Engineered Soils, Bioswale, Bioretention Soil Media
Biotreatment Soil Media (BSM) is a critical element of the bioretention system. The BSM has a ratio of inorganic and organic materials to allow the appropriate infiltration rates for stormwater; facilitate pollutant removal through chemical, biological and physical processes; and provide a sufficient growing medium for plants.
