Haloacetonitriles in Orlando Florida Water

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

Haloacetonitriles are disinfection byproducts that form when chlorine or chloramine reacts with natural organic material in source water. They’re usually found at low concentrations, but many Orlando homeowners choose to address them as part of improving overall water quality. Because these byproducts can form during routine disinfection, they may be present even when water looks clear and tastes fine—especially in Central Florida, where warm temperatures and seasonal rain can influence source-water variability. A certified lab test is the only reliable way to know whether haloacetonitriles are in your home's supply and at what levels.

Haloacetonitriles belong to a wider group of disinfection byproducts that also includes trihalomethanes (THMs) and haloacetic acids (HAAs). Concentrations can shift with changes in source water and treatment practices, so one test snapshot may differ from another taken later. Many residents in Orange County begin exploring treatment after noticing stronger chlorine odors, altered taste, or skin irritation from heavily chlorinated water—signals that don’t specifically identify haloacetonitriles but do suggest looking into whole-house options that protect drinking, cooking, bathing, and laundry water throughout the home.
