Cost and Performance Report; In-Situ Remediation of MTBE Contaminated Aquifers Using Propane Biosparging
Abstract
The objective of this ESTCP-funded project was to demonstrate application of propane biosparging (biostimulation) for in situ remediation of MTBE-contaminated aquifers. The primary objectives of this ESTCP-funded project were: 1) to demonstrate the safe application of propane biosparging (i.e., biostimulation) for in situ remediation of MTBE; and 2) evaluate the ability of propane biosparging to reduce MTBE concentrations in a contaminated aquifers to below California Department of Health Services regulatory limit of 5 microg/L. To meet this objective, several secondary objectives were identified as follows: 1) perform microcosm testing to evaluate the ability of indigenous propane oxidizing bacteria and/or other microorganisms to degrade MTBE; 2)select and characterize a field demonstration site; 3) use field characterization and microcosm study data to design, construct and operate a field demonstration system; 4) evaluate performance of the treatment system during a 10-month treatment period; and 5) evaluate the cost of applying the technology at full scale. The project compared MTBE biodegradation in a Test Plot that was amended with propane oxidizing bacteria and treated with oxygen and propane to a Control Plot that received only oxygen. The technology also was evaluated under the USEPA SITE Program, as part of the USEPA's MTBE Treatment Technology Verification Program.
