, toluene, ethylbenzene and xylenes (BTEX). This is not a chemical oxidation product. The high ratio of O2 in TersOx (>16.6% by weight) provides a long-term oxygen source for up to 12 months upon hydration
under ideal conditions. This sustained release of oxygen stimulates indigenous bacteria, accelerates bioactivity, and promotes increased contaminant removal.
