What is the limit for Total Trihalomethanes (TTHM) in water?

The limit for Total Trihalomethanes (TTHM) in drinking water is set at less than 80 Parts per Billion (PPB). This regulatory limit is established to protect public health, as TTHMs are byproducts formed when chlorine used for disinfection reacts with natural organic matter in the water. Prolonged exposure to TTHMs has been associated with certain health risks, including potential cancer and reproductive issues.

Maintaining TTHM levels below this threshold helps ensure that the drinking water is safe for consumption, aligning with standards set forth by organizations such as the Environmental Protection Agency (EPA). Monitoring and controlling the levels of TTHMs is critical in water treatment processes to mitigate these risks and provide safe drinking water to the population. This understanding reflects the importance of adhering to established water quality standards for public health safety.
