Coastal Green Stormwater Infratructure: Wetlands in Wilmington
NC stormwater managers evaluate wetlands in coastal watersheds. As reported in the Journal of Environmental Quality, "eight storms [were monitored] and showed that the Wade Park Wetland retained and/or removed 50 to 75% of the inflowing volume of runoff. The average load reduction for fecal coliform bacteria was 99%, with an overall concentration reduction of more than 90%". Additional studies look at wet detention pollution removal rates.
