Surfactant enhanced aquifer remediation (SEAR) using Ivey-sol surfactant technology
This paper will focus on the application of Ivey-sol non-ionic surfactant technology to improve the in-situ remediation of petroleum hydrocarbon contamination is soil and bedrock aquifers. Normally hydrophobic organic chemicals (HOC) exhibit limited solubility in groundwater as the contaminants tend to partition onto the soil and bedrock matrix. This partitioning can account for as much as ...

Remediation of silty-clay hydrocarbon contaminated site using Ivey-sol selective phase transfer technology
Earlier this year, Ivey International Inc. secured its first remediation project in Alberta using its Ivey-sol Selective Phase Transfer Technology (SPTT). This patented technology is being used to treat extensive soil and groundwater contamination at an active service station in Red Deer, Alberta. With a residential area nearby, the environmental sensitivity is relatively high. Unfortunately, ...

In Situ Chemical Oxidation Remediation Pilot Study Of A Karst Bedrock Aquifer Contaminated With Chlorinated Solvents
ABSTRACT A pilot study to evaluate an innovative in situ treatment technology was implemented at Letterkenny Army Depot, Chambersburg, Pennsylvania, for a limestone bedrock aquifer contaminated with chlorinated solvents. This technology destroys VOCs in groundwater, utilizing a network of injection points to deliver a solution of hydrogen peroxide (50%), catalysts, and surfactants. The ...

Domestic wastewater treatment with a decentralized, simple technology biomass concentrator reactor
A new type of membrane-like aerobic reactor initially designed for the degradation of hydrocarbon-derived groundwater contaminants was tested for treating domestic wastewater. The biomass concentrator reactor (BCR) consists of an enclosed, aerated tank containing a graded filtration medium with the function of solids separation, and was previously used to treat industrial wastewaters ...

Presumptive Remedies
A presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site. EPA is establishing presumptive remedies to accelerate site-specific analysis of remedies by focusing the feasibility study efforts. EPA expects that a presumptive remedy, when available, will be used for all CERCLA sites except under ...

Sustainability of decentralized wastewater treatment technologies
In many Countries, small communities are required to treat wastewater discharges to increasing standards of lesser environmental impacts, but must achieve that goal at locally sustainable costs. While biological membrane treatment (membrane bio-reactors (MBRs)) is quickly becoming the industry standard for centralized wastewater treatment plants, and would also be ideally suited also for ...

PRP: The Proven Solution for Cleaning Up Oil Spills
Originally published in 2006 at https://spinoff.nasa.gov/Spinoff2006/er_1.html Originating Technology/NASA Contribution The Exxon Valdez, an oil tanker exporting millions of gallons of oil, ran aground just after midnight on March 24, 1989 in Alaska, creating what is, to this day, the worst environmental disaster in American history. The affected area of coastal Alaska continues to feel the ...

Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate
It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate
The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

Ex Situ Biological Treatment for Soil, Sediment, and Sludge
The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...
