Handbook contents

Drinking water

The landing-page Drinking Water card opens /library-files/family-resources/index.html#drinking-water. Six original PDFs (127 pages) are installed locally: EPA emergency disinfection (September 2017, 2 pages), EPA home testing (May 2005, 2), EPA household wells (24), EPA WaterSense treatment selection (November 2024, 9), Texas rainwater harvesting (third edition 2005, 88), and USU Extension water-storage tips (2). Original editions, contacts, institutional notices and regional scope remain intact.

Coverage and limits

Storage and household sources complement existing FEMA food-and-water, FDA outage and NPS wilderness-treatment references. Rainwater catchment, first-flush systems, cistern sizing and treatment are covered by the Texas manual; its costs, rainfall and legal references are historical and regional. Well sampling and certified-laboratory testing are covered by EPA. Treatment selection is contaminant-specific; boiling or disinfection does not make chemically contaminated water safe. These originals are reference material, not a certification of a particular water source.

The CDC emergency PDF returned HTTP 403 from the Ark and is not represented as installed. EPA provides the installed emergency-disinfection reference. No online-only placeholder card was added.

Configuration and restoration

Sources live in deploy/reference/family-catalogue.json; installed metadata, page counts, sizes and SHA-256 hashes live in /mnt/storage/family-resources/sources.json. Files are under /mnt/storage/family-resources/drinking-water/. The family installer downloads unchanged publisher files, validates PDF headers and page counts, retains verified copies on publisher failure, builds the index and registers assets in the drinking-water repository.

Run /usr/bin/python3 tools/install_family_resources.py --register from /opt/dataark for explicit refresh. Refresh is manual, not a scheduled promise of revised editions. Export intentional library changes with venv/bin/python tools/content_profile.py export. The family restoration recipe checks this repository along with family, food-preservation and sanitation assets before treating the collection as complete. Public configuration and source metadata are mirrored to the SSD recovery kit and saved in GitHub; large PDFs remain on the content drive.

Verification

All six PDFs were parsed with pdfinfo and linked through the local HTTP server. Manifest and content-profile tests cover registration and missing-file restoration behavior.
