Chloramine, on the other hand, is a combination of chlorine and ammonia. While chlorine dissipates and evaporates into the air relatively quickly, chloramine is more stable and will last longer in the water system. The goal is to provide increased protection from bacterial contamination.
Chloramine is a combination of chlorine and ammonia. 1  Chloramine is used to disinfect water supplies (like the Hetch Hetchy system.) Water utilities often refer to chloramine as monochloramine. 2  In reality, chloramine exists as three different forms or species: monochloramine (NH2Cl), dichloramine (NHCl2) and trichloramine (NCl3).
