Permeable Reactive Barrier Clause Samples

Permeable Reactive Barrier. The PRB was installed in 1999 as a technology demonstration project. The capacity of the PRB to transmit water has diminished to the extent that it now serves as a groundwater flow barrier and represents the downgradient boundary of the AOA. Because of this, future decommissioning of the PRB is dependent on the progress of the groundwater remedy optimization system (Section 3.3.4). Routine monitoring at the PRB occurs as part of the OU III semiannual monitoring and results are provided in annual groundwater reports.
