The Results of an Interlaboratory Study of a Column Method for Leaching Solid Wastes


A method for generating aqueous leachates from solid wastes in a column apparatus has been drafted by ASTM Subcommittee D34.02.02 on Column Extraction Methods. The method was subjected to a five-laboratory study using fly ash as a waste material. The within laboratory relative standard deviation for metals (based on the results from three laboratories with multiple columns) was found to be approximately 35%. The overall single test reproducibility in terms of relative standard deviation (based on the results from these same laboratories) was approximately 55%. This excludes interlaboratory analytical effects because all analyses were performed by a central laboratory.
