    To me it's weird that it's not common knowledge.

    St. Patrick's Day[edit]

    As part of a more than fifty-year-old Chicago tradition, the Chicago River is dyed green in observance of St. Patrick's Day.[77] The actual event does not necessarily occur on St. Patrick's Day and is scheduled for the Saturday before March 17, unless the 17th falls on a Saturday (when the event takes place on St. Patrick's Day).

    The tradition of dyeing the river green arose by accident when plumbers used fluorescein dye to trace sources of illegal pollution discharges.[78]The dyeing of the river is still sponsored by the local plumbers union.[79]

    The Environmental Protection Agency (EPA) outlawed the use of fluorescein for this purpose, since it was shown to be harmful to the river.[78]The parade committee has since switched to a mix involving forty pounds of powdered vegetable dye.[80] Though the committee closely guards the exact formula, they insist that it has been tested and verified safe for the environment.[81] Furthermore, since the environmental organization Friends of the Chicago River believes the dye is probably not harmful, they do not oppose the practice.[82]

    In 2009 First Lady Michelle Obama, a Chicago native, requested that the White House fountains be dyed green to celebrate St. Patrick's Day
