Your meat is full of microtoxens then because that wild cattle is drinking water and eating plants that were not perfectly pure to your lofty standards.
It undermines all of the other nonsense you are doing to consume perfectly purified water.
Kek.
Do you eat natural meat and plants or do you farm your own so you can feed them perfectly purified water? /s
Do you filter the aid you breathe too? /s
Sorry, I don't live in fear of myotoxins.
I'm sorry you think you need a perfectly environment to survive.
But also know that sewage can contain many contaminants like petroleum products, heavy metals and corrosive inorganic acids, PFAs, and lot more; chlorine cannot remove all these. Even boiling doesn't make it safe, unfortunately.
Your kitchen tap water and bottled water from the grocery store also contains these things.
You'll need to construct a large sand / charcoal filter or buy some expensive equivalent... but in an emergency no right-minded person would care about such things.
You are amazing.
Wow.
