wetlands

A wetland creates a natural water filter with a highefficiency ecological water treatment system below. The constructed wetland achieves the combination of water purification and a landscape scene

Physical processes of filtration

- Occurs in the rootzone or rhizosphere of the vegetation and in the soils - Bioremediation uses living organisms to degrade, transform, mobilize, or immobilize contaminants, thereby reducing toxicity

Bioremediation

- Soils and rock layers filter ground water to a high degree removing larger elemtents of contamination

Pickerelweed -Pontederia cordata: - Removes nitrates and nitrites - Creates habitat for local fauna - Creates optimal settings for rhizoremediation Woolgrass -Scirpus cyperinus: - Native grass with Spring, summer and fall foliage and flowers summer and fall - Prime specimen for bioremediation conditioning - Allows cover and habitat for amphibians and waterfowl - Becomes nesting grounds for waterfowl Bulrush -Schoenoplectus californicus: - Creates optimal settings for rhizoremediation to occur - attractive native sedge - provides green space and waterfowl habitat bird habitat - Removes influent suspended sediment, nitrates and phosphorus in wet land systems Soft rush -juncus effusus: - Food for wildfowl, upland game birds, marsh birds and songbirds - Removes Copper, Lead, and Zinc
