PFAS Detected Below EPA Limits
PFAS compounds have been detected in water systems serving ZIP 94708, but all levels are currently below EPA MCLs. PFAS accumulate in the body over time, so even low levels warrant attention, especially for pregnant women and young children.
Health Effects of PFAS Exposure
What You Should Do
Test Your Water for PFAS
EPA data shows system-wide results. A home water test measures what comes out of your faucet.

Water systems serving ZIP code 94708 have 2 PFAS detections across 1 compounds. All detected levels are currently below EPA MCLs, but PFAS accumulate in the body over time.
| Compound | Max Detected | MCL | Exceeds? |
|---|---|---|---|
| PFBA | 0.0052 µg/L | null µg/L | No |
What Are PFAS?
PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals used since the 1940s in nonstick cookware, waterproof clothing, food packaging, and firefighting foam. Known as "forever chemicals" because they don't break down in the environment, PFAS accumulate in drinking water, soil, and human blood.
In 2024, the EPA established the first-ever national drinking water standards for six PFAS compounds:
| Compound | EPA MCL (µg/L) |
|---|---|
| PFOA | 0.004 |
| PFOS | 0.004 |
| PFHxS | 0.010 |
| PFNA | 0.010 |
| HFPO-DA (GenX) | 0.010 |
| Mixture of 2+ | Hazard Index of 1 |
Health Effects
PFAS exposure is linked to:
- Certain cancers (kidney, testicular)
- Thyroid disease
- Immune system effects
- Reproductive and developmental issues
- Elevated cholesterol
Recommended Actions
- Consider a PFAS-certified filter — especially if you have children or are pregnant
- Monitor utility reports — PFAS levels can change as EPA testing expands
- Reduce other PFAS exposure — avoid nonstick cookware, stain-resistant fabrics, and microwave popcorn bags
About This Data
PFAS data comes from EPA's Enforcement and Compliance History Online (ECHO) system and the Fifth Unregulated Contaminant Monitoring Rule (UCMR5). Testing is ongoing — new data is added as utilities complete required monitoring. ZipCheckup updates PFAS data monthly.
Frequently Asked Questions
How accurate is this PFAS check?
This report is based on EPA UCMR5 monitoring data and ECHO enforcement records for water systems serving your ZIP code. It reflects system-level testing, not individual tap results. For your specific home, consider a certified lab test.
What should I do if PFAS is detected in my water?
Install an NSF/ANSI 58 (reverse osmosis) or NSF P473 certified water filter. These remove 90-99% of PFAS compounds. Contact your water utility to ask about their PFAS compliance plan and timeline.
What are safe PFAS levels in drinking water?
The EPA set the first federal limits in 2024: 4 ppt for PFOA and PFOS, and 10 ppt for PFHxS, PFNA, and GenX. Any detection above these levels requires utility action by 2029.
Can boiling water remove PFAS?
No. Boiling water does not remove PFAS and can actually concentrate them. Only certified filtration systems (reverse osmosis, activated carbon block, or ion exchange) effectively reduce PFAS levels.
How often is PFAS data updated?
ZipCheckup updates PFAS data monthly from EPA sources. The UCMR5 monitoring program runs through 2025, so new results are added as utilities complete required testing.
