Abstract
A sorptive-filtration system for removing at least one of negatively or positively charged ions, complexes or particulates from an aqueous stream. The system includes a) flow formed substantially from at least one of rainfall-runoff or snowmelt-runoff; b) a filter containment communicating with the runoff stream such that at least part of the stream passes through the filter containment; and c) a granular filter media disposed within the filter containment, the filter media having an amphoteric material applied thereto, wherein the amphoteric material comprises a metal selected from at least one of Fe, Al, Mn, or Si.
