Ready.gov (opens in a new tab)
FEMA
The federal baseline for household preparedness, in more than ten languages. Start here before you buy anything. The checklists are conservative and free, which is the right combination for a first plan.

Build a kit (opens in a new tab)
FEMA
The federal kit list. Treat it as a floor rather than a target: it is deliberately generic, so it under-specifies for cold climates and says little about medication.

Making water safe in an emergency (opens in a new tab)
CDC
Boiling times, bleach ratios and what disinfection does not fix. The chemical ratios here are the ones to trust, because most of the numbers circulating online are copied from older guidance.
- Government or standards bodyGovernment agencyFree
Ground water and drinking water (opens in a new tab)
EPA
Standards, contaminant limits and how to read a water quality report. Useful when you want to know what a filter claim means rather than what the box says.

Cooperative Extension System (opens in a new tab)
USDA NIFA
Find your state extension office. Extension publications are the most under-used preparedness resource in the country: tested, local, free, and written by people who answer the phone.

Live stream gauges and groundwater levels. Useful for flood watching and for understanding whether the creek you were counting on runs year round.

US Drought Monitor (opens in a new tab)

Reddit
The largest general preparedness forum, and more practical than its reputation suggests. Sort by top of the month rather than reading the front page, which skews toward news reaction.
