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 material in question is primarily composed of clay materials having colliodal 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 reproducibiliity 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 described in reference 1, and to test the other set by any chosen method. The only restiction imposed was that if the chosen method involved filtration through asbestos or glass fibers, the suspended materila 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.
