Summary

PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.

Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.

PFAS
Above limitPFOA, PFOS, HFPO-DA (GenX), the PFAS Hazard Index above the federal limit in EPA's 2023–2025 testing (PFOA 26 ppt vs a limit of 4 ppt, PFOS 5.85 ppt vs a limit of 4 ppt, HFPO-DA (GenX) 33.5 ppt vs a limit of 10 ppt, where ppt = parts per trillion).
Lead
Below action level0 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period ending Dec 2025. Your home's pipes can make yours higher.
Violations
Resolved1 health-based violation since 2016, most recently Jul 2019.
What you can do
  • Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
  • To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
  • Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.
  • Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
  • Read Robeson County Water System's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (910) 671-3485. EPA: how to find it.

PFAS (“forever chemicals”)

EPA UCMR 5: 12 entry points tested Feb 2023 to Jul 2023. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.

For context: the PFOA average is higher than at 99% of the North Carolina systems EPA tested, the PFOS average is higher than at 81% of the North Carolina systems EPA tested and the HFPO-DA (GenX) average is higher than at 99% of the North Carolina systems EPA tested.

29 PFAS tested, 10 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.

Lithium

Detected in 1 of 24 samples. Highest result 12 ppb. EPA's non-enforceable screening level is 10 ppb. Below screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.

Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.

Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.

Questions

Is Robeson County Water System water safe to drink?

Robeson County Water System had 1 health-based violation since 2016, all since resolved. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.

Does Robeson County Water System water have PFAS?

Yes. EPA's 2023–2025 testing of Robeson County Water System found 10 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS and HFPO-DA (GenX): PFOA 26 ppt, PFOS 5.85 ppt, HFPO-DA (GenX) 33.5 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).

What is the lead level in Robeson County Water System water?

The most recent 90th-percentile lead result for Robeson County Water System is 0 ppb, for the period ending Dec 2025. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
