DRINKING WATER WARNING Water Outage at AZ0403702 Grand Canyon National Park, Desert View Area
BOIL DESERT VIEW WATER BEFORE USING
Grand Canyon National Park experienced a water outage in the Desert View area at 12:00 a.m. on October 16, 2026, when a pump malfunction reduced pressure in the Desert View water tanks to 5 psi. Only the Desert View area is affected. As a precaution, we are issuing this notice to keep you informed about this potential public health risk, and to provide updates on what we are doing to make the water safe.
Bacterial contamination can occur when increased run-off enters the drinking water source (for example, following heavy rains). It can also happen due to a break in the distribution system (pipes) or a failure in the water treatment process.
What should I do? What does this mean?
DO NOT DRINK THE WATER WITHOUT BOILING IT FIRST. Bring all water to a boil, let it boil for one minute, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice. Boiling kills bacteria and other organisms in the water.
Fecal coliforms and E. coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, and people with severely compromised immune systems.
The symptoms above may also be caused by other things not related to contamination of the drinking water. However, out of an abundance of caution, if you experience any of these symptoms and they persist, you may want to seek medical advice. People at increased risk should seek advice from their health care providers about drinking this water.
What is being done?
Park water operators are on site and continuing to diagnose the pump malfunction. Once the pump is repaired and normal pressure is restored, the Desert View system will be flushed and bacteriological samples will be collected. This boil water advisory will remain in effect until test results confirm the water is safe to drink. We will notify you when the advisory is lifted.
For more information, please contact Adam Leavy, Chief of Facilities & Engineering, at 928-310-8654.
Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
