Abstract: We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of oil and grease occur in stormwater runoff draining urban areas, with a substantial potential to adversely impact receiving waters. Furthermore, modeling has shown that waters off-shore from urban areas can be protected by implementing controls on a relatively small fraction of the watershed. However, traditional technologies designed for industrial and municipal wastewater do not have the capability to remove oil and grease from stormwater on a cost-effective basis. Four structural control technologies are described which have the potential for being practical tools for enhancing water quality through the removal of oil and grease from urban stormwater runoff.
