Definitions for "Drinking Water"
When teens are not near a potable water source, they fill water bottles at streams, springs, or other natural water sources. Iodine tablets are used to purify the water for safe drinking. Staying hydrated is vital in the backcountry, so we fill up every chance we get. Each participant carries at least two quart-size water bottles.
There are two major sources of drinking water: surface water and groundwater. Surface water comes from lakes, reservoirs and rivers, while groundwater comes from wells that the water supplier drills into aquifers. An aquifer is an underground geologic formation through which water flows slowly. Most large cities in the United States use surface water, and most small towns use groundwater.
