When soil is exposed during construction activities, runoff that occurs during storm events tends to pick up soil particles and carry them to the nearest body of water. Larger particles, such as pebbles and sand, quickly settle to the bottom once the flow rate slows.
However, clays and fine silts settle much more slowly and tend to stay suspended. These suspended particles result in turbidity that can travel many miles in streams or keep ponds and lakes looking muddy for a long time after a storm. Turbidity reduces the productivity of the affected waters, decreases their recreational value, and increases treatment costs for industrial or drinking water plants. Dober’s Water Treatment division offers natural treatment options which reduce turbidity in impounded water.
