SEDIMENT MOVEMENT:
ADDITIONAL CONSIDERATIONS
Sediment movement and accumulation is a natural, ongoing process. Flowing water, for instance, can erode, deposit and resuspend sediments. Over time this can change the distribution pattern of contaminated sediments, reexposing more biota (plant and animal life) to potential toxins. This process can also result in uncontaminated sediments (e.g.—from bank erosion) covering contaminated sediments in a way that reduces the exposure of potential toxins to biota.
