in the mid of drilled holes. There are six cases in which the design of PRB can be
summarized (Gautam C Ijoor 1999) which are shown in Fig. (8.5).

Permeable reactive barrier’s one foremost advantage over the pump and treats system
is its passive method of working, i.e., without any labor or energy input. The barrier
