ELI5. After a hurricane if everyone had a “life straw” could they drink the ground water?
In: Biology
There are reverse osmosis filters that can remove chemicals. The problem is that they are expensive and require power. Lots of people have them setup on faucets or whole house, but that doesn’t help when power is out.
I couldn’t find any that were portable and meant for disasters. My guess is that cheaper to store water at home or distribute water. Would also need to distribute solar panels and batteries. It might make sense if water is out for long time and have to use stream.
