[ ] Check water availability and current land-manager or public-health advisories.
[ ] Match documented protection to the expected source and hazards.
[ ] Follow official do-not-drink advisories; do not treat chemical/fuel-contaminated or floodwater as ordinary backcountry water.
[ ] Verify every required container, connector, cartridge and power source.
[ ] Read product-specific operating, cleaning, temperature and storage instructions.
[ ] For chemical treatment, record the exact label dose, contact time and conditions; do not guess.
[ ] For UV treatment, confirm water-clarity, volume, power and full-cycle requirements.
[ ] Keep untreated-water equipment separate from treated-water containers.
[ ] Check product-specific freezing precautions and damage guidance.
[ ] Save the instructions offline before departure.
[ ] Identify a backup safe-water supply, confirmed refill or route-change plan.

Read the full guide for limitations and safety context. A filter or purifier label does not establish that every contaminated source is safe. This is a planning record, not universal treatment instructions. AI-assisted compilation; no product-testing claim.
