| sediment |
Loose particles of sand, clay, silt, and other substances that settle at the bottom of a water body. They come from eroding soil and from decomposing plants and animals. Wind, water, and ice often carry these particles great distances. Many sediments in rivers, lakes, and oceans are contaminated by pollutants, such as DDT and PCBs.
