Chloramine was first implemented in Denver in 1917, and today, one in five Americans receives drinking water from systems using chloramination. Other cities using this safe, effective disinfection process include:

  • Philadelphia
  • Washington, D.C.
  • Boston
  • San Francisco
  • Dallas
  • Indianapolis
  • St. Louis
  • Houston
  • Milwaukee
