Chlorine Taste & Smell
A chlorine taste or smell is usually a sign your system is disinfecting properly — but a sudden change is worth understanding.
Short answer: Chlorine and chloramine are common disinfectants in New Jersey public water. A mild chlorine taste or smell is normal, especially seasonally. A sudden strong change is worth checking against your CCR or reporting to your utility.
Why it's there
Public water systems add chlorine or chloramine to control bacteria and other pathogens through the distribution system. Dosing can vary seasonally, and a temporary increase sometimes follows a main break, repair, or precautionary flushing.
Step-by-step
- Refrigerate a pitcher of water for a few hours — chlorine taste often fades with time and chilling.
- Check your CCR or utility website for any recent notices about disinfection changes.
- If the taste is new, strong, and persistent, contact your utility to ask about current dosing.
- Consider an activated-carbon filter if the taste bothers you day to day (see Whole-House Filters).
Common mistakes
- Assuming any chlorine taste means something is wrong
- Not checking for a seasonal or maintenance-related explanation before buying treatment
Official sources
- Your utility's current CCR
- U.S. EPA disinfectant residual guidance
