Chloroform evaporation rate
Chloroform is known to form as a by-product of water chlorination, along with a range of other disinfection by-products, and as such is commonly present in municipal tap water and swimming pools. Reported ranges vary considerably but are generally below the current health standard for total trihalomethanes of 100μg/L. Nonetheless, the presence of chloroform in drinking water at any concentration is considered controversial by some.
