You should know
Total trihalomethanes (TTHMS) can form when chlorine used to disinfect water reacts with organic matter already present in the water, such as leaves or plants. Alternative disinfectants, removing organic pre-water treatment, monitoring, and filtration are all ways to reduce TTHMs in your drinking water.
Studies have shown that long-term exposure to TTHMs put people at risk of cancer, reproductive issues, and even liver, kidney, and nervous system damage. (Another reason to never drink water from the pool!)
