A Low-Cost, Passive Approach for Bacterial Growth and Distribution for Large-Scale Implementation of Bioaugmentation

Abstract

The overall objective of this work is to compare the cost and performance of full-scale bioaugmentation of chlorinated solvent contaminated groundwater using passive and active bacterial distribution approaches. The relative pros and cons of active recirculation and passive inject-and-drift strategies for large-scale bioaugmentation of chlorinated solvents in groundwater were evaluated in a side-by-side comparison at the Seal Beach Naval Weapons Station (NAVWPNSTA) Seal Beach Site 70 in the City of Seal Beach, CA. Three phases of activities were completed for each of the treatment cells, as follows: Phase 1 Pre-demonstration Laboratory investigations, Phase 2 Tracer test, baseline sampling, and preconditioning, and Phase 3 Bioaugmentation and monitoring.
