Canadian military small arms firing range (SAFR) backstop berm soils contain high concentrations of Pb, Cu, Sb, and Zn. Three Teflon® cylindrical lysimeters were installed in the vadose zone of the backstop berm in order to characterize the pore water quality. Copper-Zn concentrations were below their respective Québec drinking water thresholds, and Pb-Sb concentrations were above the criteria in many cases, indicating that a metal vertical migration occurs in the vadose zone. Metal concentrations in pore water were, in decreasing order, Zn > Pb > Sb > Cu. Calculated annual metal leaching rates showed that a rather small portion of the metals in the soil were mobilized in the vadose zone, and that metals were a potential source of contamination for extremely long periods of time, highlighting the importance of finding ways to remediate such soils in order to limit metal mobility in SAFR backstop berms.
