Find water in dry country
Water moves down and collects predictably — read the terrain first, then walk.
1. Head to the lowest ground: canyon bottoms, dry washes, the outside bends of dry riverbeds.
2. Dig at the base of cliff pour-offs and in shaded gravel bars — seep water rises in minutes.
3. Follow converging animal trails downhill; they braid toward water.
4. Watch for green vegetation (cottonwood, willow, cattail) standing out from the surroundings.
5. At dawn, look for insects, especially bees — most fly within a mile of water.
Warning: Always purify seep and puddle water; livestock and wildlife share the same holes.

Purify water by boiling
A rolling boil kills every waterborne pathogen you'll meet in the field.
1. Pre-filter through a bandana or shirt to remove silt and debris.
2. Bring the water to a full rolling boil — bubbles across the whole surface, not just the sides.
3. Hold the rolling boil for 1 minute (3 minutes above 6,500 ft / 2,000 m).
4. Cover and cool. Pour between two containers to reoxygenate and improve taste.
Tip: No pot? Boil in a birch bark cone or a hollowed log with rocks heated in the fire.

Build a three-layer ground filter
A field filter clears silt and cuts pathogens — it doesn't replace boiling.
1. Cut the bottom off a bottle (or use a bark cone) and invert it over a catch vessel.
2. Bottom layer: coarse pebbles, two fingers deep.
3. Middle layer: clean sand, three fingers deep.
4. Top layer: crushed charcoal from your fire, three fingers deep.
5. Pour cloudy water in slowly; the first pass may run dirty — recycle until clear.
6. Boil the filtered output before drinking.
Warning: Charcoal only — never ash. Ash makes the water caustic.

Collect dew with a bandana
Dew off unpoisoned grass gives you a cup or two before sunrise.
1. Before dawn, tie a clean bandana or shirt around your calves.
2. Walk slowly through tall, ungrazed grass until the cloth is soaked.
3. Wring the cloth into a container. Repeat until sun burns off the dew.
4. Purify before drinking — dew picks up whatever's on the plants.
Warning: Skip grass near roads, farmland, or animal droppings.

Solar still basics
A solar still gives small amounts of clean water at a large cost of sweat.
1. Dig a pit two feet wide and a foot deep in a sunny spot with damp soil or green vegetation.
2. Place a container in the center; line the pit with green plants around it.
3. Cover the pit with a clear plastic sheet and seal the edges with soil.
4. Set a small stone on the plastic directly over the container to form a low point.
5. Water condenses on the underside, runs to the low point, and drips into the container.
Tip: Yield is small — a still is a supplement, not a plan. Dig it only if you're already staying put.

Purify water with unscented household bleach
Regular 5–6% sodium hypochlorite bleach is a WHO-recognized emergency water treatment when you have no filter or fire.
1. Filter cloudy water through cloth or let it settle until reasonably clear.
2. Add 2 drops of unscented 5–6% household bleach per liter of clear water; use 4 drops per liter if the water is cold or still turbid.
3. Stir and let stand for at least 30 minutes.
4. The water should have a slight chlorine smell. If not, repeat the dose and wait another 15 minutes.
5. If chlorine taste is too strong, pour between two clean containers a few times to aerate before drinking.
Warning: Never use scented, color-safe, or additive bleach. Bleach does not reliably kill Cryptosporidium — boil or filter when parasites are a concern.

Melt snow and ice for drinking water
Snow is 90% air. Melting it wrong wastes fuel, scorches your pot, and can trigger cold injuries.
1. Start with a small amount of liquid water in the pot — even a couple of ounces — before adding snow.
2. Add snow gradually, stirring so the ice contacts water rather than dry pot metal.
3. Prefer ice or hard, dense snow over fresh powder — you get four times more water per volume.
4. Bring to a rolling boil for 1 minute (3 minutes above 6,500 ft) before drinking to kill pathogens from animal fecal contamination.
5. Insulate the pot and store extra water in bottles kept close to your body so it doesn't refreeze.
Warning: Never eat snow directly for hydration — it drops your core temperature and burns calories your body cannot afford to lose.

Collect water with a transpiration bag
A clear plastic bag tied around a leafy branch on a sunny day can yield a cup or more of drinkable water.
1. Pick a non-toxic, leafy branch of a healthy tree in direct sun — birch, maple, and most conifers work well.
2. Slip a clean, clear plastic bag over as much foliage as possible and tie the mouth tightly around the branch.
3. Angle a low corner of the bag downward so water collected during transpiration pools in one spot.
4. Leave for 3–5 hours in strong sun; a mature branch can produce a half-cup to a full cup of water.
5. Drink directly or filter through cloth if debris got into the bag.
Warning: Never use this on toxic species (oleander, yew, poison ivy, poison sumac). If you can't identify the tree, don't drink the water.

Dig a gypsy well beside stagnant water
A hole dug next to a stagnant pond fills with pre-filtered water through the soil layer — much cleaner than the pond itself.
1. Choose a spot 3–5 feet back from the water's edge on the uphill side if possible.
2. Dig a hole about a foot across and deep enough that the bottom sits below the pond's waterline.
3. Let the first fill of muddy water seep in and bail it out completely — repeat 2–3 times.
4. Once the well refills with clearer water, scoop it gently to avoid stirring up sediment.
5. Still filter and boil or chemically treat before drinking — a gypsy well removes debris, not pathogens.
Tip: Line the sides with sticks or rocks to keep the walls from collapsing back into your water source.

5 min
Adjust water boil time for altitude
Water boils at lower temperatures at high altitude, so you need longer boil times to reliably kill pathogens.
1. Below 6,500 feet (2,000 m): a rolling boil for 1 minute kills all common waterborne pathogens.
2. Above 6,500 feet: extend to a full 3 minutes at a rolling boil.
3. Do not rely on 'just to a boil' at any elevation — the water must maintain a full rolling boil for the timed interval.
4. For extra confidence in remote alpine environments, use both a filter and a boil.
5. Filter cloudy water through cloth before boiling so heat doesn't waste on sediment.
Warning: Boiling does not remove chemical contamination — heavy metals, salts, and industrial pollutants stay in the water. Only pathogens die.

Boil water in a plastic bottle over coals
Water inside a plastic bottle protects the plastic from melting long enough to bring the water to a boil — a genuine emergency trick.
1. Fill a clear plastic bottle (PET, like a common soda or water bottle) completely full — no air gap.
2. Set the bottle upright directly on hot coals raked to the edge of the fire, not in active flame.
3. Turn the bottle a quarter-turn every 30 seconds so it heats evenly.
4. The water will reach a boil while the bottle scorches on the outside; contents remain drinkable.
5. Handle with sticks or a bandana — the bottle is soft and hot; let it cool before pouring.
Warning: Emergency use only. Repeated heating of plastic bottles releases chemicals into the water. Use once, then discard the bottle.

Drink from a water vine
In tropical forests, some woody vines carry drinkable water straight from the ground to the canopy.
1. Look for thick, woody lianas or grape vines climbing from the forest floor into the canopy.
2. Cut the vine high with a knife and let the cut end drip into your mouth or container.
3. If no water flows, the vine may be dead or the flow reversed — try cutting lower down or choose another vine.
4. Collect only what you need; vines are a limited resource and animals depend on them too.
5. Filter through cloth and purify if possible, especially near human or livestock activity.
Warning: Some vines exude milky latex that is toxic or irritating. If the sap is white and sticky, don't drink — pick a different vine.
