Spolchemie site remediation and NanoRem field site application
Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the current ...

In-Situ Petroleum Bioremediation Rates With Petrox
Recent data from field applications of Petrox bioremediation show degradation rates of 100 to 500 micrograms per liter (ug/ml) per day. These degradation rates are for total petroleum hydrocarbons or total BTEX, depending on the site monitoring requirements. Achieving high degradation rates requires high initial concentrations. Initial concentrations of 1,000 to 10,000 ug/l were used to develop ...

Case study – BTEX contamination - Kentucky
In 1992, remedial activities began at the Shively Service Center located in Radcliff, Kentucky. After the leaking underground storage tanks were removed from the site approximately 1,500 cubic yards of BTEX impacted soil was excavated and disposed off-site from the tank pits. Based on the review of historical sampling activities it was believed that the majority of the impacted soils were removed ...

Fast BTEX and methylnaphthalene bioremediation
Petrox Petrox and Methylnaphthalene Bioremediation Site Summary Petrox micorbes accelerated BTEX and methylnaphthalene bioremediation at a former fueling station in Florida. After a leaking tank underground storage tank (UST) was removed Petrox micorbes were applied to the groundwater. A temporary well showed high concentrations of BTEX, methylnaphthalene isomers, and total recoverable ...

Waterloo Emitters used for Bioremediation Study in High Temperature Saline Groundwater
A study was undertaken to determine the success for aerobic bioremediation of aromatic hydrocarbons (BTEX) and MTBE (methyl tert-butyl ether) in high temperature, saline groundwater conditions. The study included laboratory microcosm experiments, as well as a field trial in Saudi Arabia, in which Solinst Waterloo Emitters were used. To view the full paper published about this study, please visit ...

Assessing the transport and fate of MTBE
Untitled Document Abstract The ether oxygenates MTBE and TAME have been used in petroleum fuel formulations in the UK since the mid-1980s and have led to contamination of major aquifers with these chemicals, including the Chalk aquifer of southern England. An assessment is made of the controls on the fate of MTBE and BTEX compounds at a contaminated site on the Chalk aquifer, ...
