This process might not work in all petroleum-contaminated aquifers, but we have proved it works where there are sulfate-reducing microbes present in the environment.
One of the major advantages of using an anaerobic technique is it lets you remove MTBE at the source, before it has a chance to spread.
We were faced with a massively contaminated site,
When we added sulfate to the aquifer, we saw virtually immediate stimulation of benzene removal. The bacteria oxidized benzene and produced carbon dioxide, which is not harmful to the environment,
