Effect of water table fluctuations on petroleum contamination distribution
… the water table level at different rates on petroleum contamination distribution. The experiments were carried out using a two-dimensional sand tank model. The experimental Light Non Aqueous Phase Liquid (LNAPL) was No. 2 Diesel fuel and the experimental media was sand (Sieve 20). A known …

Degradation of tertiary butyl alcohol by a Pseudomonas sp. isolated from groundwater
… from a groundwater aquifer (50 ft. deep) at a petroleum refinery. The most probable number (MPN) of TBA degrading microorganisms was 4.9 x 10³ organisms/g (dry wt) of subsurface soil. Pristine subsurface soils, which did not have a history of petroleum contamination, had MPNs of < 2 TBA …

A bioengineered approach for sustainable crude oil pollution treatment via entrapment, dispersal and removal using Nano-CarboScavenger
Aqueous petroleum contamination continues to threaten life-dependent bodies of water and surrounding ecosystems including human habitation. It is now well established that most methods of petroleum remediation are either inefficient or involve highly toxic chemical dispersants. In this work we …

Aerobic Biodegradation of MTBE in Uncontaminated and Gasoline-Contaminated Aquifer Sediments
… in aquifer sediments containing a low level of petroleum contamination than in heavily contaminated aquifer sediments. Biodegradation of MTBE appeared to be limited by a lack of oxygen in heavily contaminated soils. When degradation was discernible it appeared to follow a first order pattern …
