Storm Water Pollutant Removal Performance of Compost Filter Socks.

The article discusses research that evaluated the potential for compost filter socks with or without the addition of a flocculation agent to significantly remove numerous pollutants from storm water runoff. The polluting materials evaluated included suspended clay and silt particulates, ammonium nitrogen, and heavy metals. Rainfall simulation was applied to soil chambers packed with Hartboro silt loam. Runoff samples were analyzed for Escherichia coli and motor oil. Removal efficiencies for all pollutants were established.
