Regulated contaminants · Safe Drinking Water Act
Federally regulated contaminants that were not reported at detectable levels in this system’s most recent monitoring:
We measure what is actually coming out of your taps - hardness, iron, pH, TDS, PFAS, and whatever your own plumbing adds - the things a utility report can never show.
02
See your real results
We walk you through exactly what is there and what it affects: your skin, your pipes, your appliances, and the taste. No scare tactics, no pressure.
03
Get recommendations
Based on your results, we recommend the treatment that fits your water - a softener, reverse osmosis, or whole-home filtration - and nothing you do not need.
