Per the link above, Dow promises that the Food Grade products will have the historical bromide levels. (Item 3)
For the Technical Grade (Dowflake and other deicers), they say the bromide will usually be at historical levels but may be as high as the new level. (Item 2)
That probably means that they will be doing some test runs of their processing with the bromine extraction process turned off. So you'll probably get 65 ppm but you might get 8000 ppm. That doesn't make me feel all warm and fuzzy.
