Abstract : Perchlorate is an inorganic anion that consists of chlorine bonded to four oxygen atoms. It is a primary ingredient in solid rocket propellant, exhibits high solubility and mobility in water, and has been identified in groundwater at numerous sites across the United States. Enhanced in situ bioremediation (EISB) of perchlorate-affected groundwater offers the potential to treat and destroy perchlorate in the subsurface. This report describes work conducted to demonstrate/validate the use of an active EISB approach at the Western Non-Aerospace Non- Industrial (WNN) Easement of the Inactive Rancho Cordova Test Site (IRCTS) in Rancho Cordova, CA. The overall objective of this work was to demonstrate the efficacy of the active approach to EISB. The demonstration was designed to evaluate performance objectives, which are as follows: 1) Ease of installation of system components; 2) Ease of electron donor delivery events; 3) Enhancement of microbiological activity; 4) Ease of performance monitoring and validation; 5) Reduction in perchlorate concentrations; and 6) Radius of influence (ROI) and distance for degradation.
