PFAS Safe Level Checker (EPA, RIVM & WHO)
Enter your PFAS level (ng/L or ppt) to compare it against international safety guidelines.
Why use this PFAS Water Safety Checker?
Understanding PFAS levels in drinking water can be confusing. Lab reports often contain technical units like ng/L or ppt, and different countries use different safety guidelines. This tool simplifies everything into a clear answer: Is your water safe or not?
By comparing your PFAS level against trusted international standards such as EPA (United States), RIVM (Netherlands), and WHO guidance, you get a fast and reliable interpretation without needing scientific expertise.
- ✔ Instant PFAS safety check
- ✔ Based on real international guidelines
- ✔ Easy to understand (no technical jargon)
- ✔ Helps you decide if action is needed
Frequently Asked Questions (FAQ)
What is PFAS and why is it dangerous?
PFAS (per- and polyfluoroalkyl substances) are a group of man-made chemicals used in industrial and consumer products. They are often called “forever chemicals” because they do not break down easily in the environment or the human body. Long-term exposure has been linked to immune system effects, hormonal disruption, and other health concerns.
What is considered a safe PFAS level?
Safety levels vary slightly by authority, but they are all very low:
- EPA (US): around 4 ng/L for key PFAS (PFOA & PFOS)
- RIVM (Netherlands): around 4.4 ng/L combined PFAS guidance
- WHO: recommends minimizing PFAS exposure as much as possible
Even small amounts can be relevant because PFAS accumulate over time.
Is PFAS in tap water common?
Yes. PFAS contamination has been detected in water sources around the world, including Europe and the Netherlands. It is often linked to industrial activity, firefighting foam, and waste sites.
How can I remove PFAS from drinking water?
The most effective methods include:
- Reverse osmosis (RO) systems
- Activated carbon filtration
These technologies are widely used to significantly reduce PFAS levels in household drinking water.
Should I be worried about my PFAS level?
If your PFAS level is above recommended guidelines, it is wise to take it seriously—especially for long-term exposure. This tool helps you quickly assess your situation and decide whether further action or filtration is needed.
How accurate is this PFAS checker?
This tool provides a simplified interpretation based on widely accepted public health guidelines. While it is useful for quick insights, it should not replace professional water testing or official advice from local authorities.
Take Action if Needed
If your PFAS levels are above recommended limits, consider taking steps to reduce exposure. Installing a certified filtration system or consulting a water specialist can help protect your household.
