Mountain View Boil Water Advisory Extended After Bacteria Detection

The Mountain View boil water advisory remains in effect after coliform bacteria were detected in the water supply. Officials say residents must continue boiling tap water before drinking or cooking.

What Happened and Which Areas Are Affected?

City officials confirmed the issue impacts 23 homes, primarily along Drucilla Drive and Carla Court. The contamination began on April 24 when construction work allowed cement slurry into a drinking water pipeline.

While tests detected coliform bacteria, authorities stressed that E. coli was not found, reducing the immediate health risk but still requiring precaution.

Is the Water Safe to Use?

Residents can use tap water for cleaning, bathing, and other household tasks. However, drinking water must be boiled until further notice to ensure safety.

When Will the Advisory Be Lifted?

Officials do not expect the advisory to end before May 9–10, as crews continue testing and treatment efforts. A “super chlorination” process is underway to fully disinfect the affected pipeline.

What Are Officials Doing Now?

City crews are actively flushing the system, monitoring water quality, and working to restore normal conditions. Officials emphasized that public health remains the top priority.

For now, residents are urged to follow all safety guidelines as testing continues and updates are expected later this week.
