Sedimentation

The most prevalent source of agricultural water pollution is soil that is washed off of fields. These fields have been treated with fertilizers and pesticides, which over time have accumulated heavy metals that are then transferred to lakes and streams. The excess particles cloud the water blocking vital oxygen and sun for the aquatic plants.

Nutrients

When these sources exceed the plants needs or if these nutrients are applied before a heavy rain then the opportunity for these excess to wash into aquatic ecosystems exists.
