Use advice for data set
Users of this dataset should consider the specific regional context and contaminant profile of the groundwater at the Jiangsu site when applying the data for similar remediation activities. The representativeness of the material allocation, energy consumption, and emission factors may vary depending on the geographic location and technological practices implemented elsewhere. It is essential to ensure methodological consistency when integrating this data with other LCA datasets, particularly with respect to the inclusion or exclusion of recycling processes for the materials used (aluminum, HDPE, and steel) and the modeling of the use phase behavior.

General comment
The site is a closed pesticide manufacturing plant. The water table is located around −4 m (below the ground). The aquifer mainly consists of silty sand with approximately 20 m depth, and the aquitard containing silty clay is located at about −24 m to −33 m. Other hydrogeological parameters include water content 26.33 %, hydraulic conductivity 0.00105 cm/s, groundwater gradient 0.008, Darcy velocity 0.73 cm/d, and actual velocity 1.83 cm/d. High concentrations (hundreds of mg/L) of VOCs were detected in the groundwater including BTEX, vinyl chloride (VC), 1,2-dichloroethane (1,2-DCA), chlorobenzene, 1,2-dichlorobenzene, and 1,4-dichlorobenzene.

Technical purpose
The air stripping unit described by this dataset is utilized in the ex-situ remediation process of contaminated groundwater within the framework of pump and treatment systems. Specifically, it is for the treatment of groundwater polluted by pesticides at a closed manufacturing plant in Jiangsu Province, China. This equipment, which is constructed using aluminum, high-density polyethylene (HDPE), and steel, is engineered to remove volatile compounds from groundwater by transferring them to the air phase through the process of air stripping.
