As chloroform is a volatile organic compound, [18] it dissipates readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow.
James Young Simpson (great nephew) Sir James Young Simpson, 1st Baronet FRSE FRCPE FSA Scot (7 June 1811 – 6 May 1870) was a Scottish obstetrician and a significant figure in the history of medicine. He was the first physician to demonstrate the anaesthetic properties of chloroform in humans and helped to popularize its use in medicine. [1][2]
Trihalomethanes were the subject of the first drinking water regulations issued after passage of the U.S. Safe Drinking Water Act in 1974. [ 5 ] The EPA limits the total concentration of the four chief constituents ( chloroform , bromoform , bromodichloromethane , and dibromochloromethane ), referred to as total trihalomethanes (TTHM), to 80 ...
In addition to being highly influenced by the types of organic and inorganic matter in the source water, the different species and concentrations of DBPs vary according to the type of disinfectant used, the dose of disinfectant, the concentration of natural organic matter and bromide/iodide, the time since dosing (i.e. water age), temperature ...

Potential sources of well water contamination. Approximately 13 million households in the US get their drinking water from privately owned wells. [104] Private wells are not regulated by EPA. [18] In general, private well owners are responsible for testing their wells, and some states provide guidance and technical assistance on testing. [105 ...
Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds containing at least one covalently bonded atom of chlorine. The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) includes common examples. The wide structural variety and divergent chemical ...
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic.
