Are any undesirable residuals left in the subsurface once the remediation project is complete?
A. No. Butane Biostimulation Technologies stimulate the growth of naturally occurring microbes using butane as a food source and oxygen as an electron acceptor. Once the project is complete and butane is no longer being added to the subsurface the microbes are no longer being provided with an easily metabolized food source and their numbers decrease and return to their natural levels.
