The list below shows whether your city in North Dakota uses chlorine or chloramine as the water disinfectant.
The data presented in this table has been verified by Aquatell directly from primary sources, which typically means we located the data in a municipal water quality report or contacted the water utility directly. If your city is not listed, let us know and we will add it right away.
| City | Disinfectant Type | Source |
|---|---|---|
| Bismarck | Chloramine | Source |
| Fargo | Chloramine | Source |
| Grand Forks | Chloramine | Source |
| Minot | Chloramine | Source |
A carbon filter is the right way to remove both chlorine and chloramine, though chloramine reduction requires the use of catalytic carbon. The following are commonly used systems for chlorine and chloramine reduction:
Upflow Catalytic Carbon for Chloramine
Backwashing Carbon for Chlorine
Backwashing Catalytic Carbon for Chloramine
When we talk about Chlorine vs. Chloramine we are really talking about the choice of residual disinfectant, which is the chemical that travels with your water through miles of pipes to reach your tap. Most US cities still use chlorine as their residual, but more are switching to chloramine. Chloramine persists in the water longer. It is a more stable molecule and will not naturally dissipate into the air or aggressively react with every surface it encounters. More persistence means better disinfection coverage from the treatment plant all the way to your home.
But that stability also makes chloramine significantly harder to remove than chlorine. Both compounds are removed using activated carbon filtration, but chloramine removal requires a special type called catalytic carbon. Standard carbon filters designed for chlorine removal will not effectively remove chloramine.
