| Abstract: | The potential effectiveness of a constructed passive net alkaline wetland in reducing human health risks from heavy metals
in surface waters was evaluated by using a multimedia model. Scenarios were developed using information available from site
reports, state, federal, and standard engineering sources. The scenarios replicated observed heavy metal concentrations in
the waters of a volunteer wetland and estimated the concentrations after implementation of a constructed passive net alkaline
wetland. The greatest reductions in risks are expected to occur soon after construction, with children benefiting more than
adults. |
