4 CONCLUSION
The choice of the reactive material for PRBs requires
determining the hydraulic conductivity of reactive materials
with regard to the relative density and strain conditions
(effective stress) in the barrier. It is necessary to carry out
“compatibility tests”, i.e. test of contaminated groundwater
influence on hydraulic properties of the selected material.
Achieved results for synthetic leachate showed less than
3-fold decrease of zeolite-sand mixtures permeability.
Landfill leachate caused decrease of hydraulic conductivity
almost by two orders of magnitude due to inorganic
precipitation and biological growth.
