Abstract : One phase of a comprehensive study being conducted by the U. S. Army Engineer District, Charleston, involves the determination of the amount of potential shoaling material being transported in suspension in the waters of the harbor and its tributaries. Parallel investigations reveal the fact that the material in question is primarily composed of clay minerals having colloidal characteristics. Although there are a number of test procedures in existence for determination of the concentration of suspended sediments, there is a paucity of data concerning the degree of accuracy and reproducibility of each. The testing program described herein was designed to produce more information in this respect. Each laboratory was instructed to test one set of replicates by the membrane filtration method and to test the other set by any chosen method. The only restriction imposed was that if the chosen method involved filtration through asbestos or glass fibers, the suspended material must first be flocculated with sodium chloride. Two of the laboratories chose to filter through glass fibers and the other two through asbestos mats (so called Gooch crucible method). Results obtained were analysed by standard statistical procedures.
