Dichloroacetonitrile in Saint Augustine South Florida Water

Unhealthy Levels of Dichloroacetonitrile in the Water Supply of Saint Augustine South Florida Homes

Dichloroacetonitrile is a disinfection byproduct that can form when chlorine used in treatment reacts with natural organic matter. Because it forms during disinfection, it may be present even when water looks clear and has no noticeable odor, so you can’t rely on taste or smell to know if it’s there. For homeowners in Saint Augustine South and throughout St. Johns County, the only way to be certain is testing — especially with our region’s hard groundwater and coastal humidity, which affect local water chemistry and treatment needs.

Levels of disinfection byproducts such as dichloroacetonitrile can shift with changes in source water, seasonal organic material, and how utilities adjust treatment. Though often discussed alongside other chlorinated byproducts, each compound reacts differently in distribution systems and with filters. If you’d like more consistent control over the water used for showering, cooking, and laundry in your Saint Augustine South house, a whole-house solution treats water where it enters the home so every tap benefits — rather than relying on a single faucet device.
