Based on EPA UCMR5 monitoring data, EPA SDWIS federal violations records, and EWG Tap Water Database published findings.
EPA and EWG records place this utility in a low-contamination category. Source water from protected high-elevation or low-industrial watersheds tends to require less chemical treatment, which also reduces disinfection byproduct formation. HAVEN recommends confirming with your utility's annual Consumer Confidence Report.
Water source: Surface water (Lake Monroe)
Water utility: City of Bloomington Utilities
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.
