First call your water authority/company to acquire those numbers you need. They have them, but are not required to publish them, so they often don't. You're posing as a consumer interested in the quality of your drinking water, particularly those minerals and parameters.
If you end up sending to Ward labs get the cheaper $21 W-6 "household water test" and send in your own bottle, don't get the kit. Word of caution, any sample is only a snapshot. Depending on your water company's water resources these numbers may change any time with the seasons or for other reasons.
I lived in a city where water was pumped out of a river 15 miles southeast when the local reservoir was running "low." This was mostly during the summer. The difference in quality was enormous. The water also turned green during those periods, but I couldn't quite process film in it, yet.
