Green remediation

The US Environmental Protection Agency’s (EPA) strategic plan calls for increased research and application of sustainable systems that promote environmental stewardship, reduce greenhouse gas (GHG) emissions, and improve energy efficiency. One area of this research is green remediation. Green remediation is a relatively new approach to environmental cleanup; expanded from the traditional ...

The Progression of Remediation

Environmental remediation involves the cleanup of contaminated ground water and/or soils impacted by a variety of contaminates. The predominate contaminates over the years have been petroleum hydrocarbons from leaking underground storage tanks and surface spills, as well as solvents and other volatile organic compounds (VOCs) from industrial processes. Today, the most effective, practical, and ...

Horizontal Directional Drilling - A Green and Sustainable Remediation Remedy

Interest in using sustainable practices and technologies for environmental cleanup has increased notably within the past few years. The US EPA and many states have published recommended practices to reduce the environmental footprint of cleanup operations, and many consultants and contractors are attempting to “go green” in contaminated site remediation. It makes sense to conserve ...

Enhanced Bio-Remediation of Wastewater

Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

Groundwater remediation pump and treat carberry, Manitoba case study

Executive Summary Two of four underground gasoline tanks were removed from an old service station located in Carberry, Manitoba a number of years after the facility ceased operating. Two tanks were left on site and were used until 1985, when Manitoba Environment was notified that a domestic well in the vicinity of the abandoned site was contaminated with gasoline. The remaining tanks were ...

Green remediation best management practices: pump and treat technologies

Overview Pump and treat (P&T) technology typically is selected in a cleanup remedy to hydraulically contain contamination and/or restore an aquifer to beneficial use. Opportunities to reduce the energy and environmental footprint of a P&T remedy, which are available during site characterization and the remedy selection, design, construction, and operation phases, rely on effective planning and ...

Pump-and-Treat Ground-Water Remediation - A Guide for Decision Makers and Practitioners

Pump-and-treat is one of the most widely used ground-water remediation technologies. Conventional pump-and-treat methods involve pumping contaminated water to the surface for treatment. This guide, however, uses the term pump and treat in a broad sense to include any system where withdrawal from or injection into ground water is part of a remediation strategy. Variations and enhancements of ...

Filter bed remediation - Case Study

Biological filter beds usually consist of a mineral media over which effluent to be treated percolates. The media becomes host to a biomass which is grazed by a series of more complex organisms. If the growth of the biomass is greater than the rate at which the grazing occurs then the biomass film will accumulate in the bed. This will block the interstices of the media and restrict effluent ...

TCE/Fractured Bedrock Remediation in VA

Site Summary At a manufacturing facility HRC was injected into a crystalline bedrock aquifer contaminated with TCE and its daughter products. Groundwater flow at this site is controlled by fractures in the crystalline rock with little or no permeability present beyond these fractures. The industrial facility had been in operation for over 30 years. Contamination levels reached 220 ppb of TCE so ...

Perchlorate Remediation Project Case Study

ARCADIS was contracted in 2000 to lead the development, evaluation and selection of a final groundwater remedy for this 94-acre site in California. As part of this work, ARCADIS is also participating in the evaluation of innovative technologies with the potential to treat soil impacts in the multiple source areas across the site. Specifically, the project is focused on the remediation of seven ...

Groundwater remediation with Hydrogen Release Compound

A substantial manufacturing site in Harlow, Essex, was contaminanated with chlorinated solvents used in degreasingoperations. The main compounds of concern were trichlorethene (TCE), trichlorethane (TCA) carbon tetrachloride (CT) and daughter products. The groundwater was at a depth to water of approximately 1.75m with a river around 600m to the north. Glacial deposits included variable clay ...

Sonic making inroads on PCB remediation?

The Sydney Tar Ponds of Nova Scotia are the result of a century of coal mining and steelmaking, which left behind 900,000 tonnes of chemical waste. About 5 per cent or 45,000 tonnes of this waste is contaminated with high levels of PCBs. Two years ago a federal-provincial plan was announced to clean up the Tar Ponds over 10 years at a cost of $400 million, and this led to the creation of the ...

Important Facts About Saltwater Remediation

Soil that has suffered erosion due to salt, generally becomes useless to any kind of vegetation. This soil becomes crusty and if a lot of acreage is involved, it can cause upsets in ecosystems as well. While researchers have found some ways to treat these areas, the time those processes took were long and tedious. Thanks to today's technology for ...
