Editing Bioaugmentation (section)

===Petroleum cleanup===
In the [[petroleum industry]], there is a large problem with how oilfield drilling pit is disposed of. Many used to simply place dirt over the pit, but it is far more productive and economically beneficial to use bioaugmentation. With the use of advanced microbes, drilling companies can actually treat the problem in the oilfield pit instead of transferring the waste around. Specifically, [[polycyclic aromatic hydrocarbons]] can be metabolized by some bacteria, which significantly reduces environmental damage from drilling activities.<ref>{{cite web|first1=Alex|last1=Fanelli|title=Bioaugmentation|url=http://www.soil-bio-remediation.com/products/|publisher=Soil Bioremediation|date=2016|access-date=26 December 2017}}</ref> Given suitable environmental conditions, microbes are placed in the oilpit to break down hydrocarbons and alongside are other nutrients. Before treatment there was a [[total petroleum hydrocarbon]] (TPH) level of 44,880 [[parts per million|ppm]], which within just 47 days the TPH was lowered to a level of 10,000 ppm to 6,486 ppm.<ref>Barber, T.
