im in Huntington Beach, CA. I used 3 Gallons of purified water and 2 Gallons of tap water. The water here doesn't seem to smell, it does taste like tap water but nothing too terrible. I think you will be okay; but I am going to definitely use all purified water on my next batch. Maybe I'll do a brew of 5 gal purified and a 5 gal of SoCal tap water to see the differences.
