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 __________________. |

|
Improving water quality |
|
|
Increasing energy efficiency |
|
|
All the above |

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. |

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 |

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 |

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 |

Waste-to-energy (WTE) systems convert _________________________________. |
|
|
Solid waste into electricity |
|
|
Liquid waste into alternative fuel |
|

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. |
