Image proves that only water testing can detect contaminants in water.
Exhibit 1: This is actual tap water from a trusted municipal water system. It looks clear, smells clean, & tastes fine. But it’s not.

Exhibit 2: We extracted microscopic contaminants from the actual tap water that the average person drinks in just two-years and mixed them into the water you see above.

This photo clearly shows the accumulation of those contaminants.

Amazingly, these are just the substances you are exposed to from drinking water... 90% of contaminant exposure comes from showering, cooking, washed dishes & glasses, laundry, etc.
