Data: U.S. EPA · How we read the data · How we check it
Most of Grapevine gets its water from City of Grapevine. Parts of the city are served by a smaller system: Bryan County Rws & Swmd #2 (6,270 people). Your water bill names your system.
Buys water from Tra Tarrant County Water Project, City of Southlake, City of Colleyville. Treated water bought from another system can carry that system's contaminants.

PFAS (“forever chemicals”)
EPA UCMR 5: 2 entry points tested Feb 2023 to Nov 2023. "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 | 3.38 ppt 84% of the limit |
| PFOS One sample above limit Limit 4 ppt | 2.48 ppt 62% 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 | 0.0026 |
| PFBS Detected, below limit Guideline 2,000 ppt | 5.28 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 10 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 13.7 ppt |
| PFPeA Detected, no limit | 12.5 ppt |
| PFHpA Detected, no limit | 2.82 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
Not detected in 8 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 1.7 ppb lead (Jan 2023 – Dec 2025). Below action level
Highest since 2016: 4 ppb (Dec 2016).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2025 | 1.7 ppb |
| Jan 2020 – Dec 2022 | 2 ppb |
| Jan 2017 – Dec 2019 | 3 ppb |
Earlier results (9)
| Jan 2014 – Dec 2016 | 4 ppb |
| Jan 2011 – Dec 2013 | 2.41 ppb |
| Jan 2008 – Dec 2010 | 1.67 ppb |
| Jan 2005 – Dec 2007 | 2.1 ppb |
| Jan 1999 – Dec 2001 | 2.5 ppb |
| Jan 1996 – Dec 1998 | 5.1 ppb |
| Jan 1995 – Dec 1995 | 4.1 ppb |
| Jan 1994 – Dec 1994 | 3 ppb |
| Jan 1993 – Jun 1993 | 10 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
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 | 349 ppb | 300 ppb |
| Molybdenum | 2.53 ppb | 40 ppb |
| Vanadium | 1.74 ppb | 21 ppb |
| Chlorate | 49.4 ppb | 210 ppb |
| Strontium | 0.34 ppm | 1.5 ppm |
| Chromium-6 | 0.14 ppb | – |
