In 1989–1990, several students circulated a dihydrogen monoxide contamination warning on the University of California, Santa Cruz, campus via photocopied fliers.
In 1994, Craig Jackson created a web page for the Coalition to Ban DHMO.
The Friends of Hydrogen Hydroxide website was created by Dan Curtis Johnson, partly as a foil on the Coalition page, claiming to oppose its "subversive agenda". The site points out that hydrogen hydroxide is "environmentally safe" and "enhances the functionality, growth, and health of many forms of life".
In 1997, Nathan Zohner, a 14-year-old student at Eagle Rock Junior High School in Idaho Falls, Idaho, gathered 43 votes to ban the chemical, out of 50 ninth-graders surveyed. Zohner received the first prize at Greater Idaho Falls Science Fair for analysis of the results of his survey. In recognition of his experiment, journalist James K. Glassman coined the term "Zohnerism" to refer to "the use of a true fact to lead a scientifically and mathematically ignorant public to a false conclusion".
In late 1997, drawing inspiration from Jackson's web page and Zohner's research, Tom Way created a website at DHMO.org, including links to some legitimate sites such as the Environmental Protection Agency and National Institutes of Health.
On April 1, 1998 (April Fools' Day), a member of the Australian Parliament announced a campaign to ban dihydrogen monoxide internationally.
In 2001, a staffer in New Zealand Green Party MP Sue Kedgley's office responded to a request for support for a campaign to ban dihydrogen monoxide by saying she was "absolutely supportive of the campaign to ban this toxic substance". This was criticized in a press release by the National Party, one of whose MPs fell for the very same joke six years later.
In 2002, radio talk show host Neal Boortz mentioned on the air that the Atlanta water system had been checked and found to be contaminated with dihydrogen monoxide, and set about relating the hazards associated with that "dangerous" chemical. A local TV station even covered the 'scandal'. A spokesperson for the city's water system told the reporter that there was no more dihydrogen monoxide in the system than what was allowed under the law.
The idea was used for a segment of an episode of the Penn & Teller documentary show Penn & Teller: Bullshit!, in which actress Kris McGaha and a camera crew gathered signatures from people considering themselves "concerned environmentalists" to sign a petition to ban DHMO.
In March 2004, Aliso Viejo, California, almost considered banning the use of foam containers at city-sponsored events because dihydrogen monoxide is part of their production. A paralegal had asked the city council to put it on the agenda; he later attributed it to poor research. The bill was pulled from the agenda before it could come to a vote, but not before the city received a raft of bad publicity.
In 2006, in Louisville, Kentucky, David Karem, executive director of the Waterfront Development Corporation, a public body that operates Waterfront Park, wished to deter bathers from using a large public fountain. "Counting on a lack of understanding about water's chemical makeup", he arranged for signs reading: "DANGER! – WATER CONTAINS HIGH LEVELS OF HYDROGEN – KEEP OUT" to be posted on the fountain at public expense.
In 2007, Jacqui Dean, New Zealand National Party MP, fell for the joke, writing a letter to Associate Minister of Health Jim Anderton asking "Does the Expert Advisory Committee on Drugs have a view on the banning of this drug?"
On April 1, 2009, then-Canadian Member of Parliament, Andrew Scheer (who was later elected leader of the Conservative Party), used the DHMO parody as the basis for an April Fool's Day "media release" on his website, in which he claimed to have presented a bill to ban the substance from all federal government buildings.
In February 2011, during the campaign of the Finnish parliamentary election, a voting advice application asked the candidates whether the availability of "hydric acid, also known as dihydrogen monoxide" should be restricted. 49% of the candidates answered in favor of the restriction.
In April 2013, as part of an April Fools' Day prank, two radio personalities at Gator Country 101.9, a station in Lee County, Florida, were suspended for a few days after telling listeners that dihydrogen monoxide was coming out of their water taps. The prank resulted in several calls by consumers to the local utility company, necessitating that the company send out a press release stating that the water was safe.
In May 2018, a noticeboard in Wuling Farm warned visitors that they were "using dihydrogen monoxide" (to make it look like using a pesticide) at the apple tree farms to prevent theft.
