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 above the federal limit in EPA's 2023–2025 testing (PFOA 5.77 ppt vs a limit of 4 ppt, PFOS 6.07 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level6.9 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 2024. Your home's pipes can make yours higher.
- Violations
- Resolved1 health-based violation since 2016, most recently Jul 2017.
- 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 Gcwsd Waccamaw Neck 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 (843) 237-9727. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Oct 2024 to Aug 2025. "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 Above limit Limit 4 ppt | 5.77 ppt 1.44× the limit |
| PFOS Above limit Limit 4 ppt | 6.07 ppt 1.52× the limit |
| PFHxS Not detected Limit 10 ppt | – |
| 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) Detected, below limit Limit 1 | 0.0015 |
| PFBS Detected, below limit Guideline 2,000 ppt | 3.08 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 1.7 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 4.05 ppt |
| PFPeA Detected, no limit | 5.5 ppt |
| PFHpA Detected, no limit | 2 ppt |
For context: the PFOA average is higher than at 91% of the South Carolina systems EPA tested and the PFOS average is higher than at 76% of the South 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 4 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 6.9 ppb lead (Jan 2022 – Dec 2024). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 6.9 ppb |
| Jan 2019 – Dec 2021 | 3.9 ppb |
| Jan 2016 – Dec 2018 | 2.6 ppb |

| Jan 2003 – Jun 2003 | 13 ppb |
| Jan 2001 – Jun 2001 | 47 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 |
|---|---|
| Jul 2017 | The running annual average for Total Haloacetic Acids (HAA5) was above the legal limit. EPA record: Total Haloacetic Acids (HAA5) · Maximum Contaminant Level Violation, Average · measured 0.062 mg/l (limit 0.060 mg/L) 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.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 2.55 ppb | 300 ppb |
| Chlorate | 340 ppb | 210 ppb |
| Strontium | 0.057 ppm | 1.5 ppm |
| Chromium-6 | 0.059 ppb | – |
| 1,4-Dioxane | 0.55 ppb | 0.35 ppb |

Gcwsd Waccamaw Neck 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 Gcwsd Waccamaw Neck Water System water have PFAS?
Yes. EPA's 2023–2025 testing of Gcwsd Waccamaw Neck Water System found 7 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 5.77 ppt, PFOS 6.07 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in Gcwsd Waccamaw Neck Water System water?
The most recent 90th-percentile lead result for Gcwsd Waccamaw Neck Water System is 6.9 ppb, for the period ending Dec 2024. The federal action level is 15 ppb, falling to 10 ppb in November 2027.
