Mesa Water Report

(Sentry Wellness System)

Aquatic Consulting & Testing, Inc. tested a sample of Mesa, AZ water in 2022 after it was treated with the Sentry Wellness System. This testing shows a significant decrease in harmful toxins, including arsenic, chromium, and fluoride, as well as an increase in good minerals, including calcium, magnesium, and pH.

The chart below shows the amount of each contaminant and mineral present in Mesa, AZ water without treatment and the amount of each found after treatment with the Sentry Wellness System. The chart also shows the increase in the amount of each contaminant found in untreated Mesa, AZ water between 2020 and 2021.

CONTAMINANTS & MINERALS 2020 MESA WATER WITHOUT TREATMENT* 2021 MESA WATER REPORT WITHOUT TREATMENT** MESA WATER TREATED WITH SENTRY WELLNESS SYSTEM
Arsenic 4.5 ppb 6 ppb <0.5 ppb
Chromium 9 ppb 12 ppb <0.1 ppb
Fluoride 0.53 ppm 0.615 ppm <0.5 ppm
Calcium 67 ppm 64 ppm 100 ppm
Magnesium 25.5 ppm 25.5 ppm 198 ppm
pH 7.65 SU 7.635 SU 8.5 SU

Units of Measurement: ppb = parts per billion, ppm = parts per million, SU = Standard Units

*These are averages of the sample ranges listed in the City of Mesa Water Resources 2020 Water Quality Consumer Confidence Report. For example, the range listed for arsenic is 1.2-7.8 ppb, so the average amount of arsenic found in Mesa, AZ water in 2020 was 4.5 ppb.

**These are averages of the sample ranges listed in the Mesa Water Report by Aquatic Consulting & Testing, Inc.. For example, the range listed for arsenic is 1.2-10.8 ppb, so the average amount of arsenic found in Mesa, AZ water in 2021 was 6 ppb.

Tempe Water Report

(Sentry Wellness System)

Aquatic Consulting & Testing, Inc. tested a sample of Tempe, AZ water in 2023 after it was treated with the Sentry Wellness System. This testing shows a significant decrease in harmful toxins, including arsenic, chromium, and fluoride, as well as an increase in good minerals, including calcium, magnesium, and pH.

The chart below shows the amount of each contaminant and mineral present in Tempe, AZ water without treatment and the amount of each found after treatment with the Sentry Wellness System. The chart also shows the increase in the amount of several contaminants found in untreated Tempe, AZ water between 2020 and 2021.

CONTAMINANTS & MINERALS 2020 TEMPE WATER WITHOUT TREATMENT* 2021 TEMPE WATER REPORT WITHOUT TREATMENT* TEMPE WATER TREATED WITH SENTRY WELLNESS SYSTEM
Arsenic 2.8 ppb 2.56 ppb <0.5 ppb
Cadmium N/A N/A <0.001 ppm
Chromium 4.6 ppb 4.5 ppb <0.1 ppb
Copper 0.15 ppm 0.2 ppm <0.005 ppm
Fluoride 0.51 ppm 0.58 ppm <0.5 ppm
Iron N/A N/A 0.17 ppm
Lead 2.7 ppb 5 ppb <0.1 ppb
Nitrate 3.55 ppm 3.5 ppm 1 ppm
Hardness 212 ppm 240 ppm 191 ppm
pH 7.65 SU 7.635 SU 9.0 SU

Units of Measurement: ppb = parts per billion, ppm = parts per million, SU = Standard Units

*These are averages of the sample ranges listed in the City of Tempe 2020 and 2021 Consumer Confidence Reports. For example, the range listed for arsenic in 2020 is 0-5.6 ppb, so the average amount of arsenic found in Tempe, AZ water in 2020 was 2.8 ppb.

PFAS Water Report

(Sentry Wellness System & Whole House System)

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.

PFAS UNTREATED WATER TREATED WITH SENTRY WELLNESS SYSTEM TREATED WITH SENTRY WHOLE HOUSE SYSTEM
Perfluorobutanesulfonic acid 0.49004031* 0.00033900 (99.93% reduction) 0.00054230 (99.89% reduction)

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

*These untreated samples tested above the highest concentration of contaminant permitted by the EPA, exceeding what is deemed safe to consume before adverse health effects can occur.

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
