Buys water from Johnston County – East. Treated water bought from another system can carry that system's contaminants.
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 limitPFOS above the federal limit in EPA's 2023–2025 testing (PFOS 10.3 ppt vs a limit of 4 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 Jan 2026 – now, still in progress (results reported so far). Your home's pipes can make yours higher.
- Violations
- Resolved1 health-based violation since 2016, most recently Oct 2024.
- 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 Town of Selma'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 (919) 965-9841. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested May 2023 to Jan 2024. "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.
| Contaminant | Highest average |
|---|---|
| PFOA Not detected Limit 4 ppt | – |
| PFOS Above limit Limit 4 ppt | 10.3 ppt 2.59× the limit |
| PFHxS Rounds to the limit Limit 10 ppt | 12.7 ppt 1.27× the limit |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Rounds to the limit Limit 1 | 1.27 |
| PFBS Detected, below limit Guideline 2,000 ppt | 4.4 ppt |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Detected, below limit Guideline 3,000 ppt | 4.6 ppt |
| PFPeA Detected, no limit | 6 ppt |
| PFHpA Detected, no limit | 1.65 ppt |
| 6:2 FTS Detected, no limit | 8.5 ppt |
Why "rounds to the limit"? the PFHxS average (12.7 ppt) and the Hazard Index (1.27) are slightly above the number on paper, but EPA compares results after rounding to the limit's precision (4.4 ppt rounds to 4), so they meet the limit as EPA applies it. Close enough to the limit to be worth watching.
For context: the PFOS average is higher than at 91% of the North Carolina systems EPA tested.
29 PFAS tested, 7 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
Not detected in 2 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 0 ppb lead (Jan 2026 – now (in progress)). Below action level
Highest since 2016: 2.4 ppb (Dec 2016).

| Jul 2004 – Dec 2004 | 0 ppb |
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.
Violations
| When | What happened |
|---|---|
| Oct 2024 | The system did not publish the required inventory of lead service lines (due October 2024). It says nothing about lead levels in the water. EPA record: Lead and copper rule revisions · LSL Inventory Resolved |
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 Town of Selma water safe to drink?
Town of Selma 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 Town of Selma water have PFAS?
Yes. EPA's 2023–2025 testing of Town of Selma found 7 PFAS at least once. The highest entry-point averages were above the federal limit for PFOS: PFOS 10.3 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in Town of Selma water?
The most recent 90th-percentile lead result for Town of Selma is 0 ppb, for the monitoring period that began Jan 2026 (still in progress). 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.
