Microbial Degradation of Petroleum Hydrocarbon Contaminants: An Overview
Introduction Petroleum-based products are the major source of energy for industry and daily life. Leaks and accidental spills occur regularly during the exploration, production, refining, transport, and storage of petroleum and petroleum products. The amount of natural crude oil seepage was estimated to be 600,000 metric tons per year with a range of uncertainty of 200,000 metric tons per year ...

Screening level modeling of long-term impact of petroleum hydrocarbon contamination on fresh groundwater lenses in the Arabian Gulf region
The Gulf War in 1991 created an environmental catastrophe, one of the major consequences of which was setting several oil wells on fire in the Arabian Gulf area. The total oil spilled as a result of the damaged wells was about 3.5 × 106 m3. Out of these, 3.3 × 106 m3 of oil was recovered and exported. The rest was left behind as it was not economical to collect. The oil left behind was subject to ...

Surfactant–enhanced remediation of soils contaminated with petroleum hydrocarbons
An experimental programme was undertaken to reclaim the soils contaminated with petroleum hydrocarbons. Two types of locally available soils, clay with low compressibility and poorly graded sand, were chosen for the study. Both the soils were contaminated with varying percentages of used engine oil and gasoline. Anionic surfactant Sodium Dodecyl Sulphate (SDS) was used to reclaim the contaminated ...

Surfactant enhanced aquifer remediation (SEAR) using Ivey-sol surfactant technology
This paper will focus on the application of Ivey-sol non-ionic surfactant technology to improve the in-situ remediation of petroleum hydrocarbon contamination is soil and bedrock aquifers. Normally hydrophobic organic chemicals (HOC) exhibit limited solubility in groundwater as the contaminants tend to partition onto the soil and bedrock matrix. This partitioning can account for as much as ...
