It&#x27;s also &quot;probably good enough&quot; to use your tap water.<p>The one place we know it isn&#x27;t safe - Flint - says that you should not use tap water for cooking as the lead will get in the food.<p>Nor does it make sense to diversify sources. You pay a lot more for non-tap water, bottled water doesn&#x27;t have a track record of being better than tap water, and it&#x27;s harder to track any recall issues or other warnings if you have multiple sources.<p>Plus, there are other ethical questions. Did you want to support the military government of Fiji? Or Nestlé&#x27;s success in limiting the rights of Michigan citizens to bring legal action to &quot;protect the state&#x27;s natural resources from pollution, impairment or destruction&quot;? Because those are some of the side-effects of choosing bottled water.<p>In addition, of course, to all the packaging waste and transport costs.
