Buys water from City of Leander, City of Florence, City of Round Rock. Treated water bought from another system can carry that system's contaminants.
Summary
No federal limits exceeded in EPA data.
- PFAS
- Detected, below limit7 of 29 PFAS found at least once. All averages below the federal limits.
- Lithium
- Above screening levelHighest result 17.4 ppb. EPA uses 10 ppb to decide what to study further. It is not a health limit, and there is no federal limit for lithium. About 1 in 4 systems tested were above it.
- Lead
- Below action level4.81 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 2024 – 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 Apr 2026.

- Want to reduce what was found? Filters for these results.
- Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
- Read City of Georgetown'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) 930-3651. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 6 entry points tested Jun 2023 to Feb 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 One sample above limit Limit 4 ppt | 1.22 ppt 31% of the limit |
| PFOS One sample above limit Limit 4 ppt | 3.63 ppt 91% of the limit |
| PFHxS Detected, below limit Limit 10 ppt | 3 ppt 30% of 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) Detected, below limit Limit 1 | 0.3 |
| PFBS Detected, below limit Guideline 2,000 ppt | 8.97 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 16.9 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 4.22 ppt |
| PFPeA Detected, no limit | 8.85 ppt |
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
Detected in 10 of 22 samples. Highest result 17.4 ppb. EPA's non-enforceable screening level is 10 ppb. Above 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: 4.81 ppb lead (Jan 2024 – now (in progress)). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2024 – now (in progress) | 4.81 ppb |
| Jan 2023 – Jun 2023 | 2.23 ppb |
| Jul 2022 – Dec 2022 | 2.6 ppb |
Earlier results (9)
| Jan 2018 – Dec 2020 | 1.8 ppb |
| Jul 2017 – Dec 2017 | 3.1 ppb |
| Jan 2017 – Jun 2017 | 3.9 ppb |
| Jan 2014 – Dec 2016 | 3.91 ppb |
| Jan 2011 – Dec 2013 | 2.7 ppb |
| Jan 2008 – Dec 2010 | 2.63 ppb |
| Jan 2005 – Dec 2007 | 5.3 ppb |
| Jan 1999 – Dec 2001 | 4.1 ppb |
| Jan 1996 – Dec 1998 | 4.5 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 |
|---|---|
| Apr 2026 | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 0.081 mg/l (limit 0.080 mg/L) 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 | 22 ppb | 300 ppb |
| Vanadium | 3 ppb | 21 ppb |
| Chlorate | 1,400 ppb | 210 ppb |
| Strontium | 0.98 ppm | 1.5 ppm |
| Chromium-6 | 0.28 ppb | – |
| Molybdenum | 2.2 ppb | 40 ppb |

Questions
Is City of Georgetown water safe to drink?
City of Georgetown had 1 health-based violation since 2016, all since resolved. EPA testing found no PFAS above the federal limits. 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 City of Georgetown water have PFAS?
Yes. EPA's 2023–2025 testing of City of Georgetown found 7 PFAS at least once. None of the averages were above the federal limits.
What is the lead level in City of Georgetown water?
The most recent 90th-percentile lead result for City of Georgetown is 4.81 ppb, for the monitoring period that began Jan 2024 (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.
