“Everywhere we go in wilderness areas, there’s potential for contamination,” says Dr. William Forgey, a resident of Crown Point, Ind., and former president of the Wilderness Medical Society. But a little care and preparation can make grabbing a drink in the backwoods safe and simple.
Boiling water eliminates bacteria, viruses, and germs. “Once you bring it to a boil, you’ve done it,” Forgey says. Heating water to at least 150 degrees takes care of most diseases. The process won’t eliminate chemicals, though, such as those from fertilizers. But boiling is often troublesome, and there are quicker ways to purify water.
Iodine, sold in many outdoor-supply stores, is an option. The chemical works well against most viruses and bacteria. But treating water with iodine might not suit everyone’s tastes. “It tastes a little like a swimming pool,” Forgey says.
Technology offers a solution. Small, lightweight filtration systems can fit in a small pack and will clear water of most contaminants. Water is pumped through a series of filters and screens to remove bacteria and viruses. As a bonus, chemicals are often caught and removed.
Prices range from $40 to $250. Less expensive products work, but may not remove small bacteria like the fine screens in higher priced models. Your gastrointestinal system may be grateful you made the investment.
