Infiltration basin/trench RECOMMENDED RECOMMENDED ACCEPTABLE with cautions for [Potential stormwater hotspots PSH] RECOMMENDED RECOMMENDED unless target TMDL pollutant is a soluble nutrient or chloride
Filtration Some variations NOT RECOMMENDED due to poor phosphorus removal, combined with other treatments RECOMMENDED RECOMMENDED ACCEPTABLE RECOMMENDED for non-nutrient impairments
Filtration (including green roofs) ACCEPTABLE if P removal in media is considered RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED for non-nutrient impairments
Iron enhanced filters RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED
Wetlands Some variations NOT RECOMMENDED due to poor P removal, combined with other treatments. NOT RECOMMENDED
except for wooded wetlands
RECOMMENDED RECOMMENDED
but no use of natural wetlands
RECOMMENDED
