At lds.org, provident living, we are instructed to:
Store drinking water for circumstances in which the water supply may be polluted or disrupted.
If water comes directly from a good, pretreated source, then no additional purification is needed; otherwise, pretreat water before use. Store water in sturdy, leak-proof, breakage-resistant containers. Consider using plastic bottles commonly used for juices and soft drinks.
Keep water containers away from heat sources and direct sunlight.
