Feasibility study of in-situ bioremediation for nitrobenzene-contaminated groundwater
Although many studies have simulated in-situ bioremediation of contaminated groundwater, most of them have not considered hydrochemical conditions and indigenous microorganisms, thus potentially rendering results inapplicable to actual in-situ groundwater bioremediation projects. This study focused on a nitrobenzene-contaminated groundwater site located in Jilin City, China. The actual ...

Common Treatment Train for Fuels
A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for fuels is illustrated below. The fuel contaminated soil is first treated using a soil washing process. Water is injected at the up stream side of the contaminated site. Surfactant or other additives may be added to enhance the soil washing effect. Contaminated water is pulled ...

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 ...

Gasoline, jet and diesel fuel soils contaminated - Petroleum product storage terminal
LOCATION: Tiverton, Rhode IslandPROJECT DATE: April, 1993 to PresentCLIENT: Confidential BACKGROUND: Soils at this 106 acre former petroleum product storage terminal have been impacted with gasoline, jet fuel, and diesel fuel over the course of 50 years. Estimates of the impacted soils range from 200,000 to 400,000 cubic yards. ACTION TAKEN: Ex-situ bioremediation is being used as the ...

Enhanced Bioremediation
Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...

Sustainable Remediation: Harnessing Bioremediation Power With Delta Remediation
What Is Sustainable Remediation? Sustainable remediation is the process of remediating polluted environments using environmentally friendly and sustainable methods. It seeks to reduce the environmental impact of cleanup processes while effectively addressing the contamination issue. Sustainable remediation also means remediation processes that end the lifecycle of the contamination rather than ...

Bioremediation: An Eco-Friendly Solution For Environmental Cleanup
Introduction Bioremediation is the use of microorganisms, or their enzymes to clean up environmental pollutants. It is a sustainable and cost-effective approach to clean up contaminated soil, water, and air. Bioremediation can be applied to a variety of pollutants, including petroleum, pesticides, and solvents. Bioremediation is a complex process that involves various biochemical reactions, ...

CH#952 - Oil Contaminated Soil
SITE OWNER: A National Overnight Express Package Company SITE SURVEY: Site and geological surveys revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was the result of two (2) underground storage tanks (UST™). One tank contained waste oil while the other contained new oil. Both tanks had been removed. A monitor well was ...

A Citizen`s Guide to Natural Attenuation
What is natural attenuation?Natural attenuation makes use of natural processes to contain the spread of contamination from chemical spills and reduce the concentration and amount of pollutants at contaminated sites. Natural attenuation—also referred to as intrinsic remediation, bioattenuation, or intrinsic bioremediation—is an in situ treatment method. This means that environmental contaminants ...

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 ...
