Fun Facts
Fun Facts - JRW Bioremediation, LLC

ChitoRem® is a complex of materials that includes calcium carbonate for buffering and organics to promote microbial growth. This unique combination of materials allows ChitoRem® to be used for the remediation of multiple types of environmental concerns including the destruction of organics in the dissolved phase to the removal of metals.


  • Provides both a fast and slow-release carbon source and nutrients.

Inherent Buffering Agent

  • Contains calcium carbonate which serves as a natural buffering agent for low pH applications.

Niche Application for Acid Mine Drainage


  • Store unopened under dry conditions at temperatures between 35°F and 85°F.
  • The shelf life of the unopened products is 2 years
  • If kept dry, opened product can be stored for 1 year
  • 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.
