Potable Water
Potable Water Testing
Potable water is one of the most critical utilities in any food, beverage, pharmaceutical, or packaging facility. This water can contact product, equipment, ice, and employees’ hands throughout your facility. Verifying its microbiological quality is essential to controlling risk, supporting compliance, and protecting product safety.
Why Test?
Bacteria occur naturally in water. Most are harmless, but some can cause illness, infections, or serious health risks. Because it is not practical to test for every pathogen, laboratories test for key indicator bacteria that signal potential contamination.

With Routine Testing You Can
- Protect product quality and reduce risk
- Detect potential contamination early
- Meet FDA, EPA, and food safety program requirements (SQF, BRCGS, FSSC 22000)
- Verify water quality at the point of use, not just the source
- Receive clear, audit-ready results with defined acceptance limits
