About 40 years ago, researchers became aware of a chemical byproduct from water being treated with chloramine, but only with new testing have researchers been able to identify exactly what it is.
Chloramination is the treatment of drinking water with a chloramine disinfectant. [1] Both chlorine and small amounts of ammonia are added to the water one at a time which react together to form chloramine (also called combined chlorine), a long lasting disinfectant.
The chloronitramide anion was first detected as a UV absorbance interference during monitoring of chloramine and dichloramine in 1981. [6] It was then shown to form during the decomposition of both chemicals. [6] It was shown to likely be an anion in 1990. [7]
Due to its acidic nature, adding chloramine to the water supply may increase exposure to lead in drinking water, especially in areas with older housing; this exposure can result in increased lead levels in the bloodstream, which may pose a significant health risk. Fortunately, water treatment plants can add caustic chemicals at the plant which ...
The Safe Drinking Water Act, which was passed by Congress in 1974, regulates the country’s drinking water supply, focusing on waters that are or could be used for drinking. This act requires ...
Many hundreds of DBPs exist in treated drinking water and at least 600 have been identified. [1] [7] The low levels of many of these DBPs, coupled with the analytical costs in testing water samples for them, means that in practice only a handful of DBPs are actually monitored. Increasingly it is recognized that the genotoxicities and ...
