We lived on the Mn Iron Range for a while and camped, fished and hunted along the Gunflint trail for many years .
The water along the trail was fine for drinking , cooking , and cleaning . IMHO
If you want to filter your water go for it but we never saw any need
The water around the Mesabi Range does have a lot of iron in it
