| Use advice for data set | Users of this dataset should be aware that the specific details of the construction and implementation of the caisson-based PRB system are based on design documents for Dover AFB and may not be universally applicable. When utilizing this data for other sites, ensure that local conditions are equivalent or adjustments are made to the design to accommodate different hydrological or geological situations. It is also essential to note that some unit processes, inputs, or emissions might be estimated or omitted based on available literature and calculations rooted in fundamental principles; therefore, further verification is recommended when applying the data in a new context. |
| Technical purpose of product or process | The described industrial process involves the use of a caisson-based gate configured as part of a Permeable Reactive Barrier (PRB) system. This system, incorporating a 2.4 m diameter caisson and a 1.2 m × 1.2 m column of Zero Valent Iron (ZVI), is specifically designed for in-situ groundwater remediation. The funnel-and-gate configuration of the PRB allows for the natural gradient flow of groundwater through the reactive cell, facilitating the degradation or capture of pollutants. This technology is implemented for environmental management and remediation at sites like Dover Air Force Base, where containment and treatment of contaminated groundwater are necessary. |
