ABSTRACT

Research paper thumbnail of Critical issues for stormwater ponds: Learning from a decade of research

Water Science & Technology

The Queen's University/National Water Research Institute Stormwater Quality Enhancement G... more The Queen's University/National Water Research Institute Stormwater Quality Enhancement Group has been actively researching stormwater ponds for the past decade, using a fully instrumented on-line system in Kingston, Ontario, Canada as a representative field installation of this group of stormwater best management practices, along with comprehensive surveys of other facilities as well. From this body of research, the Group has concluded that there are a number of identifiable factors, termed critical issues, which will significantly influence the success, failure and sustainability of these BMPs. Such factors will be important to a very diverse group of stakeholders in stormwater management, including designers, owners/operators, regulatory authorities and the general public. These factors can be grouped within the categories of initial design, operation and maintenance, performance and adaptive design. From this work, it is concluded that the so-called first generation quantity-control ponds may be outdated today, compared with the modern focus on quantity and quality issues in the second generation systems; nonetheless, without consideration of these critical issues and flexible design practices which can account for emerging or future issues, the current systems also run the risk of becoming outdated before the end of their design lives.

Research paper thumbnail of Trace metal levels in sediments deposited in urban stormwater management facilities

Water Science & Technology, 2006

Characteristics of solids recovered from stormwater best management practice (BMP) facilities, in... more 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 reported trace metal concentrations in BMP sediments were assessed against the Ontario Sediment Quality Guidelines. Between 80 to 100% of all samples were marginally-to-intermediately polluted by Cd, Cr, Cu, Fe, Pb, Mn, Ni and Zn. Severe pollution of sediments was noted for Cr (122 microg/g), Cu (151 and 196 microg/g), Mn (1,259 and 1,433 microg/g), and Zn (1,116 microg/g), at several facilities studied, and even higher levels of metals were reported in the literature for certain oil and grit separators. With respect to individual BMPs, the severe pollution was found in sediments from oil and grit separators (for Cd, Cr, Cu, Pb and Zn), the stormwater clarifier sludge (Cu, Mn and Zn), a biofilter (Cu and Mn), an industrial area stormwater pond (Cu only), and a commercial/residential pond (Cr only). Finally, the chemical pollution of pond sediment triggered toxicity testing at some of the facilities studied, and sediment toxicity was confirmed at several sites.
