Turbidity is caused by particles in the water that make it cloudy or opaque. These particles can be from a variety of sources, including algae, sediment, and pollution. Turbidity can also be caused by naturally occurring substances like minerals and clay.
While turbidity itself is not necessarily harmful, it can be a sign of other problems in the water that could be harmful to human health. For example, high turbidity can indicate the presence of harmful bacteria or viruses. It can also block sunlight from reaching aquatic plants, which can disrupt the food chain. Additionally, turbidity makes it more difficult for people to see underwater, which increases the risk of drowning.
There are several ways to reduce turbidity in water, including filtration and aeration. Treatment with chemicals like alum or polymers can also help to settle out particles and clear up the water. In some cases, simply allowing time for sediments to settle will eventually improve water clarity.
