Bromate

GENERAL INFORMATION
Bromate is formed when ozone used to disinfect drinking water reacts with naturally occurring bromide found in source water. Bromate formation in disinfected drinking water is influenced by factors such as bromide ion concentration, pH of the source water, the amount of ozone and the reaction time used to disinfect the water.

HEALTH EFFECTS
Some people who drink water of containing bromate in excess of the MCL over many years may have an increased risk of getting cancer.

Contaminant group: 
Inorganic trace constituent
Standard type 1: 
MCL
Action is recommended 1: 

MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Bromate levels were detected in your water sample to exceed the maximum contaminant level (MCL).

Action is optional 1: 

ACTION IS OPTIONAL
Bromate levels were detected in your water sample but do not exceed the maximum contaminant level.

Major sources in drinking water: 
By-product of drinking water disinfection
Treatment options: 

TREATMENT OPTIONS
There are no practical methods currently available to remove bromate from water. Bromate in ozonated drinking-water supplies is best controlled by limiting its formation, which is influenced by the bromide concentration, the source and concentration of organic precursors, pH, temperature, alkalinity and ozone dose.
