Use advice for data set
| Data users should account for this dataset within Life Cycle Assessments focusing on soil contamination control strategies that are in situ, impermeable barriers such as the sheet pile walls described. The data includes long-term maintenance of these control technologies and the energy and material consumption onsite without accounting for any transportation or final material disposal processes. Considerations regarding technological applicability should include the indefinite maintenance period of the infrastructure as well as the local conditions for the hydraulic interventions. Abstraction and treatment facilities are presumed to operate for at least 100 years, although actual operation timeframes are indefinite. |
Technical purpose of product or process
| The described process pertains to a risk management strategy specifically used for the containment and control of soil contamination at one of the largest polluted sites in Denmark. The process does not eliminate the pollution but instead focuses on indefinite maintenance and containment through the use of continuous sheet pile walls. The hydraulic control component involves the abstraction and treatment of contaminated groundwater using activated carbon filtration to manage the pollution risk within the contaminated zone. This strategy is used to prevent further environmental dispersion of pesticides in the soil over an assumed timeframe of 100 years. |

Class name
:
Hierarchy level
|
| A risk control strategy for contaminated soil that cannot eliminate pollution, and the site has installed steel plate continuous walls, which only involves maintenance of the installed steel plate walls. |

Functional Unit
|
The functional units include steel pile walls that have been installed in a pesticide contaminated site covering an area of approximately 20000 square meters, 100 years of maintenance work, and related hydraulic control engineering.

Technological representativeness
|
Technology description including background system
| Continued encapsulation involves maintenance of the sheet pile wall, which is already installed, for an indefinite period. Groundwater is abstracted from the contaminated area to remove infiltrating water and to maintain a gradient towards the site. The abstracted water is treated by activated carbon filtration near the site. A 100-year timeframe is assumed although the time frame is actually indefinite. |
