Use advice for data set When utilizing this data set for environmental impact assessment or life cycle assessment (LCA), consider the following: 1) Ensure the GAC unit modeling aligns with the specific site conditions and pollutant types present at the site being assessed. 2) Take into account that the effectiveness of the GAC may diminish over time and may require regeneration or replacement, which should be included in the overall assessment. 3) Emissions or other environmental impacts not included in the dataset should be estimated using available literature or fundamental environmental engineering principles. 4) Omitted data must be noted, and assumptions and estimations should be justified within the assessment report.
Technical purpose of product or process The granular activated carbon (GAC) unit and groundwater pump and treatment process are typically employed in environmental remediation to extract and treat contaminated groundwater. This process is particularly suitable for applications at sites like military bases, where groundwater may be polluted with various contaminants. The GAC effectively adsorbs organic compounds, thereby purifying the water. The entire pump and treat system (PTS), inclusive of the GAC unit, is designed for the sustained reduction of pollutant concentrations, providing both rapid initial cleanup and longer-term remediation of contaminated sites.
Classification
Class name : Hierarchy level
  • ILCD: Other Services / Repair and maintenance
General comment on data set PTS removes the contaminated groundwater by pumping and use of aboveground treatment facilities. A PTS provides quick initial reductions in contaminant concentrations, but often results in a slow, steady reduction for the long-term.

Technological representativeness
Technology description including background system The PTS was modeled with five subsystems: extraction wells, air-stripping unit (ASU), catalytic oxidation unit (COU), granular activated carbon (GAC) unit, and treatment facilities.The model GAC unit was two steel drums each containing 180 kg (400 lb) of GAC.
