Supplied by Orem City Water System · serves 98,129 people (23,146 connections) · Purchased surface water · EPA ID UTAH25020

Data: U.S. EPA · How we read the data · How we check it

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 16 samples (2023–2025).
Lithium
Above screening levelHighest result 26.9 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 level2.2 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
None health-basedNo health-based violations since 2016.
What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 7 entry points tested Jan 2025 to Oct 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.

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 12 of 16 samples. Highest result 26.9 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: 2.2 ppb lead (Jan 2022 – Dec 2024). Below action level

Highest since 2016: 2.4 ppb (Dec 2021).

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.

Total ever recorded, incl. paperwork

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.

Questions

Is Orem tap water safe to drink?

Most of Orem gets its water from Orem City Water System. Orem City Water System has no health-based violations since 2016. 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 Orem water have PFAS?

EPA tested Orem City Water System for 29 PFAS between Jan 2025 and Oct 2025 and none were detected above the reporting limits (about 2 to 20 ppt depending on the chemical).
