The Water Data Card is where it all started. Each rigid card is a field-ready repository of water-treatment knowledge — treatment methods, dosing by container size, sterilization steps, and common conversions — built to give you the right information at the moment you need it, no phone or signal required. When the difference between safe and unsafe water comes down to getting the dose right, a Water Data Card takes the guesswork out of it.

Cana Provisions carries the full line: single cards for specific containers and treatment methods, plus curated kits that build out your reference library. Start with the Core Kit for the essentials, step up to the Master Kit for the complete set, or fill gaps with the Expansion Kit — including dedicated cards for chemical disinfection, and more. Rugged, water-ready, and made in the USA, Water Data Cards are the foundation of a well-built water plan.
