Do I need to treat water from wells or springs?

Assessing the Risk

When it comes to wells or springs in the backcountry, it’s essential to assess the risk of contamination. This may involve evaluating the water source’s proximity to animal habitats, agricultural runoff, or human settlements. A general rule of thumb is to treat water from wells or springs with a history of contamination or those located in areas with potential pollution sources.

Water Treatment Methods

There are several methods for treating water from wells or springs, including boiling, disinfecting with iodine or chlorine, and using water filters. Boiling is the most effective method, but it requires equipment and fuel. Disinfecting with iodine or chlorine tablets is a more convenient option, but it may not remove particulate contaminants. For example, a 16-ounce water bottle with 16 drops of unscented chlorine bleach can effectively disinfect water when mixed and allowed to stand for 30 minutes. Water filters, such as those with a porosity of 0.2 microns, can remove particulate contaminants but may not remove all bacteria or viruses.

Portable Water Treatment Options

Portable water treatment options are essential for backcountry travelers. A portable water filter, such as the Sawyer Mini, can weigh as little as 2 ounces and provide effective filtration for a single person. Other options include water purification tablets, like AquaSafe, which can disinfect 1 liter of water in 15 minutes. When selecting a portable water treatment option, consider factors such as weight, portability, and effectiveness against a range of contaminants.
