On April 18th, the SFPUC began adding groundwater from the Westside Aquifer to our Hetch Hetchy drinking water supply. This groundwater has unsafe levels of contaminants and is only minimally treated. It should not be used for drinking.

Tell the SFPUC to stop mixing contaminated groundwater with our good drinking water!

Demand that:

• All San Francisco drinking water must meet or exceed our current Hetch Hetchy water quality.
• Groundwater should not be used for drinking water.
• Use groundwater for irrigation, firefighting, and street cleaning.
• The SFPUC must develop a plan to provide an adequate supply of high-quality drinking water during an emergency until full service is restored.
