Fun Facts
Fun Facts - JRW Bioremediation, LLC

A form of WILCLEAR® sodium lactate has been used for years as a food preservative. If you ate pre-prepared meat or mass produced bakery goods for lunch or dinner today, those foods most likely were treated with sodium lactate to give them a longer shelf life.


  • Lactate is a proven technology and one of the most efficient electron donors available.


  • Lactate rapidly establishes anaerobic conditions needed for dechlorination.


  • Lactate provides the perfect concentration of hydrogen needed for rapid dechlorination.


  • Store unopened under dry conditions at temperatures between 35°F and 85°F.
  • The shelf life of the unopened products is 2 years
  • The opened product should be used within 30 days
  • Diluted products should be used within 5 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.
