When you're out in the wilderness and don't have access to a water source, it can be difficult to find potable water. But with a bit of knowledge and preparation, you can locate a primary source of water and stay hydrated. The best way to find water is to study the topography of your environment. Since water flows downhill, valley bottoms are great places to look for fresh water.
You can also check truck stops, rest areas, and visitor centers for outdoor faucets that provide drinking water. If you're camping, it's a good idea to call a nearby campsite along the way and see if you can fill your water tank. You can also look for birds, as they tend to congregate near water sources. When you do find a source of water, it's important to make sure it's safe to drink.
Boiling the water is the best way to purify it, but if that's not possible, you can leave it in the sun and wait for the water to evaporate and trap the condensation.
