City of Daly City Advises Residents to Be Aware of Fraudulent Water Testing Solicitations 

DALY CITY, CA — The City of Daly City is advising residents to be aware of fraudulent phone calls or visits claiming that the City's drinking water is contaminated. 

The City recently received a report from a resident who was contacted by an individual claiming to be a contractor offering to test the resident's water for contamination. The caller suggested they were aware of a contamination issue affecting the property. 

The Department of Water & Wastewater Resources confirms there are no known issues affecting Daly City's drinking water. The City's drinking water continues to meet or exceed all state and federal drinking water quality standards and remains safe for drinking and everyday use. 

Residents should be aware that: 

• The City does not hire contractors to contact residents unsolicited to test drinking water for contamination. 

• If there were a legitimate concern affecting the public water supply, the City would notify impacted customers through official communication channels, such as direct notifications, the City's website, social media, and other emergency notification methods, as appropriate. 

• Residents should exercise caution before providing personal information, allowing unknown individuals onto their property, or purchasing services based on unsolicited claims. 

If you receive a suspicious call or visit regarding your drinking water, the City recommends that you: 

• Decline the unsolicited offer. 

• Verify any claims by contacting the Department of Water & Wastewater Resources directly at (650) 991-8200. 

• Report suspected fraud to your local law enforcement agency if appropriate. 

The City of Daly City is committed to providing safe, reliable drinking water and encourages residents to rely on official City communications for accurate information regarding water quality and public health.
