Air sparge system - Case Study
ERC was contracted to install an air sparge system in Central Ohio. Air sparging is an in situ remedial technology that reduces concentrations of volatile constituents in petroleum hydrocarbons adsorbed to soils and dissolved in groundwater. This involves the injection of contaminant-free air into the subsurface saturated zone, enabling a phase transfer of hydrocarbons from a dissolved state to a ...

Insitu Cleanup in Less than 5 Months
The owner of the property obtained pricing to clean up the property from several environmental companies and the cost was approximately $230,000.00 for a typical air sparge, vapor recovery system. The time frame for cleanup was approximately 3 years with no guarantee that the site would ever clean up or the cleanup costs would not increase. Bioworld/Southeast priced the cleanup for the same ...

Common Treatment Train for Nonhalogenated VOCs
A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for nonhalogenated VOCs is illustrated below. A soil vapor extraction system is used to pull VOC vapor from the contaminated soil. An air sparging system delivers air below the water table to enhance bioremediation. After passing through a liquid/vapor separator, the VOC ...

Introduction to Ozone Injection Technology
Untitled Document Ozone is a highly reactive chemical that has proven to be effective in destroying a wide variety of organic chemicals, including MtBE and chlorinated VOCs. Ozone destroys organic chemicals through the process of chemical oxidation, which breaks the targeted organic chemical down into carbon dioxide and water. Ozone is commonly used in aboveground ...

How to Remediate under an Intersection with Horizontal Wells
Roadway intersections within urban settings are arguably some of the most challenging areas for subsurface remediation. Many consultants tasked with remediation of challenging sites such as these become frustrated by the inability of a vertical remediation system to influence the area of concern and/or they are anxious that they will not efficiently bring their clients’ sites to closure. ...

Common Treatment Technologies for Nonhalogenated VOCs
Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because 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, the presumptive remedy approach will accelerate site-specific ...

Reconsidering horizontal to vertical well ratios for site clean-up
Directional drilling has been used for a variety of purposes; utilities, dewatering, and remedial activities. Cutting costs for remedial activities it is always of consideration. What the costs are to clean-up a site via traditional vertical extraction wells versus using a horizontal well system needs to be reconsidered based upon todays remedial challenges. Traditionally, it has been stated that ...

Soil and Ground Water Remediation Case Study
On this State Funded Clean-Up project, Global was the project engineer and was responsible for the design of an air sparging/soil vapor extraction remediation system. The system included five soil vapor extraction wells and twelve sparging wells that operated on a rotating schedule. One of the soil vapor extraction wells and nine of the sparging wells were installed as horizontal wells beneath ...

Raynesway resource park - Case Study
The Raynesway Resource Park is a 35 hectare site bounded on three sides by the River Derwent. The southern half of a former chemicals plant, soils and groundwaters were impacted by chlorinated solvents, acid tars, hydrocarbons and ammoniacal sludges. Celtic designed a sophisticated groundwater treatment system, integrating air sparging, multi-phase extraction and chemical oxidation to address ...

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 ...

Treatment Options for Molten Sulfur Storage
Documento sin título Molten sulfur is present in an ever widening presence in many industries. Besides the traditional sources of sulfur, such as refineries and natural gas plants, and the well known users of sulfur, such as sulfuric acid plants and fertilizer production, sulfur has become a common feedstock in more conventional chemical production such as tire and rubber ...
