Many Counties in Texas have switched to Chloramines in the water supply
- Chloramine is a combination of chlorine and ammonia.
- Chloramine is used to disinfect water supplies. Water utilities often refer to chloramine as monochloramine.
- In reality, chloramine exist as three different forms of species: monochloramine, dichloramine and trichloramine. They are chemically related and are easily converted into each other; thus, they are more appropriately called Chloramines.
- The three species of chloramine constantly and rapidly shift from one form to another. The species that predominates is dependent on pH, temperature, turbulence and the chlorine to ammonia ratio.
- Even time plays a factor because after a day or so, with no changes in conditions, monochloramine in a water system will slowly degrade to form dichloramine and some trichloramine.
- Chloramines are all respiratory irritants with trichloramine being the most toxic.
- In contrast to what water utilities claim, it is impossible to have only monochloramine. It is not unusual in water systems for harmful di and trichloramines to occur.
- Trihalomethanes (THMs) are disinfection byproducts that are formed when organic matter in the water combines with chlorine.
- THMs are also formed with chloramine disinfection but at a lower concentration – (approximately 1/3 less) than chlorine.
- THMs are possible but no proven cancer causing byproducts.
