Green Remediation - Incorporating Sustainable Environmental Practices into Remediation of Contaminated Sites


Quiz Questions

1.Green Remediation is the practice of considering all environmental effects of remedy implementation and incorporating options to maximize net environmental benefit of cleanup actions.
True
False
2. Green remediation reduces the demand placed on the environment during cleanup actions, otherwise known as the “footprint” of remediation, and avoids the potential for collateral environmental damage.
True
False
3.Green remediation builds on environmentally conscious practices already used across business and public sectors, as fostered by the Agency’s Sectors Program, and promotes incorporation of state-of-the-art methods for __________________.
Conserving water
Improving water quality
Increasing energy efficiency
All the above
None of the above
4.Green remediation does not promote adoption of sustainable strategies at every site that require environmental cleanup, whether conducted under federal, state, or local cleanup programs or by private parties.
True
False
5.The U.S. Department of Energy (DOE) has remediated contaminated areas at more than 100 installations and other locations. The Department has identified approximately 4,000 contaminated or potentially contaminated areas on 22 installations and other locations. Most of DOE’s remediated areas will require ground water treatment and monitoring or other long-term stewardship efforts.
True
False
6.The best management practices of green remediation balance core elements of a cleanup project are represented in ____________________________.
Figure1
Figure2
7.Land and ecosystems are not one of the core elements of the green remediation system.
True
False
8.One of the core elements of the green remediation system is air emissions which minimizes use of heavy equipment requiring high volumes of fuel and minimizes dust export of contaminants.
True
False
9.The objective of green remediation is to:
Achieve remedial action goals
Decrease operational efficiencies
Increase total pollutant and waste burdens on the environment
10.Site fingerprinting is an ecology-based planning tool focused on the protection of natural resources during site development.
True
False
11.Green remediation practices for waste management do not encourage consumers to consider lifecycle cost (including natural resource consumption) of products and materials used for remedial activities.
True
False
12.Energy requirements constitute a core element of green remediation. Significant reductions in fossil fuel consumption during treatment processes can be achieved through (1) greater efforts to optimize treatment systems, and (2) use of alternative energy derived from natural, renewable energy sources.
True
False
13.Effective design of an LFG energy system includes adequate conditioning that ensures converted gas is free of vapor and remaining contaminants or impurities, and operational practices that minimize liquid waste streams.
True
False
14.Waste-to-energy (WTE) systems convert _________________________________.
Solid waste into electricity
Liquid waste into alternative fuel
Either of the two
Neither of the two
15.A permeable reactive barrier (PRB) is an in situ ground water treatment technology that combines a passive chemical or biological treatment zone with subsurface fluid-flow management. PRB construction commonly involves subsurface placement of selected reactive media into one or more trenches perpendicular to and intersecting ground water flow. Passage of ground water through the barrier is driven by the natural hydraulic gradient, requiring no external energy.
True
False
