3.4 Turbidity

Turbidity is the state of relative clarity or cloudiness of water. Many factors can contribute to increased turbidity. The most obvious are suspended sediments consisting of various sand, silt, clay and gravel particles. These may be introduced by soil erosion, urban runoff, bottom-dwelling aquatic creatures that stir up settled sediments, or human activities such as […]
