Why is it used?
Permeable Reactive Barriers (PRB) are ideal when in-situ remediation of contaminated sites are required whilst limiting the impact on groundwater flow.
How does it work?
Usually, a reactive barrier is installed as a narrow trench beneath the ground surface so that contaminated groundwater passes through the barrier, and emerges ‘clean’ because contaminates are treated and/or removed by the reactive medium of the barrier.
Typical treatment media used as a permeable reactive barrier wall include granular iron, activated carbon, engineered bacteria, chemicals, and special clays.
