If the reactive material used in a PRB system to clean a contaminated groundwater being spent and exhausted, it may be reactivated for further reuse for sustainability point view and cost effectiveness. Is there any large scale studies?
The contaminants are chlorinated organics mainly SVOC's. Yes, it is a continuous wall and/or funnel and gate system or even soil mixing barriers.The reactive material I am concerned is ZVI /activated carbon. However, any case study data will be very beneficial. Our site has high metal concentrations (mainly Pb and Zn) as well.
