City of Pflugerville water quality
Pflugerville, TX · serves 63,464 people (21,462 connections) · Surface water · Local government · EPA ID TX2270014
Data: U.S. EPA · How we read the data · How we check it
Buys water from Manville Water Supply Corporation. 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 limitPFOA, PFOS, PFNA, the PFAS Hazard Index above the federal limit in EPA's 2023–2025 testing (PFOA 6.3 ppt vs a limit of 4 ppt, PFOS 14 ppt vs a limit of 4 ppt, PFNA 24.8 ppt vs a limit of 10 ppt, where ppt = parts per trillion).
- Lead
- Below action level1.1 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
- Resolved14 health-based violations since 2016, most recently Jul 2025.
- 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 City of Pflugerville'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 (512) 990-6101. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 3 entry points tested Mar 2025 to Dec 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 | 6.3 ppt 1.57× the limit |
| PFOS Above limit Limit 4 ppt | 14 ppt 3.49× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 6.85 ppt 69% of the limit |
| PFNA Above limit Limit 10 ppt | 24.8 ppt 2.48× the limit |
| 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) Above limit Limit 1 | 3.14 |
| PFBS Detected, below limit Guideline 2,000 ppt | 9.65 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 8.05 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 8.85 ppt |
| PFPeA Detected, no limit | 12.6 ppt |
| PFHpA Detected, no limit | 4.75 ppt |
| PFUnA Detected, no limit | 2.7 ppt |
For context: the PFOA average is higher than at 99% of the Texas systems EPA tested, the PFOS average is higher than at 99% of the Texas systems EPA tested and the PFNA average is higher than at 99% of the Texas 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 4 of 8 samples. Highest result 13.9 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 and copper
Latest 90th percentile: 1.1 ppb lead (Jan 2023 – Dec 2025). Below action level
Highest since 2016: 3.73 ppb (Dec 2017).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2025 | 1.1 ppb |
| Jul 2022 – Dec 2022 | 1.56 ppb |
| Jan 2022 – Jun 2022 | 1.85 ppb |
Earlier results (9)
| Jan 2019 – Dec 2021 | 2.54 ppb |
| Jan 2018 – Dec 2018 | 2.61 ppb |
| Jul 2017 – Dec 2017 | 3.73 ppb |
| Jan 2017 – Jun 2017 | 2.22 ppb |
| Jan 2014 – Dec 2016 | 2.59 ppb |
| Jan 2011 – Dec 2013 | 2.66 ppb |
| Jan 2008 – Dec 2010 | 3.43 ppb |
| Jan 2005 – Dec 2007 | 4.5 ppb |
| Jan 1999 – Dec 2001 | 5.6 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 – Jul 2025 3 times | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 0.084 mg/l (limit 0.080 mg/L) Resolved |
| Oct 2018 – Dec 2019 11 times | A required step to remove or kill germs (filtration, disinfection or fixing a contaminated well) was not done properly. EPA record: Long Term 2 Enhanced Surface Water Treatment Rule · Treatment Technique (SWTR and GWR) (limit ) 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 | 1.5 ppb | 300 ppb |
| Chromium-6 | 0.13 ppb | – |
| Chlorate | 349 ppb | 210 ppb |
| Vanadium | 1.92 ppb | 21 ppb |
| Molybdenum | 2.53 ppb | 40 ppb |
| Strontium | 0.54 ppm | 1.5 ppm |
