In Situ Soil Remediation: An Essential Tool For Environmental Restoration
Introduction To In Situ Soil Remediation In situ soil remediation is a critical method used to address soil contamination, playing a pivotal role in environmental restoration. This technique treats polluted soil in its original location, without needing to remove or transport the contaminated materials. The benefits of this approach are numerous, including reduced costs, minimized environmental ...

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 ...

In Situ Soil and Ground Water Bioremediation Using CL-Out Cometabolism for PCE and TCE Removal - Case Study
Background The dry cleaning solvent was found in an area around a dry cleaning machine. The solvent entered the soil below the building and percolated through the soil to a perched ground water zone and an underlying second ground water zone. The soil and sediments are interbedded alluvial and marine sediments with a high permeability. The site was close to the beach, and ground water is ...

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 ...

Multiparameter sonde used in combined remedy approach and saves $200,000 in potential costs - Case Study
A former dry-cleaning site in the Pacific Northwest, Ultra Custom Care Cleaners, was found to be contaminated with PCE (perchloroethylene). According to the U.S. Geological Survey (USGS), PCE was widely used in the dry cleaning of fabrics since the 1940s. PCE is one of the most frequently detected VOCs (volatile organic carbons) in groundwater at a national scale (Moran 2004). PCE is highly ...

Bioremediation of Oil-Contaminated Soil in Kazakhstan - Case Study
Project Description The project consisted of the bioremediation of soil contaminated with mineral oils and approximately 3% crude oil. The soil matrix consisted of a fine grain composition with high salt contents. Therefore, a special bioremediation process employing static regeneration had been developed. The remediation procedure also included the sensor assisted addition of air and steam ...

Mobilization assessment and possibility of increased availability of PAHs in contaminated soil using column tests
Surfactants are well known to increase solubility/mobility of hydrocarbons and can be used to remediate contaminated water and soil. We wanted to explore if Ivey sol R 106 used at less than the critical micelle concentration (CMC) could effectively mobilize PAH (polycyclic aromatic hydrocarbons) from contaminated soil. The first step was to establish a measurement technique. Hence, a column ...

Microfiltration of vinasse: sustainable strategy to improve its nutritive potential
The purpose of this article was to evaluate and establish microfiltration (MF) operating conditions for vinasse (ethanol industries wastewater also known as stillage, slop, distillery effluent or dunder) concentration aiming to improve the use of its nutritive potential. The operating conditions influence permeate flux that has been evaluated by monitoring the flow rate profile during the ...

Former Dry Cleaning Site Contaminated with PCE - Case Study
In-Situ® Inc. TROLL® 9500 Multiparameter Sonde helps resolve treatment challenges and saves $200,000 in drilling, reagents, and consulting. A former dry-cleaning site in the Pacific Northwest, Ultra Custom Care Cleaners, was found to be contaminated with PCE (perchloroethylene). According to the U.S. Geological Survey (USGS), PCE was widely used in the dry cleaning of fabrics since the ...

Bioremediation With The Activated Peat Moss Product In A Savanna Soil Affected By Spilled Petroleum
The preservation of environment is fundamental in order to get a self sustainable development, by keeping a harmonic relationship between oil exploration and environmental equilibrium. This is a necessary condition in order to share the oil production with other economic activities like agriculture and cattle production. In reality, the oil production is the most important factor in the national ...

In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating
An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been used in a broad range of products including but ...

Biodegradation of fenpropathrin by a novel Rhodopseudomonas sp. strain PSB07-8
The aim of our study was to isolate a fenpropathrin-degrading bacterial strain and to determine its effectiveness in bioremediating fenpropathrin-contaminated soil in the laboratory. We isolated a bacterial strain from soils and named it as PSB07-8, and showed that this organism was able to degrade pyrethroid pesticide fenpropathrin. The organism was identified as a strain of Rhodopseudomonas ...

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 ...

Spill Cleanup of Fuel Contaminated Soils After Roadway Accidents Using In Situ Bioremediation
Two case studies are presented in this paper, one study demonstrating revitalization of roadside vegetation through bioremediation after a spill of motor oil and in another case application of AgroRemed to sites affected by diesel spill with underlying utility cables. The TPH of the soil after bioremediation was reduced by more than 95% from 65,000 ppm in the first case while in the second case, ...

CL-Out In Situ Bioremediation of Perchlorate
CL-Out is a consortium of facultative aerobic organisms that are well know for their ability to utilize nitrates. CL-Out is generally used for the aerobic cometabolism of PCE and other chlorinated solvents. As the half-reaction for perchlorate is close to that of nitrate, CL-Out cometabolism of perchlorate was successfully tested in the laboratory. In addition to laboratory tests, CL-Out was ...
