Long-term leaching of accumulated heavy metals from the filter media of stormwater infiltration systems into groundwater, and its subsequent movement into receiving waters, is a concern for stormwater management in urban landscapes. This study provides a critical understanding of the fate of heavy metals, in particular zinc, in the subsurface to improve stormwater management. We studied the sorption behavior of zinc during its transport in soil using batch and column experiments. The use of sorption parameters from batch studies failed to suitably describe the zinc breakthrough curves simulated with the HYDRUS-1D model. While a sharp breakthrough curve front was expected due to the nonlinear..View full abstract
