Parking Lot and Sidewalk

Research by the DRSCW shows that chloride is a proximate stressor in the Upper DuPage and Salt Creek river systems. This means that it was one of the variables that best correlates with biodiversity of fish and macroinvertebrates.

The communities in the DRSCW watersheds primarily use rock salt for deicing, and most of them use liquid calcium chloride as a pre-wetting agent or an anti-icing agent. A few communities use CMA or potassium acetate in addition to rock salt, and there is limited use of proprietary alternative products.
