Where does chlorate come from?

The most direct source of exposure to chlorate is Through drinking water that has been disinfected with sodium hypochlorite or chlorine dioxide. The amount of chlorate in drinking water depends on the many chemical reactions in the formation of these disinfectants and the conditions in which they are used.
