TRACE METAL LEVELS IN SEDIMENTS DEPOSITED IN URBAN STORMWATER MANAGEMENT FACILITIES

ANDERSON B. C. / MARSALEK J. / WATT W. E. - ARTICLE DE PERIODIQUE - 2006

Characteristics of solids recovered from stormwater best management practice (BMP) facilities, including stormwater ponds, constructed wetlands, an infiltration basin, a biofilter, a stormwater treatment clarifier, and three-chamber oil and grit separators were described with respect to their metal chemistry. The chemical pollution of pond sediment triggered toxicity testing at some of the facilities studied, and sediment toxicity was confirmed at several sites.
