Enhanced medias are designed to remove organics, nutrients, and dissolved metals. Certain medias are designed to remove certain contaminants and there is no one media that can remove everything. Also, enhanced medias need time to work so the larger the media vessel is the better removal rates will be achieved. Storm water effluent data should be evaluated carefully to determine how much and what type of medias should be used and in what order they should be installed. This is critical to achieve benchmarks.
