September 12th, 2014, Los Angeles California: SiREM’s KB-1® and KB-1® Plus bioaugmentation cultures were approved under a general Waste Discharge Requirement (WDR) by the Los Angeles Regional Water Quality Control Board (LARWQCB).

The SiREM cultures are now included on the LARWCB List of Authorized Injection Material Amendments under Bioaugmentation Organisms.This regulatory green light includes KB-1® and KB-1® Plus cultures used for chlorinated solvent bioremediation of groundwater in the greater Los Angeles region. The cultures are used specifically for bioremediation of chlorinated ethenes, ethanes and methanes.

California’s water boards make critical water quality decisions including setting standards, issuing permits (WDR’s) and determining compliance and enforcement. The LARWCB is responsible for Region 4 which includes Los Angeles and Ventura Counties plus portions of Kern and Santa Barbara Counties.

General WDRs remove the requirement for a project specific WDR and reduce the time and expense required for regulatory approval. This WDR builds on successful regulatory approvals and applications of KB-1® and KB-1® Plus in North America, Europe, Asia, Australia and Africa. KB-1® and KB-1® Plus have been applied widely in California including previous authorized applications in the greater L.A. region prior to the general WDR approval.
