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 above the federal limit in EPA's 2023–2025 testing (PFOA 5.1 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level6.4 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 2023. Your home's pipes can make yours higher.
- Violations
- Resolved2 health-based violations since 2016, most recently Aug 2025. 2 required an urgent public notice within 24 hours (the kind behind boil-water notices), most recently Aug 2025. What to do if you get a notice.
- 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 Savannah-I & D 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 (912) 964-0698. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Apr 2024 to Jan 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 | 5.1 ppt 1.28× the limit |
| PFOS One sample above limit Limit 4 ppt | 3.6 ppt 90% of 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 | 0.0019 |
| PFBS Detected, below limit Guideline 2,000 ppt | 3.85 ppt |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
| PFPeA Detected, no limit | 0.8 ppt |
For context: the PFOA average is higher than at 92% of the Georgia systems EPA tested.
29 PFAS tested, 4 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: 6.4 ppb lead (Jan 2021 – Dec 2023). Below action level
Highest since 2016: 9.6 ppb (Dec 2020).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2021 – Dec 2023 | 6.4 ppb |
| Jan 2018 – Dec 2020 | 9.6 ppb |
| Jan 2015 – Dec 2017 | 2.8 ppb |
Earlier results (9)
| Jan 2012 – Dec 2014 | 2.5 ppb |
| Jan 2011 – Dec 2013 | 2.7 ppb |
| Jan 2008 – Dec 2010 | 3.3 ppb |
| Jan 2005 – Dec 2007 | 3.2 ppb |
| Jan 2004 – Dec 2004 | 4.7 ppb |
| Jan 2003 – Dec 2003 | 4.3 ppb |
| Jan 2002 – Dec 2002 | 7.1 ppb |
| Jan 2001 – Jun 2001 | 13 ppb |
| Jul 2000 – Dec 2000 | 9.58 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 |
|---|---|
| May 2025 – Aug 2025 2 times | The water was cloudier than allowed at least once. Cloudiness can shield germs from disinfection. Urgent public notice required What that means EPA record: Interim Enhanced Surface Water Treatment Rule · Single Turbidity Exceed (Enhanced SWTR) · measured 1.99 ntu (limit ) Archived |
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 | 11 ppb | 300 ppb |
| Chromium-6 | 0.11 ppb | – |
| Strontium | 0.05 ppm | 1.5 ppm |
| 1,4-Dioxane | 0.36 ppb | 0.35 ppb |
| Vanadium | 0.7 ppb | 21 ppb |

Questions
Is Savannah-I & D Water System water safe to drink?
Savannah-I & D Water System had 2 health-based violations 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 Savannah-I & D Water System water have PFAS?
Yes. EPA's 2023–2025 testing of Savannah-I & D Water System found 4 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA: PFOA 5.1 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in Savannah-I & D Water System water?
The most recent 90th-percentile lead result for Savannah-I & D Water System is 6.4 ppb, for the period ending Dec 2023. 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.
