Jacksonville’s drinking water comes from the Floridan aquifer, which supplies drinking water to over 10 million people who use different water softeners services to make sure they get clean water.

Disinfection Byproducts (DBPs) are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. EPA regulates two variations of DBPs: Total Trihalomethanes (THHMs) and Haloacetic Acids 5 (HAA5). According to the most recent report, the maximum level exceeded the regulatory threshold for TTHMs. Although these chemicals are only loosely regulated at this time, EPA has concluded that high levels of DBPs are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.
