This specially formulated product has a molecular structure (patent applied for) which time-releases a combination of lactic acid and fatty acids. This structure (Figure 1.) allows for a continuum in the release profile providing an immediate, medium range and long term, controlled-release supply of hydrogen to fuel the natural, reductive dechlorination process.

Reductive dechlorination (Figure 2.) results in the step-by-step biological degradation of chlorinated contaminants. HRC Advanced can be used to degrade a range of chlorinated compounds including: degreasing agents (PCE, TCE, TCA and their breakdown products), carbon tetrachloride, chloroform, methylene chloride, certain pesticides/herbicides, perchlorate, nitrate, nitroaromatic explosives and dyes, chlorofluorocarbons, certain metals and radionuclides.

HRC Advanced is supplied and shipped as a liquid concentrate. It can be applied to the subsurface via direct-injection in either its delivered, concentrate form or in an emulsified, high-volume form (recommended). The emulsified, high-volume material offers a unique micro-emulsion/ micelle suspension (refer to HRC Advanced Tech Bulletin 2.0 for more on micelles) which maximizes subsurface distribution by impacting a large volume of the targeted aquifer pore space immediately upon injection. HRC Advanced enhances transport in the subsurface through micelle formation and the release of soluble lactate fractions affecting an increasing volume of aquifer over time with a single injection.
