Recycling of Crude Oil Contaminated Soil: Pyrolysis
The recycling of crude oil contaminated soil presents a formidable challenge in the realm of environmental remediation. Traditional methods often fall short in addressing the complex matrix of hydrocarbons and pollutants embedded within the soil matrix. However, pyrolysis emerges as a promising technology, offering a sustainable and efficient approach to soil remediation and resource recovery. ...

Improving the Predictability of Petroleum Brownfield Restoration
It’s no secret that the United States has an aging infrastructure problem. The public’s attention is focused on the repair of roadways and bridges, but there is also an ongoing initiative to address the existing infrastructure of legacy underground storage tanks, abandoned gas stations and truck stops, that are designated petroleum brownfields. As of July 2021, approximately 21 ...

Remediating Soil While Preserving Soil Structure
The importance of soil cannot be overstated. It’s the basis of agriculture, and as a result, is a critical component of sustaining human life. According to the EPA: “Productive soils, a favorable climate, and clean and abundant water resources are all essential for growing crops, raising livestock, and for ecosystems to continue to provide the critical provisioning services that ...

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 ...

Chlorinated Solven - ART In-well Air Stripping Technology, MN - Case Study
Accelerated Remediation Technologies, LLC (ART) was secured by a major uniform services company to provide remediation technology at a PCE site in Minneapolis. Contaminant concentrations had reached asymptotic levels and were significantly higher than defined action levels. ART worked with the client's consultant to install the ART Technology in the most contaminated source area location. Within ...

The METS Process in Brief/2019
The METS remediation process equipment is about the size of a large SUV. It is fully mobile and self-propelled. Previously excavated soil is deposited in the hopper at the top of the apparatus by a conventional front-end loader. Very large debris, such as rock, concrete or asphalt, is usually screened off at the hopper opening. From the hopper, the soil is transferred in a regulated flow to a ...

Thermally activated persulfate oxidation of NAPL chlorinated organic compounds: effect of soil composition on oxidant demand in different soil-persulfate systems
This study investigates the interaction of persulfate with soil components and chlorinated volatile organic compounds (CVOCs), using thermally activated persulfate oxidation in three soil types: high sand content; high clay content; and paddy field soil. The effect of soil composition on the available oxidant demand and CVOC removal rate was evaluated. Results suggest that the treatment ...

Electrical Resistance Heating: a Hot New Approach to Soil and Groundwater Remediation
Electrical Resistance Heating (ERH) is an aggressive remediation technology that can quickly reduce the mass of volatile organic compounds (VOCs) in soil and groundwater by over 99%. The process is often used to clean sites where other technologies have had limited success. Larger ERH sites are cleaned within 6 to 12 months and smaller sites can be cleaned in half that time or less. The ...

In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology
A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

Soil Washing
Introduction: Soil washing is a water-based process for scrubbing soils ex situ to remove contaminants. The process removes contaminants from soils in one of two ways: By dissolving or suspending them in the wash solution (which can be sustained by chemical manipulation of pH for a period of time). By concentrating them into a smaller volume of soil through particle size separation, gravity ...

In Situ Solidification/Stabilization
Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or ...

Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge
Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: in ...

Soil Fracturing
Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...
-
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. ...

Soil Vapor Extraction (In Situ)
Introduction Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. ...
