Hydrocarbon-Contaminated Soil Remediation
Hydrocarbons are organic compounds composed of hydrogen and carbon atoms and are the building blocks of many fossil fuels. Petroleum products, such as gasoline, diesel, and oil, are major sources of hydrocarbons. Spills or leaks of these products can result in soil contamination, and if left unaddressed, can have significant environmental and health impacts. In this article, we will discuss the ...

Oil-Contaminated Soil Remediation: The Process of Cleaning Up Soil Polluted With Oil
Oil contamination of soil is a widespread problem that can have serious environmental and health impacts. The presence of oil in the soil can result from a variety of sources, including spills from storage tanks or pipelines, leakage from vehicles, and improper disposal of waste oil. In order to protect the environment and public health, it is essential to clean up contaminated soil and restore ...

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 ...

Mapua, New Zealand - Case Study
In collaboration with the New Zealand Ministry for the Environment and Tasman District Council, EDL undertook its largest project to date at the Fruitgrowers Chemical Company site in Mapua. 8,650 m3 of soil heavily contaminated with Lindane, DDT, Dieldrin, and Aldrin was treated at what was known as country’s most contaminated site. All soil was successfully remediated to levels below soil ...

Analytical model for uni–directional flow passive soil vapour extraction system
An analytical one–dimensional model has been developed to examine the uni–directional barometric pumping in passive Soil Vapour Extraction (SVE) system. The model is applicable to a special case in which a radial flow field is insignificant. The system considered contains two unsaturated zone layers, an upper contaminated low permeability layer and a lower high permeability layer contains a well ...

Guaranteed fixed price PCE remediation – site 22 naval station Great Lakes, Illinois
TRS Group, Inc. (TRS) worked as a subcontractor to Tetra Tech NUS to remediate PCE-contaminated soil in a tight silt-clay soil matrix. The remedial criteria required all PCE concentrations to be less than 20 mg/kg - a 95.5%reduction of PCE in soil to meet the Illinois EPA Tiered Approach to Corrective Action Objectives (TACO) industrial/ commercial criteria. The remedial goal was surpassed within ...

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 ...

The fate of arsenic in contaminated paddy soil with gypsum and ferrihydrite amendments
Ferrihydrite and gypsum (CaSO4·2H2O) are two chemicals which were suggested to reduce the bioavailability of arsenic (As) in agricultural field. The efficiency of those chemicals added in the paddy field was investigated by pot culture in this study. The results showed As uptake by rice under ferrihydrite treatment was significantly lower than that in the control (36% in shoot), however, plants ...

Remediation Of MTBE Contaminated Soil And Groundwater
Methyl tertiary-butyl ether (MTBE) is a fuel additive made, in part, from natural gas. Since 1979, it has been used in the United States as an octane enhancing replacement for lead, primarily in midand high-grade gasoline at concentrations as high as 8 percent (by volume). Since the mid-1980s, it has been widely used throughout the country for this purpose. It is also used as a fuel oxygenate at ...

Growth response and tolerance of Job's tears (Coix lacryma-jobi L) to arsenic in spiked soils
Job's tears (Coix lacryma-jobi L.), a perennial herbaceous plant, was cultured in soils spiked by arsenic. The results show that Job's tears rapidly grows with high biomass and strongly tolerates with normal accumulation for As in lightly or moderately spiked soils. It insensitively responds to As changes when the content of As in soils is less than 40 mg kg−1 while the concentration of As in ...

Inter‐species rootstocks affect cadmium accumulation in post‐grafting generation plants of potential Cd‐hyperaccumulator Solanum photeinocarpum
Pot and field experiments were conducted to study the effects of inter‐species rootstocks on cadmium (Cd) accumulation characteristics of potential Cd‐hyperaccumulator Solanum photeinocarpum post‐grafting generation plants. Four treatments [ungrafted (UG) and S. photeinocarpum seedlings grafted on the rootstocks of eggplant (EG), potato (PG) and tomato (TG)] were utilized in present study. In ...
