EXAMINATION OF THE ELUTRIATE TEST, A SCREENING PROCEDURE FOR DREDGING REGULATORY CRITERIA

Water quality parameters were considered in a series of tests, including the Standard Elutriate Test designed to appraise the elutriate techniques. Both the conditional stability constant and the complexing capacity of the elutriate were greater than those of background waters. Although the concentration of the Standard Elutriate can be greater than 1.5 times the original concentration for the four heavy metals considered (Zn, Hg, Pb, Cd), it may be still less than the standards for drinking water and fresh water or marine aquatic life. Thus, such releases themselves should not significantly affect the water quality. It appears that improvement of the existing dredging regulatory criteria concerning Hg, Pb, and Zn is desirable. On the other hand, tests indicate that the release of phosphorus can be large and might significantly affect the water quality in actual open water disposal.
