In-situ monitoring and modeling of a reactive wall to reduce iron concentrations in groundwater under laboratory conditions
Project description:
Acid mine drainage (AMD) can cause major environmental problems. In natural waters, high levels of environmental pollution are caused by metals (e.g., iron), sulfides, and low pH. Introducing a reactive wall (PRB) into natural groundwater flow can reduce these pressures.
We are developing a reactive wall that reduces iron and sulfate concentrations of acid mine drainage. The processes taking place are monitored using optical sensing, for pH and O2 concentration. Dye films and fiber optic chemical sensors (FOCS) are used for this purpose. In addition, temperature is also measured using optical methods. The data obtained from the laboratory experiments will be modeled using MIN3P for a long-term period.
