Chlorine Taste & Disinfection Byproducts
Rochester uses chlorine to disinfect its water. While necessary, it creates taste issues and harmful byproducts that approach the legal limit.
The Chlorine Problem
Rochester uses chlorine (not chloramine) for water disinfection. Water is disinfected again as it exits each reservoir before entering the distribution system. While chlorine effectively kills bacteria, it reacts with organic matter in the water to produce disinfection byproducts (DBPs) — specifically trihalomethanes (THMs).
THM Levels in Rochester
Rochester's THM levels have been detected at 81 ppb — just 1 ppb above the EPA maximum contaminant level. This is concerning because THMs are linked to bladder cancer, liver damage, and reproductive issues.
Beyond Bad Taste
Chlorine taste and odor is the most common water complaint. But the real concern is what chlorine creates:
- Bromodichloromethane — linked to cancer and pregnancy complications
- Chloroform — a regulated disinfection byproduct
- Dibromochloromethane — another carcinogenic byproduct
THM levels are typically higher in summer when warmer water temperatures require more chlorine treatment.
The Solution
A whole-house activated carbon filter is the most effective way to remove chlorine and THMs from your entire home:
Removes chlorine, THMs, and taste/odor issues from every tap in your home. Also improves shower water quality for skin and hair.
