Methane-Enhanced In Situ Bioremediation
A 1995 R&D 100 winner combines natural gas injection with air stripping to speed the degradation and removal of chlorinated solvents in groundwater and sediment. Tests have shown it to be much more efficient and cost-effective than other methods.
Other bioremediation techniques include the use of added phosphates to fuel bacterial growth and reaction rates. The PHOSter process involves adding a safe gaseous form of phosphorous to injected air, resulting in dramatic remediation rate increases.
