Characterization and treatability of a contaminated soil from an oil exploration zone
Abstract: A crude contaminated soil, arising from an oil production zone in Tabasco, Mexico was studied. A sample of about 40 kg was dried and screened through meshes 10-100. Total petroleum hydrocarbons and 6 metals (Cd, Cu, Cr, Ni, V and Zn) were determined to the different portions. For soil which passed mesh 10, six non-ionic, three anionic and one zwitterionic surfactant solutions (0.5%) ...

Bioremediation of petroleum contaminated Soils in Brazil Using AgroRemed
At Atuba at the corporate site of COPEL, a state owned utility company, soil was heavily contaminated with transformer oil due to a long history of contamination since 1964 probably due to unsafe practices of storage and cleanup. The level of contamination measures as TPH in soil was as high as 766,695 ppm and much of the contamination was at a depth of 1 meter. The site is located on a hill and ...

Successful In Situ Remediation of Hydrocarbon Contaminated Soils in South Africa
Location: PepsiCo Frito-Lay Simba Isando, Gauteng, South Africa Use of the vehicle workshop area at the Frito-Lay Simba Isando plant was discontinued due to outsourcing of the distribution chain. An area in front of the wash bay bordered by the workshop and boundary walls had been heavily contaminated by hydrocarbon. This contamination was a mix of petroleum (PRO) and diesel (DRO) range organics ...

Monitoring of petroleum hydrocarbon degradative potential of indigenous microorganisms in ozonated soil
This study was performed to investigate the petroleum hydrocarbon (PH) degradative potential of indigenous microorganisms in ozonated soil to better develop combined pre-ozonation/bioremediation technology. Diesel-contaminated soils were ozonated for 0–900min. PH and microbial concentrations in the soils decreased with increased ozonation time. The greatest reduction of total PH (TPH, 47.6%) and ...

Toxicity of fuel contaminated soil to antarctic moss and terrestrial algae
Fuel pollution is a significant problem in Antarctica, especially in areas where human activities occur, such as at scientific research stations. Despite this, there is little information on the effects of petroleum hydrocarbons on Antarctic terrestrial biota. This paper demonstrates that the Antarctic mosses Bryum pseudotriquetrum, Schistidium antarctici, Ceratodon purpureus and the Antarctic ...

Effect of OSE(II)-Enhanced Soil Washing(OESW) for TPH -Contaminated Soil Remediation
The objectives of this study were to perform potentially suitable active agent that solubilize total petroleum hydrocarbon (TPH) present as contaminants and to evaluate the optimal range of process parameters that can increase the removal efficiency in OSE(II)-enhanced soil washing (OESW) pilot tests. Used experimental method for solubilisation of TPH by using OSE(II) was batch experiments. The ...

Environmental and health risk assessment of an oil contaminated site in the Mexican tropical southeast
The aim of the present study was the environmental and health risk assessment of the oil contaminated soil in the Mexican tropic. The case is based on the total petroleum hydrocarbons (TPH) and polycyclic aromatic (PAH) soil contamination resulting from the activities of the oil industry over 70 years. The results of this study were estimated using CalTOX, a multimedia exposure model. The ...

Case Study - Crude oil and refinery waste
For years refinery and oil field waste had been dumped into the marsh adjacent to a large residential community. The waste oil had also started seeping into the local groundwater. The area included three large ponds including a bermed area, 3 meters deep, containing a mixture of 60% oil-tar in water. The total area held approximately 3,400 cubic meters (m3) of contaminated soil and sludge ...

Sea Power 101: Notable Case Studies
Russian Air Force Base, Eastern Germany: Land underneath this site had become contaminated over a long period of time by a mixture of lubricant oils, hydraulic fluids and aviation fuel. Following excavation, the soil was reconstituted in biopiles and applied with Sea Power 101. The vast majority of hydrocarbons were removed in the first month, and the site was fully remediated within four months. ...

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 ...

Can I extend the range of the TPH in Soil kit by dilution?
The pocket colorimeter kit by Hach offers an immunoassay method to measure TPH (Total Petroleum Hydrocarbons) in soil samples – a useful indicator of petrol pollution or contamination in soil. For areas of heavy contamination the range of the test can be extended by dilution during the soil extraction step. The first stage in the test is to extract the TPH from the soil into a liquid, ...
