1. It’s About the Material, Not the Tank
The FDA does not typically “approve” a specific brand of water tank. Instead, they approve the resins and polymers used to make the tank. For water storage, this is usually high-density polyethylene (HDPE). To be compliant, the plastic must be “virgin” (not recycled) and free from additives that could contaminate the water.
2. Food-Grade vs. FDA Approved
While often used interchangeably, there is a slight distinction:
- FDA Compliant: The raw materials meet the standards set by the Food and Drug Administration.
- Food-Grade: A broader term indicating the finished product is safe for holding food or potable water based on its design and material purity.
3. The Importance of BPA-Free
FDA standards for water storage ensure that the containers do not contain Bisphenol A (BPA). BPA is a chemical often found in polycarbonate plastics that can mimic hormones in the human body. FDA-approved HDPE tanks are naturally BPA-free.
4. What It Doesn’t Cover
It is important to remember that an FDA-approved label does not mean:
- The water will stay fresh forever (you still need to treat it).
- The tank is protected against UV rays (unless it has UV-inhibitors added).
- The tank is “NSF 61” certified (which is a different, more rigorous structural and safety test specifically for potable water).
Conclusion
Choosing an FDA-approved container ensures that your storage vessel won’t poison your water supply with leached chemicals. It is the essential first step in any emergency preparedness or water management plan.
