    The Synthetic Precipitation Leaching Procedure is a quick and inexpensivemethod to determine: 1. The mobility/leachability of low volatility organic and inorganic analytes in liquids, soils, and wastes. 2. The measure of desorption of contaminants from soil (rather than adsorption). 3. The possibility of leaching metals into ground and surface wate...

Chloroform 9. Cyanide 10. DDT 11. Lead 12. Mercury 13. Methane 14. Polychlorinated Biphenyls 15. Styrene 16. Toulene 17. Trichlorophenol 18. Vinyl Chloride

    SPLP testing method 1312 from the USEPA SW-846 compendium of analytical and test methods is a single point leachate test designed to simulate very specific precipitation conditions. Samples are preliminarily evaluated for solids and particle size. Using a 1:20 solid-to-liquid ratio, the samples are then leached with extraction fluid calibrated to p...

    In some cases, SPLP testing may be supplemented by additional testing methods. This is because: 1. Pore size of colloidal inorganics may be underestimated because leachate is filtered through a 0.6-0.8 µm filter, so anything above this size may be underrepresented in the test data. 2. Interconversion of metal species with multiple oxidation states ...
