What the labs found

In the Spout water samples tested, independent labs found these not detected.

"Not detected" means the analyte was below the laboratory's reporting limit in that tested sample. Reporting limits and methods are shown on each report.

Contaminant	Result	Reporting limit	Method / Lab
PFAS (PFOA, PFOS, GenX)	Not detected	~0.002 µg/L	EPA 533 + 20-analyte panel · EMSL & Microbac
Microplastics	Not detected	7 polymer types, all size fractions	PLM / Raman spectrometry · EMSL
Lead & arsenic	Not detected	Pb 0.0004, As 0.001 mg/L	EPA 200.8 · 30+ metal panel
BPA (Bisphenol A)	Not detected	0.02 µg/L	LC/MS/MS · Eurofins
Pharmaceuticals & hormones	Not detected	~40 compounds	LC/MS/MS · Eurofins
VOCs	Not detected	~60 analytes	EPA 524.2
Pesticides & glyphosate	Not detected	180+ analytes	EPA 538 / EPA 547
Dioxins & furans	Not detected	18 congeners	EPA 1613 · Cape Fear
E. coli & total coliform	Not detected	Presence / absence	SM 9223B

The water itself

Clean, soft, lightly alkaline.

From the comprehensive panel (report OS13G8, sample 477, Mar 2025). Spout water starts as vapor, so it is naturally low-mineral; we add back calcium, magnesium, and potassium for taste.
