Sediment
The term for soil that settles in water is sediment. Sediment is the material that is carried and deposited by water, wind, or glaciers.
The fluid just settles in the pores (air pockets/holes)of the material.
The process by which the material carried by a stream or river settles or is dropped is called deposition. This occurs when the velocity of the water decreases, causing it to lose the energy needed to carry sediment, which then settles to the riverbed.

Foreign material that is added to air or bodies of water are called pollutants. Examples would be smog, oil, smoke, and trash.
