Abstract: The use of a permeable, retentive treatment system could remove both organic and inorganic contaminants while still allowing flow. A testing procedure for determining the amounts of priority pollutants retained by natural, low-cost permeable materials is presented. Coal, fly ash, limestone and a clayey soil have been tested. Simulated leachates containing benzene, toluene, trichloroethylene, methylene chloride, lead, cadmium and arsenic have been used. This information would be the criteria required for the design of a permeable treatment system. The retentive capacities of materials would be used to determine the required layer thicknesses.
