HRX Well Design, Cost, and Sustainability Tool and Analysis: Demonstration and Validation of the Horizontal Reactive Media Treatment Well (HRX Well(registered trademark)) for Managing Contaminant Plumes in Complex Geologic Environments
Abstract:
The HRX Well (registered trademark) design tool was developed to provide preliminary site design estimates to practitioners considering implementation of the HRX Well. Many HRX Well configurations are possible, but the applicability of any design is subject to site-specific factors. The tool allows the user to optimize the design based on user-provided values and using the equations described in Divine et al. (2018). Supplemental literature values can also be used as inputs to support high-level estimations. The tool predicts well length, capture width, and the number of wells required to meet target treatment goals. In addition, the associated costs and sustainability implications are calculated, which can further inform design selection. For many sites, a site-specific numerical flow and transport model may be useful for final design, as well as predicting and assessing HRX Well performance.
