Haloacetonitriles in Piedmont Florida Water

Unhealthy Levels of Haloacetonitriles in the Water Supply of Piedmont Florida Homes

Haloacetonitriles form when disinfectants like chlorine or chloramine react with natural organic material in source water. Even though they usually occur at low concentrations, many Piedmont homeowners choose to reduce them as part of improving overall water quality. Because these byproducts can be created during routine disinfection, they may be present even when water looks clear and tastes normal; the only way to know for sure is a laboratory water test that measures whether haloacetonitriles are in your supply and at what levels.

Haloacetonitriles are members of the broader disinfection byproduct family that also includes trihalomethanes (THMs) and haloacetic acids (HAAs). Their concentrations can change over time depending on the source water and treatment practices, so a single test may differ from another taken later. In North Florida, where municipal and private well sources can vary across neighborhoods and hardness is typically moderate, some residents begin investigating treatment after sensing stronger chlorine odors, different tastes, or skin sensitivity from highly chlorinated water. Those signs aren’t specific to haloacetonitriles, which is why many Piedmont households opt for a whole-house system to protect water used for drinking, cooking, bathing, and laundry.
