Bromochloromethane
South Burlington City Water System
NOTE: South Burlington City Water System purchases water from Champlain Water District which is required to test for bromochloromethane. Sample information shown below was taken by Champlain Water District.
Bromochloromethane is a tap water disinfection byproduct; it is also used as an intermediate in chemical manufacturing and as a fire extinguishing agent. Disinfection byproducts in drinking water increase the risk of cancer.
