Water Filtration question
I am very new to any sort of prepping but have started to get together a bug-out bag as I’m doing research, right now it’s basically a glorified hiking bag. I’ve looked up a lot of water filtration options and I’ve gone with the Sawyer Mini. I feel there is something I may not be fully understanding and would love if someone could explain. So I’ve noticed that most water filtration systems are good for bacteria but not viruses, heavy metals, or chemicals. I’m wondering how urgent the need for a filtration system that can remove those problems is? Are those issues so abundant that I should be concerned? Or would the filtration system I have to suffice? I live in New England for geographic reference.
