Turbidity is caused by include organic materials such as algae, and inorganic materials such as silt and sediment. Suspended solids in a body of water are often due to natural causes. These natural solids include organic materials such as algae, and inorganic materials such as silt and sediment.
Is turbid water a health risk? Since a wide variety of particles cause turbidity, it is difficult to determine the health risk. The health risk is usually not the particles themselves but the impact of the suspended particles on disinfection of the water. Also, changes in turbidity can flag a potential problem and may indicate new source of contamination of the water. Surface water or shallow wells tend to have higher levels of turbidity.
