While chlorine is the global standard for neutralizing waterborne pathogens, its interaction with naturally occurring organic matter—such as decaying vegetation—creates Disinfection Byproducts (DBPs). The most prevalent of these are Trihalomethanes (THMs), such as chloroform (CHCl₃), and Haloacetic Acids (HAAs). Scientific research indicates that long-term exposure to these compounds is associated with an increased risk of bladder cancer and potential adverse reproductive outcomes. Because THMs are volatile, they can enter the body not only through ingestion but also through inhalation and dermal absorption during hot showers. Regulatory agencies set strict limits on these levels, but many households seek to eliminate them at the point of use to minimize cumulative lifetime exposure. This content is AI-generated.
