Independent Lab Test Results

Toxins & Minerals Water Report

Sentry Wellness System & Whole House System

Tap Score's SimpleLab tested for contaminants and minerals in three samples of water from Tempe, AZ in 2025. Sample 1 is untreated water. Sample 2 was treated with the under-sink Sentry Wellness System for 6 months. Sample 3 was treated with the Sentry Whole House System for 12 months.

This testing shows significant decreases in harmful toxins like Arsenic, Fluoride, Lead, Uranium & more, as well as an increase in healthy minerals like pH and Alkalinity.

PFAS Water Report

Sentry Wellness System & Whole House System

Tap Score's SimpleLab tested for PFAS (Per- and polyfluoroalkyl substances) in three samples of water from Tempe, AZ in March 2024. Sample 1 is untreated water. Sample 2 was treated with the Sentry Wellness System. Sample 3 was treated with the Sentry Whole House System.

This testing shows significant decreases in PFAS in the water samples treated by the Sentry Wellness System and Sentry Whole House System.

Vinyl Chloride Water Report

Sentry Wellness System

Summit Environmental Technologies, Inc. tested three samples of water from East Palestine, Ohio in May 2023. Sample 1 is a lab-controlled sample spiked with vinyl chloride not treated with the Sentry Wellness System. Samples 2 and 3 were treated with the Sentry Wellness System and then spiked with vinyl chloride to show the lab’s ability to recover vinyl chloride. Sample 4 was non-spiked water treated with the Sentry Wellness System.

This testing shows that no amounts of vinyl chloride were detected in the non-spiked East Palestine water sample using the Sentry Wellness System.

WATER SAMPLE TESTED FOR VINYL CHLORIDE AMOUNT OF VINYL CHLORIDE FOUND IN SAMPLE MAXIMUM ACCEPTABLE CONTAMINANT LEVEL PERCENTAGE OF ACCEPTABLE CONTAMINANT LEVEL REACHED
Sample 1 - Untreated, Spiked Lab Control 4.04 μg/L 5.0 μg/L 80.8%
Sample 2 - Treated then Spiked 5.28 μg/L 5.0 μg/L 106%
Sample 3 - Treated then Spiked 5.22 μg/L 5.0 μg/L 104%
Sample 4 - Treated, NOT Spiked ND (Not Detected) 5.0 μg/L 0%

Unit of Measurement: μg/L = Micrograms per Liter

Arsenic & Uranium Water Report

Sentry Whole House System for Well Water

Aquatek Labs tested two customer-supplied well water samples from Newtown, CT in February and March 2024. Sample 1, taken in February, is the well water prior to treatment. Sample 2, taken in March, is the well water after being treated by the Sentry Well Whole House System.

This testing shows that before treatment, Arsenic and Uranium levels did not meet established EPA and/or CT potability standards and was not safe for drinking. After treating with the Well Whole House System, these contaminants were drastically reduced and the water is now safe for drinking.

CONTAMINANTS MAXIMUM ACCEPTABLE CONTAMINANT LEVEL UNTREATED WELL WATER WELL WATER TREATED WITH SENTRY WELL WHOLE HOUSE SYSTEM
Arsenic 10 15.5 1.72
Uranium 30 92.7 3.45

Unit of Measurement: μg/L = Micrograms per Liter
