Return to Nonpoint Source Pollution: Suspended Sediments

Submerged aquatic vegetation (SAV) provides vital habitat for aquatic organisms, produces oxygen and traps modest amounts of sediment. However, if there are excessive amounts of suspended sediment, or hypoxic conditions occur - a state where the level of oxygen in the water is very low - SAVs die, thus leading to unhealthy conditions for fish and other aquatic organisms that rely on SAV for habitat. This image shows a healthy aqautic ecosystem free of suspended sediments and abundant with healthy SAVs.
