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.
Some people who drink water of containing bromate in excess of the MCL over many years may have an increased risk of getting cancer.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Bromate levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Bromate levels were detected in your water sample but do not exceed the maximum contaminant level.
