NAPL Occurrences at an Industrial Site: Creosote or Petroleum Hydrocarbons?

Field metabolomics and laboratory assessments of anaerobic intrinsic bioremediation of hydrocarbons at a petroleum‐contaminated site

Field metabolomics and laboratory assays were used to assess the in situ anaerobic attenuation of hydrocarbons in a contaminated aquifer underlying a former refinery. Benzene, ethylbenzene, 2-methylnaphthalene, 1,2,4- and 1,3,5-trimethylbenzene were targeted as contaminants of greatest regulatory concern (COC) whose intrinsic remediation has been previously reported. Metabolite profiles associa...

Groundwater Fate of Aromatic Hydrocarbons at Industrial Sites: a Coal Tar Site Case Study

The fate of groundwater contaminants in anthropogenic fill materials was investigated at a coal tar site, Site YYZ. This site was representative of other contaminated sites with a history of industrialization at which wastes from process operations form the local subsurface solids. The solids composing the groundwater-bearing unit at Site YYZ were reactants (oil), byproducts (tar, coke) and was...

Biodegradation of petroleum hydrocarbons in hypersaline environments

Literature on hydrocarbon degradation in extreme hypersaline media presents studies that point to a negative effect of salinity increase on hydrocarbonoclastic activity, while several others report an opposite tendency. Based on information available in the literature, we present a discussion on the reasons that justify these contrary results. Despite the fact that microbial ability to metaboli...
