We collected water samples from four sources:
1. Tap Water
2. Berkey Filtered Tap Water (ceramic, charcoal and flouride filters)
3. Zero Water
4. Zephyrhills bottled spring water
We sent the four samples to KAR Labs (www.karlabs.com) for a test that will check 38 different things, including metals, bacteria, chrloring, pH, and others.
We will post our results and evaluation when we get them from KAR.
