War I, company founder Halsey W. Taylor invented the "Double Bubbler" drinking fountain. This fountain dispensed two streams of water in an arc. Several years later the Bubbler adopted this more sanitary arc projection, which also allowed the user to drink more easily from it. At the start of the 20th century, it was discovered that the original vertical design was related to the spread of contagious diseases. In the United States, segregation of public facilities including but not limited to water fountains due to race, color, religion, or national origin was abolished by the Civil Rights Act of 1964. Prior to this, racially segregated water fountains with those for black people in worse condition than those for white people were common. Cleanliness In recent studies, it has been found that some drinking fountains have been contaminated with pathogens such as bacteria. In one study, a virus commonly known to cause diarrhea in young children, known as the rotavirus, has been found on drinking fountains in child day care facilities. Due to cases in the past where children have fallen ill due to coliform bacteria poisoning, many governments have placed strict regulations on drinking fountain designs. The vertical spout design is now illegal in most US jurisdictions. Some governments even require water spouts to be as long as four inches to meet health standards. It is also recommended for young children to allow drinking fountains to run before drinking, as the water may also be contaminated with lead. This is especially common in older buildings with obsolete plumbing. In the 1970s, this fear of contamination in tap water was hyped by producers of bottled water, thereby changing attitudes to publicly provided water in drinking fountains, which began to disappear from city streets. Terminology The term bubbler is used in some regional dialects of the United States and in Australia. A survey of US dialects undertaken between 2002 and 2004 found the word bubbler is commonly used in southern and eastern Wisconsin and in Massachusetts and Rhode Island. The phrase drinking fountain was common in the rest of the inland north and in the west, while water fountain dominated other parts of the country. The term bubbler is sometimes used in the Portland, Oregon, region where in the early 1900s former Wisconsin resident Simon Benson installed 20 fountains, which are now known in the Portland area as "Benson Bubblers".
