Metals Removal Technologies for Urban Stormwater

This study, on innovative methods for the capture of metals from stormwater, mainly focused on two major areas of investigation: media filters and swales.

Twelve media were chosen for initial evaluation. The three best performing media: peat-sand mix, compost, and zeolite were then selected for in-depth study. The results of this investigation emphasize the importance of characterizing the stormwater before selecting a treatment media since the type and quantity of metals, pH, and other runoff characteristics can vary a great deal between sites.
