HOUSEHOLD WATER GUIDE

Is my tap water safe?

No website can certify the water coming from your faucet without a household sample. But you can check current notices, your likely water provider, historical test records, pipe information, and what a home test should focus on.

Start with current instructions

A boil-water or do-not-drink notice matters more than an old record of a water-system issue. IsMyWaterOK checks connected notice sources where available and tells you when today’s status still needs confirmation.

Then check the source and pipes

Utility records describe the water system, while pipes to and inside your home can change what reaches the tap. Lead is the clearest example of why both layers matter.

Test only when it adds new evidence

A home test is most useful when it answers something public records cannot: what is actually in water collected from your faucet or private well.
