Our water can be safe
for everyone


Join other concerned residents to eliminate harmful and costly chemicals from SF's tap water.

Does our drinking water deserve its good reputation?

We San Franciscans are proud of our tap water. From pure Sierra snowmelt, this water has to be treated for safety, and we trust the City to do its best. 

A growing number of  governmental and non-profit organizations are warning us about the hazardous chemicals in SF's water. 

It is now time to address these concerns and bring our water into the 21st century. Proven alternatives already exist for providing safer drinking water. 

By working together, we can make San Francisco’s water safe for everyone.

At, you can learn the truth about what’s in our water and what you can do to help improve our system through education and leadership.

At-Risk Groups
Many San Franciscans should not drink tap water. This is an alert to the elderly, HIV/AIDS patients, pregnant women and infants, dialysis patients, hypothyroid sufferers, and others.
Business Burden
SF restaurants, cafes and other businesses are forced to choose between paying for expensive filtration to serve safe water or pass on SFPUC's chemicals to their clientele. 
Environmental Racism
African American and Hispanic residents are disproportionately harmed by toxic chemicals present in SF tap water. Visible biomarkers have shown an exponential rise in exposure.  
What Do You Really Know about SF's Drinking Water?
Don't feel bad. Most people don't truly understand our water and the chemistry behind it. 

What are contaminants and what do you need to know about them? 

The San Francisco PUC produces an Annual Quality Report. Read the latest report from 2017 here.

How well do you understand the report? Turbidity? Alkalinity? Byproduct of disinfection? What do these terms mean?

The Center for Disease Control and Prevention says:

Drinking [HFSA] from tap water during the time of birth to age 8 can lead to a disease that causes permanent alterations inside your mouth. In America, this disease is more prevalent among African Americans and Mexican Americans.

Erin Brockovich says:

Adding HFSA to "water supplies...results in uncontrollable doses and ubiquitous contamination of drink and food inorganic chemical characterized by chemists as a poison and labeled as a neurotoxin."

The American Medical Association says:

"It is not feasible to monitor the consumption rate or toxic buildup of [HFSA] in individuals who consume" it in tap water.

United Nations Ambassador Andrew Young says:

"I'm most deeply concerned for poor families who have babies. If they can not afford water free of [HFSA] for their babies' milk formula, do their babies not count? Of course they do. This is an issue of fairness, civil rights, and compassion."

UNESCO’s Bioethics Document, Article 6 (2010) says:

”In no case should a collective community agreement or the consent of a community leader or other authority substitute for an individual’s informed consent.”

Henry Rodriguez, League of United Latin American Citizens (LULAC) says:

"The Hispanic community is no longer going to be silent on this issue. [HFSA] is about forcing us to be medicated through our drinking water without our consent or full disclosure of the risks."

The Union of E.P.A. Scientists says:

"Recent, peer-reviewed toxicity data, when applied to EPA’s standard method for controlling risks from toxic chemicals, require an immediate halt to the use of the nation’s drinking water reservoirs as disposal sites for the toxic waste of the phosphate fertilizer industry."

Senator Mark Leno says:

"It's time San Francisco revisited the [HFSA] issue.I don't want to blow this out of proportion and jeopardize public confidence in our public water supply system. But this is something that should be looked at."

The San Francisco Precautionary Principle Ordinance says:

"Science is also creating new compounds and chemicals that are already finding their way into mother's milk and causing other new problems. New legislation may be required to address these situations."

Dr. Alveda King says:

"This is a civil rights issue. No one should be subjected to drinking [HFSA] in their water."

The National Kidney Foundation says:

"There is consistent evidence that impairment of kidney function results in changes to the way in which [HFSA] is metabolized and eliminated from the body, resulting in an increased burden.... Monitoring of [HFSA] intake...would be prudent for people with stage 4 or 5 chronic kidney disease."

Ed Begley, Jr. says:

"I'm concerned because there are many studies that indicate an association between lowered IQ and levels of [HFSA], which offer no margin of safety to protect all our children, especially low-income families who can not afford avoidance measures."
