The Marin Municipal Water District has been fluoridating its drinking water since December 1973 in response to a voter-approved ballot measure, Local Measure B, which was passed in November 1972. The measure changed the district code by requiring the district to add fluoride to all water served to customers in MMWD's service area. In 1978, another ballot measure, Local Measure D, asked whether MMWD should continue fluoridation of the district’s water supply. A majority of voters said “Yes.” In response, the district continues to fluoridate its water supply.
