Evaluation of a Novel Multiple Primary Substrate (MPS) Cometabolic Approach for In Situ Bioremediation of 1,4-Dioxane and Chlorinated Solvents in Groundwater
Abstract
The key objective of this ESTCP project was to utilize aerobic cometabolism to treat both 1,4-D and CVOCs in groundwater at North Island Naval Air Station, Operable Unit 11. During this demonstration, two gaseous compounds were used as primary substrates for specific groups of cometabolic microorganisms with different abilities to degrade 1,4-D and CVOCs in the impacted aquifer. An off-the-grid, solar powered hybrid treatment system to distribute oxygen gas, two substrate gases (methane and isobutane), inorganic nutrients, and bioaugmentation cultures isolated from the site (ENV493 and ENV494M) was designed, constructed, and operated for tilde17 months.
