Buys water from Central Utah Water Conservancy District – Utah Valley. Treated water bought from another system can carry that system's contaminants.
Summary
No federal limits exceeded in EPA data.
- PFAS
- Not detectedNone of 29 PFAS found above EPA's reporting limits in 12 samples (2023–2025).
- Lithium
- Above screening levelHighest result 220 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 level1.5 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 Oct 2017.

PFAS (“forever chemicals”)
EPA UCMR 5: 5 entry points tested May 2024 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 Not detected Limit 4 ppt | – |
| PFOS Not detected Limit 4 ppt | – |
| 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) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
29 PFAS tested, 0 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 11 of 12 samples. Highest result 220 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: 1.5 ppb lead (Jan 2022 – Dec 2024). Below action level
Highest since 2016: 4.1 ppb (Dec 2019).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 1.5 ppb |
| Jan 2019 – Dec 2021 | 3.1 ppb |
| Jan 2017 – Dec 2019 | 4.1 ppb |
Earlier results (9)
| Jan 2014 – Dec 2016 | 1.3 ppb |
| Jan 2011 – Dec 2013 | 3.3 ppb |
| Jan 2005 – Dec 2007 | 5 ppb |
| Jan 2003 – Dec 2005 | 5 ppb |
| Jan 2002 – Dec 2002 | 5 ppb |
| Jan 2001 – Dec 2001 | 6 ppb |
| Jan 2000 – Dec 2000 | 5 ppb |
| Jul 1999 – Dec 1999 | 5 ppb |
| Jan 1999 – Jun 1999 | 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 |
|---|---|
| Oct 2017 | An inspection found a significant problem (such as a damaged well or storage tank) that was not fixed on time. EPA record: Groundwater Rule · Failure To Address Deficiency (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 | 0.99 ppb | 300 ppb |
| Strontium | 5.59 ppm | 1.5 ppm |
| Chromium-6 | 0.43 ppb | – |
| Vanadium | 3.29 ppb | 21 ppb |
| Molybdenum | 5.79 ppb | 40 ppb |

Is Eagle Mountain tap water safe to drink?
Most of Eagle Mountain gets its water from Eagle Mountain City Water System. Eagle Mountain City Water System 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.
