    Total suspended solids, as a measurement of mass are reported in milligrams of solids per liter of water (mg/L) 18. Suspended sediment is also measured in mg/L 36. The most accurate method of determining TSS is by filtering and weighing a water sample 44. This is often time consuming and difficult to measure accurately due to the precision required and the potential for error due to the fiber filter 44.

    Solids in water are either in true solution or suspended. Suspended solids remain in suspension because they are so small and light. Turbulence resulting from wind and wave action in impounded water, or the movement of flowing water helps maintain particles in suspension. When turbulence decreases, coarse solids quickly settle from water. Very small particles, however, may have colloidal properties, and can remain in suspension for long periods even in completely still water.

    The distinction between suspended and dissolved solids is somewhat arbitrary. For practical purposes, filtration of water through a glass fiber filter with openings of 2 μ is the conventional way of separating dissolved and suspended solids. Dissolved solids pass through the filter, while suspended solids remain on the filter.
