Bioremediation
Injection:
HRC
(Hydrogen Releasing Compound):
HRC is an environmentally safe polylactate ester that slowly releases
lactic acid upon hydration.
The HRC is
applied to the subsurface with push-point injection or
within
dedicated wells.
The HRC is then
left in place where it works to stimulate rapid contaminant degradation
as anaerobic microbes metabolize the lactic
acid. This produces low concentrations of dissolved
hydrogen
that is then used by other subsurface microbes to
strip the solvent molecules of their chlorine atoms and allow for
further biological degradation. When in the subsurface, HRC continues
to operate for a period of
a
year’s time, cost effectively degrading chlorinated ground
pollutants such as
PCE, TCE, and TCA.
 By
providing a long-lasting, time-released hydrogen source, HRC cost
effectively degrades chlorinated solvent contamination in place, at a
fraction of the cost of other treatment technologies.
ORC
(Oxygen Releasing Compound):
ORC is a patented formulation of magnesium peroxide that causes a slow
and sustained release of oxygen when in contact with soil
moisture or groundwater. Widespread naturally occurring micro-organisms
that aerobically degrade pollutants thrive in the oxygen-enriched
environment produced by ORC. When in the presence of ORC these microbes
rapidly degrade groundwater pollutants into harmless by-products such
as carbon dioxide and water.
Thus, the
application of ORC is an excellent technique used to accelerate the
natural degradation of pollutants in groundwater 10X to 100X over
un-amended approaches.
