Solid material suspended in natural water. Usually, this is a mixture of inorganic and organic material, living and dead. Suspended solids are not dissolved. They are particles of various sizes and buoyancy. Usually, the material is collected from a volume of water, and the collection protocol should specify the size or type of filter used to separate the suspended material from the water and dissolved material.
