Enclosed Swamp
Higher levels of salt and chemicals in water bodies with no outlet
Abandoned Beaver Dam
Wet Meadow Semi-treated wastewater sludge micro-pollutants (LAS and NPE) dissolved carbon pathogens heavy metal phosphorous nitrogen Water in sludge is evapotranspirated out
Ideal for seed germination
Estuary
Heavy metals are sequestered to soil banks (easier for removal)
Sludge is dewatered and decreased in volume by 95-99%
Lives 6� above and below the water line
Brackish water
Filtered water
Decreased refuge pools for keystone species Fundulus heteroclitus
Sludge Treatment Reed Bed
Fresh water Roots can live in both saturated and moist soil (dive to fresh groundwater in saline environments)
Salt water
pollutional nitrogen phosphorous macronutrients
Freshwater Wetland Silicon cycling
Dune stabilization

Salix alba
Populus Phragmites australis
Phragmites highway skrim catches stormwater runoff and remediates before dispersing into estuary
Populus + Salix bebbiana filter air pollution within 300’ of highway Salix bebbiana Brassica juncea Festuca rubra Inorganic compounds from land use stabilized and removed with hyperaccmulating perennials Amsonia hubrichtii Liastris spicata Scirpus atrovirens
Salix alba and Populus reate petroleum remediation buffer for potential petroleum plumes; future core tetsing site to monitor
