Buys water from Bluffdale Water System, Jordan Valley Water Conservancy District. Treated water bought from another system can carry that system's contaminants.

Summary

No federal limits exceeded in EPA data.

PFAS
Detected, below limit2 of 29 PFAS found at least once. All averages below the federal limits.
Lithium
Above screening levelHighest result 33 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 level3.8 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
Resolved1 health-based violation since 2016, most recently Jul 2017.
What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 4 entry points tested Mar 2023 to Jan 2024. "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, 2 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 7 of 12 samples. Highest result 33 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

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.

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.
