Based on EPA UCMR5 monitoring data, EPA SDWIS federal violations records, and EWG Tap Water Database published findings.
Federal monitoring data places this system in a moderate contaminant detection category. Several compounds are detected above EWG health guidelines — the more conservative thresholds that reflect long-term exposure risk rather than acute toxicity. A quality point-of-use filter addresses most of the identified concerns.
Water source: Groundwater (carbonate aquifer)
Water utility: State College Water Authority
Detected at approximately 3.0 ppt per available EPA data — below the new EPA MCL of 4 ppt but above levels many health researchers consider optimal for lifetime daily consumption. Reverse osmosis filtration is recommended.
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.
Reverse osmosis filtration is recommended — AquaTru Carafe ($149) or APEC ROES-50 under-sink RO ($250). RO removes 99%+ PFAS, lead, nitrates, arsenic, chromium, and disinfection byproducts in a single system.
