Yes---use tap water for ice when it is currently safe to drink where you live and no local water advisory applies. Ice for drinks or food should be made with drinking water. If the water is not approved for consumption, freezing it will not make it safe.
The important distinction is simple: an ice tray, refrigerator dispenser, or countertop ice maker changes water into ice; it does not treat the water. Check current guidance from your local utility or public-health agency if there is an advisory, a private-well concern, or a possible plumbing issue.
When tap water is the right choice
Under normal conditions, tap water is a reasonable choice for ice if all of the following are true:
- Your water is currently approved for drinking.
- There is no boil-water, do-not-drink, or do-not-use advisory in effect.
- You do not have a known household-specific concern that needs follow-up, such as a flooded private well or suspected lead plumbing.
Water utilities and government agencies issue advisories when tap water is, or may be, contaminated with germs, chemicals, toxins, or radioactive materials. The type of advisory determines what you should do, so local instructions matter more than a general rule. CDC guidance on drinking-water advisories
Freezing is not a water-treatment method
Do not freeze questionable water in the hope that the freezer will purify it.
For a microbial emergency, official guidance may call for boiling or another specified disinfection method. But that is not a universal fix: boiling or chemical disinfection does not remove heavy metals, salts, or most other chemicals. In other words, water that is unsafe because of a chemical or toxin concern should not be treated as safe simply because it has been boiled---or frozen. EPA emergency drinking-water guidance
A refrigerator filter also should not be assumed to solve an advisory. Use a filter only when you have verified that its specific model is certified for the contaminant and use case in question---and when local guidance says that approach is appropriate.
What to do during a water advisory
Stop using water-line-connected ice equipment during any drinking-water advisory. That includes refrigerator and freezer ice dispensers, as well as automatic ice makers connected to the household water supply.
Use the advisory label as your starting point:
| Advisory | What to do about ice |
|---|---|
| Boil-water advisory | Discard ice previously made with tap water. Make new ice only with bottled water or water prepared exactly as local officials direct. |
| Do-not-drink advisory | Use commercially bottled water for ice. These notices may involve harmful chemicals or toxins; boiling does not necessarily make the water safe. |
| Do-not-use advisory | Do not use tap water for ice or any other purpose while the advisory remains in effect. |
Local instructions override this table. A boil-water notice may include a specific boiling method and cooling instructions. A do-not-drink or do-not-use notice may identify a different safe water source or additional steps.
For boil-water notices, guidance for ice trays, dispensers, and ice makers is to throw out tap-water ice and make replacement ice with boiled or bottled water. It also advises boiling tap water even if it has passed through a home or pitcher filter. Boil-water notice guidance for ice and connected appliances
Private wells and possible lead plumbing
A public-water advisory is not the only reason to pause before making ice. Some concerns are specific to the home.
If you use a private well
Do not assume a private well is unsafe simply because it is private. But do take local conditions seriously. If a well has been flooded, it should be disinfected and tested after the flood; state or local health departments can advise on the appropriate next steps.
Until you have appropriate guidance or test results for a concern affecting your well, choose a water source that is approved for consumption rather than relying on freezing.
If you have known or suspected lead plumbing
Lead can enter drinking water from lead pipes, including lead service lines, and from brass or bronze faucets and fixtures. That does not mean every older home has a lead problem, nor does it reveal the amount of lead in a particular home's water or ice.
Instead, investigate the service-line material and follow local lead guidance. A utility's service-line inventory can help identify whether a lead service line may be present. If treatment is recommended, use only an option verified for the specific contaminant and intended use. EPA information on lead service lines
Clean equipment, but keep sanitation separate from water safety
Safe source water and clean equipment are two different parts of safe ice-making.
Ice-contact surfaces---including the ice maker, bin, scoop, and reusable trays---need routine cleaning and sanitizing according to the appliance manufacturer's instructions. Ice machines and bins can accumulate unwanted buildup when they are not cleaned on a schedule that prevents it.
After a boil-water advisory is lifted, consult the owner's manual before sanitizing a refrigerator ice maker or countertop machine. Cleaning the appliance helps maintain the equipment, but it does not make unsafe source water safe.
A practical ice-making checklist
Before filling trays or running an ice maker:
- Check whether a local drinking-water advisory is active.
- Use tap water only when it is currently approved for consumption.
- Do not rely on freezing to purify water.
- During a boil-water, do-not-drink, or do-not-use advisory, follow the exact local instructions and stop using connected ice dispensers.
- If you use a private well or suspect lead plumbing, investigate the issue and follow applicable local guidance before relying on the water for ice.
- Clean the ice maker, bin, scoop, or trays as instructed for your specific appliance.
