You need to stay hydrated — that’s clear — but is the tap water in your home safe? It is considered generally safe if it comes from a public water system in the United States, such as one run and maintained by a municipality. The Environmental Protection Agency (EPA) has the authority to monitor all public water systems and sets enforceable health standards regarding the contaminants in drinking water.
When drinking water leaves a treatment plant on its way to your house, it must meet strict safety standards. That doesn’t mean that your water is free of all contaminants, but that the levels of any contaminants don’t pose any serious health risk.
Of course, accidents can happen. If the water supply becomes contaminated by something that can cause immediate illness, the supplier must promptly inform you. Suppliers also need to offer alternative suggestions for safe drinking water. In addition, they have 24 hours to inform customers of any violation of standards that could have major impact on health following a short-term exposure.
