Has anyone ever gotten a full water report for Minneapolis tap water? Overall I'm pretty happy with brewing with straight tap water (after I use campden tablets to remove the chloramine), but I'm wondering what its mineral content actually is.

I've seen the reports available on the Mpls water site, but they don't provide much info relevant for brewing.
