The Chicago River is dyed green to celebrate St. Patrick's Day each year. The tradition dates back to 1962 when the Chicago Journeymen Plumbers Local Union dumped 100 pounds of bright green dye into the river. The dye was originally used to detect leaks and pollution in the river, but it was adopted as a way to celebrate the city's Irish heritage. Today, the Chicago Plumbers Local Union still dyes the river using a secret formula that is believed to be an orange-red, vegetable-based powder. The process typically involves two boats, one for dumping the dye and another for stirring it, and about 40 pounds of dye to turn the river a vibrant shade of green.

The Chicago Journeymen Plumbers Union dyes the river green
The Chicago Journeymen Plumbers Union Local 130 has been dyeing the Chicago River green since 1962. The tradition began when, in 1961, Stephen Bailey, the business manager of the union, noticed emerald green stains on a plumber's overalls. The stains were caused by a dye used to find leaks and pollution in the river. As Bailey was also the chairman of the city's St. Patrick's Day parade, he suggested using the dye to turn the river green.
The next year, with the approval of Mayor Richard J. Daley, the union used 100 pounds of the same dye to stain the Chicago River green for St. Patrick's Day. The bright, fluorescent hue honours Ireland's nickname, the Emerald Isle. The original dye was toxic, and in 1966, environmentalists convinced the city to adopt a formula made from vegetables. The recipe is a closely guarded secret, but it is known to be an orange-red powder that turns green in the river.
The process of dyeing the river involves two boats, each featuring relatives of the first families to dye the river. One boat dumps the dye, and the other stirs the water to create the nearly neon green hue. The boats cover a quarter-mile stretch of the waterway, from Columbus Drive to State Street or Orleans Street. The river remains green for several hours, with the colour starting to fade in the late afternoon.
The Chicago Journeymen Plumbers Union still manages the dyeing process each year, and it has become a beloved tradition in the city. Thousands of onlookers gather to watch the river being dyed, and the event is considered one of the biggest parties of the year in Chicago.

The dye is an orange-red, vegetable-based powder
The dyeing of the Chicago River green is a tradition that dates back to 1962. The exact formula of the dye is a closely guarded secret, but it is known that it is an orange-red, vegetable-based powder. This powder is turned into a dye and dumped into the river by the Chicago Journeymen Plumbers Union, who also stir it into the water. The process typically involves two boats and six plumbers, who work together to transform the river into a vibrant shade of green.
The original idea for dyeing the river is attributed to Stephen Bailey, the business manager of the Chicago Journeymen Plumbers Local Union, who noticed the bright green stains on a plumber's overalls caused by a dye used to find leaks and pollution in the river. Bailey, who was also the city's St. Patrick's Day parade chairman, suggested using this dye to turn the river green. With the approval of Mayor Richard J. Daley, the union dumped 100 pounds of the dye into the river in 1962, turning it green for an entire week.
Over the years, the union has perfected its formula, and now only 40 pounds of dye are needed to turn the river green for a few hours. The process typically takes place on a Saturday on or before St. Patrick's Day, when the city's St. Patrick's Day parade is held. The river is dyed between Columbus Drive and Orleans Street or State Street, and the best views can be seen from the Chicago Riverwalk or Upper Wacker Drive.
While the exact ingredients of the dye remain a secret, it is known that it is safe for the ecosystem and poses no risk to the wildlife. The city of Chicago has stated that the dye used today meets the minimum health requirements for chemicals added to drinking water and has caused no negative effects. The tradition of dyeing the river green is a beloved part of Chicago's St. Patrick's Day celebrations and attracts thousands of onlookers each year.

The tradition began in 1962
The tradition of dyeing the Chicago River green began in 1962. The story goes that in 1961, Stephen Bailey, the business manager of the Chicago Journeymen Plumbers Local 130, noticed emerald green stains on a plumber's overalls. These fluorescent stains were caused by a dye used to find leaks and pollution in the river. The river was in a poor state, having previously been used as a dumping ground for the city's slaughterhouses. Bailey, who was also the chairman of the city's St. Patrick's Day Parade, suggested using the dye to turn the river green.
The next year, with the approval of Mayor Richard J. Daley, the Chicago Journeymen Plumbers Local Union used 100 pounds of the same dye to stain the Chicago River green for St. Patrick's Day. The bright, emerald green hue honours Ireland's nickname, the Emerald Isle. The original dye was chemical-laden and caused environmental concerns, so in 1966, environmentalists convinced the city to adopt a vegetable-based formula. The recipe is a closely guarded secret, but it is known to be an orange powder that turns green in the water.
The tradition has continued annually, with the river being dyed in the days leading up to the St. Patrick's Day Parade. The process involves two boats, each with members of the original families who started the tradition. One boat dumps the dye, and the other stirs it up. The Chicago River remains a popular attraction for St. Patrick's Day celebrations, with thousands of people flocking to see the river dyed green.

The river is dyed for St. Patrick's Day celebrations
The tradition of dyeing the Chicago River green began in 1962 when the Chicago Journeymen Plumbers Local Union dumped around 100 pounds of bright green dye into the river. The dye was originally used to detect leaks and pollution in the river, but it was also the perfect colour to represent Ireland, the Emerald Isle. The river remained green for an entire week that year. Today, the Chicago Plumbers Local Union 130 uses just 40 pounds of dye, and the green colour lasts for several hours.
The process involves two boats, one to dump the dye and another to stir it. The dye is an orange-red or orange vegetable-based powder that turns the river a vibrant shade of green. The exact formula is a closely guarded secret. The best views of the green river can be seen from the Chicago Riverwalk in the morning or early afternoon, and on Upper Wacker Drive.
The river dyeing has become one of the most famous St. Patrick's Day traditions in the US, with thousands of people flocking to see it. While it is a well-loved tradition, there have been concerns over the years about the environmental impact of the dye. The original toxic formula has since been replaced with a vegetable-based powder that is considered safe for the ecosystem.
