Abstract:
A stormwater treatment system which comprises a housing having a first filter layer and a second filter layer positioned within the housing. The first filter layer absorbs contaminants from stormwater to produce a first treated stormwater having an effluent concentration that meets the USEPA Water Quality Criteria when stormwater permeates the first layer. The second filter layer precipitates substantially all of the dissolved contaminants remaining in the first treated stormwater when the first treated storm water permeates through the second filter layer.
