MMWD Board hands are NOT tied!

Is it legal to put an initiative on the ballot in Marin County to vote for the forced medication of the population via our drinking water? The fluoride compound used in our water is Hydrofluorosilicic acid and it is NOT approved by the FDA for human consumption.  The reason this industrial grade fluoride compound is put into our water is to have a medical effect on our bodies.  This is put into our water without dosage control (once you put it in the water, you can not control the dosage), without individual consent, without medical oversight, and often without people's knowledge.  The water fluoridation ordinance that was passed as a result of the 1972 and 1978 votes goes against Federal Law and the US Constitution.  This is an issue that legally should NEVER have been put on the ballot. The medicating of the population via our drinking water is not something that can be put up for a vote.  It is our legal right to choose for ourselves what medications we wish to imbibe.  

According to the Marin Board of Supervisors, the MMWD are allowed to put whatever they want into our municipal drinking water without any oversight!  They are adding to our water an industrial grade fluoride compound that is not approved by the FDA.  The MMWD tells us it is approved by the NSF.  The NSF does not have the authority to approve chemical substances that are being used to have a medical effect on the body.  The NSF approves chemicals for the treatment of water.  Hydrofluorosilicic acid is not being used to treat the water, it is being used to have a medical effect on the body.  
 
Finally, has the MMWD done studies on the effect of mixing HFA with chloramines?  Because HFA corrodes pipes, the MMWD adds baking soda to prevent this.  The combo of HFA, baking soda and chloramines I believe is NOT good.
