Based on EPA UCMR5 monitoring data, EPA SDWIS federal violations records, and EWG Tap Water Database published findings.
Natural geological factors — including uranium-bearing rock, arsenic-containing sediment, and naturally radioactive radium — contribute to this system's contaminant profile, per EPA SDWIS data. These are common in certain geological formations and are distinct from industrial contamination. RO filtration is the recommended solution.
Water source: Surface water (Provo River)
Water utility: Provo City Water
Not detected in available EPA monitoring data. This is a positive indicator, though PFAS testing coverage is not universal.
The EPA's new maximum contaminant level (MCL) for PFAS is 4 ppt, effective 2026. PFAS compounds have been linked to cancer, thyroid disease, immune disruption, and developmental issues at chronic exposure levels per peer-reviewed research.
The following contaminants have been detected or are associated with elevated risk in this water system, per available EPA and EWG published data:
These detections are drawn from EPA SDWIS federal violations database and EWG Tap Water Database records. EWG health guidelines are stricter than EPA legal limits and reflect long-term exposure risk.
No health-based EPA violations recorded in the past 5 years at this utility. Note: EPA violations reflect legal compliance thresholds, which are less protective than the EWG health guidelines used in HAVEN's scoring model.
A certified pitcher filter (ZeroWater, Clearly Filtered) or under-sink carbon block filter is sufficient for most concerns at this score level. RO filtration provides added peace of mind if PFAS is detected.
