Water: Dredged Material Management

Dredged Material Testing and Evaluation

Evaluation of dredged material for ocean disposal under the MPRSA relies largely on biological (bioassay) tests. The ocean testing manual, commonly referred to as the Green Book, provides national guidance for determining the suitability of dredged material for ocean disposal.

Evaluation of dredged material for inland disposal under the CWA relies on the use of physical, chemical, and/or biological tests to determine acceptability of material to be disposed. The Inland Testing Manual (PDF) (176 pp, 9MB, About PDF) is national guidance which provides best available methods for this CWA evaluation.
