To investigate the behavior of heavy metals in infiltration facilities receiving urban road runoff, we performed batch tests, which mimicked the sorption of heavy-metal species in road runoff by soakaway sediments. In soakaway sediment leachates, Ni and Cu were dominantly present as stable complexes, whereas most Zn existed as free ions and labile complexes. Ni and Cu in road runoff were adsorbed by all the soakaway sediments, whereas Zn was released from some soakaway sediments. Instead of the total Zn content in the soakaway sediments, the soluble fraction of Zn (i.e., the concentration of Zn released from sediments by deionized water) was a governing factor for the sorption from soakaways receiving road runoff; however, the behavior of Ni and Cu was not well explained by the total metal content, soluble fraction, and organic content. Desorption tests are useful in identifying soakaway sediments with limited adsorption capacities for Zn. The control and management of sediments based on desorption tests would be effective in minimizing groundwater contamination by heavy metals through infiltration facilities.
