Residents in Nevada are advised not to use tap water for drinking, cooking, or brushing teeth until further notice.
A boil water notice has been issued for Nevada following a water system event requiring precautionary action. Local water authorities are urging residents to take immediate precautions while the situation is assessed and resolved. You can track this and all current US notices on our live US boil water notice tracker.
What Is a Boil Water Notice?
A boil water notice is an official public health directive issued when tap water may be unsafe for consumption due to the presence — or potential presence — of harmful pathogens, bacteria, or other contaminants. It is one of the most serious water safety alerts a utility can issue, and compliance is strongly recommended for all affected residents.
Unlike a general water quality advisory, a boil water notice requires immediate behavioural change. Until the notice is lifted by the issuing authority, residents should treat all tap water before use or rely entirely on safe alternative sources.
What Nevada Residents Must Do Right Now
- Boil all tap water — Bring water to a rolling boil for at least one full minute (three minutes if you are above 6,500 feet elevation). Allow it to cool before use.
- Use bottled water — For drinking, making ice, preparing baby formula, and washing produce, commercially bottled water is the safest short-term option.
- Do not brush teeth with tap water — Even a small amount of contaminated water ingested during brushing can cause illness.
- Do not use ice made from tap water — Discard existing ice from your freezer’s ice maker and make fresh ice with boiled or bottled water only.
- Protect your pets — Animals are also vulnerable. Give them boiled or bottled water during the notice period.
- Washing dishes — If hand-washing, use boiled water and allow dishes to fully air dry. Dishwashers that reach 150°F (65°C) or higher are generally considered safe.
- Bathing and showering — Adults may shower, but take care not to swallow water. Avoid bathing young children in tap water during an active notice.
When Will the Notice Be Lifted?
The timeline depends entirely on the underlying cause. Notices triggered by a water main break or pressure loss are often resolved within 24 to 72 hours once repairs are made and water quality testing confirms it is safe. Notices caused by bacterial contamination can take longer, as multiple clean test results are required before authorities lift the order.
Always check the official statement from your local water utility or municipality for updates. You can also monitor our live US boil water notice tracker which we update as notices are issued and cleared across the US.
Nevada Water Quality — Background
Boil water notices like this one highlight why it is important to understand your local water system’s history and vulnerabilities. You can read a full breakdown of on our site, including historical contaminant data, system compliance records, and what the water typically contains between incidents.
For broader context on water quality across Nevada, visit our Nevada water quality overview page. You can also explore our water quality database and the latest water alert news for ongoing coverage of water safety issues nationwide.
A certified water filter can provide protection even during notices caused by bacterial contamination, provided it carries an NSF/ANSI 58 (reverse osmosis) or NSF/ANSI 53 (activated carbon) certification. See our recommended filters for US households — including options from Waterdrop that are independently tested and certified.
Frequently Asked Questions
Is tap water safe to shower in during a boil water notice?
Generally yes for adults, as skin contact with contaminated water does not typically cause illness. However, you must avoid swallowing any water. Young children and infants should not be bathed in tap water during an active boil water notice, and sponge baths with boiled or bottled water are recommended instead.
Can I use a filtered water pitcher instead of boiling?
Standard pitcher filters such as Brita or PUR are not certified to remove bacteria and should not be relied on during a boil water notice. However, reverse osmosis systems certified to NSF/ANSI Standard 58 can remove bacterial contaminants and are generally considered safe alternatives. If in doubt, boil the water.
How do I know when the boil water notice in Nevada has been lifted?
Your local water utility will issue an official notice when the boil water order has been lifted, usually via their website, local news outlets, and automated phone alerts. You can also check our live US boil water notice tracker which is updated as notices are issued and cleared across all states.
