Permeable reactive barriers (PRB) is one of the innovative technologies of ground-water remediation and
alternative to energy-intensive method “pump and treat”. The PBR is the engineering construction in the
ground, filled with reactive material, where the contaminants from groundwater flow are immobilized or reduce
to acceptable values. Since the invention of PRBs, a several installation methods were used to construct
including conventional and alternative trenching techniques, injection, deep soil mixing and various type
of construction depending on the parameters of contaminants and field conditions. Despite a wide ranging,
there are still unresolved issues about installation methods and long term-performance. This article presents
an overview of the PRB technology, which includes state of the art, advantages and limitations, and prospects
for the use in Poland.
