The short story is an entrepreneur developed a system which removes some minerals, adds others, and delivers a water said to resemble that of Brooklyn. In south Florida, where the local water is uniformly crappy, this is not an idle accomplishment. Esp to pizza makers, bagel makers, and others.
Also, this being Florida, it also brought franchising, lawsuits, and financial distress:
Greenbaum is suing the Original Brooklyn Water Bagel Co. for more than $2 million in damages, "saying he never would have wanted to develop franchises if he hadn't been duped into believing there was a patented process to "Brooklynize" water." According to his lawyer, "The water filtration system is not unique and does not render water equivalent to Brooklyn water. You want Brooklyn water, go to Brooklyn. You want a Brooklyn bagel, go to Brooklyn."
