I was reading an article from Reuters and it made me wonder about bromate in our tanks (for those that use ozone)
Here are a few quotes from the article:

Here are a few quotes from the article:
The Coca-Cola Co said on Friday it had recalled its entire Dasani range of bottled water from the British market after levels of bromate, a potentially harmful chemical, were found to exceed legal standards.
"Bromate is a chemical that could cause an increased cancer risk as a result of long-term exposure, although there is no immediate risk to public health," the agency said in a statement.
British limits for bromate, a non-metallic salt, in bottled and tap waters are 10 parts per billion, a Coca-Cola spokesman said, and the Dasani samples had tested at between "borderline" (about 10) and 22 parts per billion. European tap water limits are 25 parts per billion.
When we use ozone on our tanks, is the formation of bromate a concern?Coca-Cola said the bromate was formed during the ozone gas purification process it used in Dasani manufacturing and bottling. To ensure that Dasani meets calcium levels required in all UK bottled water products, it adds calcium chloride, a derivative of bromide. But due to the amount of bromide in the water, the ozonization process caused bromate to form at unacceptable levels, Coca Cola said. Ozonization is a popular process in the bottled water industry, as the ozone gas bubbled through the water kills microorganisms, dissipates quickly and leaves no aftertaste, unlike chlorine treatment.
