Does turbidity affect THM levels?

Turbidity does play a significant role in water quality, particularly regarding the formation of trihalomethanes (THMs), which are disinfection byproducts. When water is turbid, it indicates the presence of suspended particles, such as organic material and sediment. These particles can provide a surface for chemical reactions, and when chlorine is used for disinfection, it can react with the organic matter present in the water, leading to higher levels of THMs.

While not directly attributed only to turbidity, the general understanding is that higher levels of turbidity can contribute to increased formation of THMs due to the additional organic compounds present in the water that chlorine can react with. Hence, saying that turbidity does not affect THM levels is misleading because, in reality, there is a known correlation where increased turbidity can lead to higher THM levels.

This is why a more accurate answer would reflect the positive relationship between turbidity and THM levels, particularly in the context of how both components interact during water chlorination processes.
