Q: I grew up drinking from the garden hose all summer. Is that still safe to do?
A: Great question, and one that brings back memories for a lot of us. But here’s the short answer: not really.
It’s a nostalgic question for many people, especially those who spent childhood summers running through sprinklers and taking quick drinks between games of tag. But from a health perspective, drinking from a typical garden hose isn’t considered safe today. Most garden hoses are made from materials that aren’t intended for potable water. That means they may contain chemicals like lead, BPA (bisphenol A) and phthalates, which can leach into the water, especially when the hose is left in the sun or heat. In fact, studies have shown that water sitting in a standard hose can contain levels of lead and other substances far above what’s considered safe for drinking.
Beyond the materials, there’s also the issue of bacteria. Garden hoses often retain water between uses, creating a warm, damp environment that’s ideal for bacterial growth. If the hose doesn’t fully drain or is stored in dirty or hot conditions, the water inside may carry microorganisms that you wouldn’t want to ingest. And because garden hoses aren’t regulated like household plumbing, even water from a clean tap may become unsafe by the time it comes out the other end of the hose.
If you want to drink from a hose, look for one labeled “drinking water safe” or “NSF-certified.” These hoses are made from materials that are tested for safety and don’t leach harmful substances. Flushing the hose before using it can also help, and storing it in a cool, shaded spot can reduce chemical exposure and bacteria buildup. While drinking from the hose may be a cherished summer tradition, it’s worth taking these precautions to make sure it’s not just nostalgic — but also safe.
