| Use advice for data set | When utilizing this dataset for Life Cycle Assessment, users should take into account the specific context of the groundwater remediation process, including the composition and concentration of contaminants, the hydrogeology of the area, and the performance characteristics of the treatment technology involved. It is essential to consider the environmental impact of the construction and operation of the remediation system. Additional data on similar processes or average industry practices should be sought to check the representativeness and validity of the dataset. Where data gaps exist, users should employ conservative assumptions or refer to the most relevant available literature and practices. Emissions that are not accounted for in this dataset should be estimated based on best available techniques, and the omission of such emissions should be clearly documented and justified in the assessment. |
| Technical purpose of product or process | The described industrial process involved in the extraction and treatment of contaminated groundwater is utilized for environmental remediation purposes. It is specifically implemented in sites where groundwater pollution poses a significant threat to the environment and human health, such as military bases, industrial sites, and areas with historical chemical spills or leaks. The process is designed to handle the clean-up of contaminated sites through a series of technologically advanced units including extraction wells, air-stripping units, catalytic oxidation units, granular activated carbon units, and treatment facilities. |

| 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. |

| 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. Model extraction wells were constructed using an eight inch auger (80 kW at 5 m/hour) and were composed of PVC well pipe, filter pack, grout, and a 0.75 kW (1 hp) well pump. |
