"you can only safely drink from a pond if you have healthy status"

Drinking from emptied gasoline contatiners - "Purify it each time you drink from it or use the water for plants. We kept ours in our tents and barrels for planting but on restarts it would go back to being gasoline for some reason. It might be fixed now, It's been over a year that I have tried doing it , but I would purify just to be safe. Or just carry a few cooking pots filled with water. You can protect your ammo and have plenty of clean water on hand :)"
