Bottle water vs tap test with TDS HD

Testing water with TDS tester determined that the following waters are not as safe to drink as we think. These are the bottle waters we buy over tap water because of the notion that bottle water is better and more pure. The results I did with my TDS tester purchased no more than three weeks ago are as follows. Tap water tested around 53 (ideal drinking water) Great Value spring water 130 (Hard Water) SpringTime 154 (Hard Water) 365 Spring Water 195( Hard Water). The verdict is tap water wins. I do however live in a new complex less than 6 months old so the pipes are new. Do your own testing and maybe let me know what type of tests you have done.
