Description:
Permeable reactive barrier technology is an in-situ approach for remediating groundwater contamination that combines subsurface fluid flow management with passive chemical treatment. Factors such as the buildup of mineral precipitates, buildup of microbial biomass (bio-fouling), and changes in subsurface transport combine to govern long-term performance of in situ Permeable Reactive Barriers. A detailed understanding of these factors is critical to understanding how long these passive systems will remain effective and what methods may be employed to improve their performance and extend their lifetime.
