F.2.3 Sediment preparation
Sediment core or grab samples collected from the proposed area of dredging
should completely fill storage containers and be immediately refrigerated (4 EC)
following sampling to preserve sample integrity. Intact core samples, not
removed to a storage container, should be immediately sealed and refrigerated.
To ensure a representative sample, the sediment samples may be composited into
one bulk sample or combined according to horizontal or vertical stratification.
Approximately 20 L of material is needed to perform bulk sediment chemical
and physical characterization and volatile emissions testing. This volume can be
more or less depending upon the number of COC. If COC are trapped on the
same type of material only one chamber is needed to measure emissions, an
