Fun Facts
Fun Facts - JRW Bioremediation, LLC

It is well known that a consortium of microbes is needed for the complete degradation of PCE or TCE to ethene. Because each of these microbes may have its own nutrient requirements, a single limiting nutrient may not be applicable to heterogeneous groundwater populations. A blend of nutrients is therefore preferred (Swindoll, C.M, et all., 1988. AEM, Vol 54, p 212-217)


  • Increases the efficiency of electron donors.
  • Increases the rate of dechlorination to ethene.
  • Stimulates microbial growth and promotes the production of propionate over acetate


  • At a usage rate of 3% the fermentable fraction of your electron donor, adding Accelerite® costs pennies on the pound per total electron donor utilized

  • Store unopened under dry conditions at temperatures between 35°F and 85°F.
  • The shelf life of the unopened products is 1 year
  • Diluted products should be used within 3 days to avoid microbial growth and activity which may cause gas buildups in containers and visible growth which may foul equipment.
  • Following injection of material, wells should be flushed with clean water to prevent microbial growth.
  • Equipment decontamination should follow site-specific requirements. In most situations, any product residual should be flushed into the aquifer and then chased with clean water.
