Check with state health dept, they should be able to give you name of a lab that you can take or send a sample of your water to, to have it tested. People have lived off of well water for long before city water was ever thought of. In fact most smaller citys draw thier water from wells, some get thier water from rivers and such, AND if you check your bottled water it was bottled in the city right off of thier water supply, it was filtered a time or two but still its just filtered city water that came out of a well or even worse out of a river.
