NEW TEST RESULTS COMING NOV 2026
Drinking water can contain a variety of unwanted contaminants, including heavy metals, chemicals, disinfectants, and sediment. These substances can affect water quality, taste, odor, and overall safety. Sentry H2O incorporates specialized filtration technologies designed to address these concerns while preserving naturally occurring beneficial minerals:
By integrating adsorption, oxidation-reduction, electrochemical interactions, mineral filtration, and pH optimization, Sentry H2O delivers a comprehensive, multi-stage filtration approach designed to improve water quality while maintaining naturally occurring beneficial minerals.

NEW TEST RESULTS COMING NOV 2026
PFAS are synthetic chemicals commonly found in nonstick cookware, waterproof materials, and industrial products. Known as forever chemicals, they resist natural breakdown and can accumulate in water supplies and the environment. Exposure to certain PFAS has been linked to health concerns, including immune system disruption, liver damage, and increased cancer risks.
Sentry H2O utilizes two advanced filtration technologies to address water contaminants:

Sentry Wellness System
Summit Environmental Technologies, Inc. tested East Palestine water samples for vinyl chloride in May 2023.
The testing included untreated lab controls, treated samples used to verify vinyl chloride recovery, and a treated non-spiked water sample.
| 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.
