Toxic sediment

Sediments are most often transported by water (fluvial processes), wind processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. Glacial moraine deposits and till are ice-transported sediments
A grim reminded of the widespread result(s) of sediment is exacerbated with the all-too common warning of resulting and uncontrolled erosion.

We must take steps to mitigate erosion
