Abstract

Stormwater moves various pollutants into our surface waters and the Salish Sea. Several green stormwater infrastructure approaches are available to reduce storwmater flows including bioretention systems, green roofs, and pervious pavements. Furthermore, some of these techniques have been shown to reduce pollutants in stormwater thus reducing toxicity to aquatic organisms. In this talk, we will present data on the ability of conventional pervious pavements (concrete and asphalt) and pavements that have been modified with a proprietary material to reduce pollutants that are commonly found in urban stormwater. We will also present results of toxicity studies with aquatic organisms exposed to untreated stormwater and stormwater that has passed through pervious pavements.
