Based on EPA UCMR5 monitoring data, EPA SDWIS federal violations records, and EWG Tap Water Database published findings.
This system serves a historically industrial area. EWG and EPA records identify contaminants consistent with legacy manufacturing, chemical processing, or related industrial activity in the watershed. HAVEN presents published EPA and EWG findings; independent testing is the only way to assess your specific tap's composition with certainty.
Water source: Surface water (Schuylkill River)
Water utility: City of Reading Water
Detected at approximately 7.3 ppt per EPA monitoring data — above the EPA's 4 ppt maximum contaminant level (effective 2026). Reverse osmosis or AquaTru filtration removes 99%+ of PFAS compounds.
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.
EPA SDWIS records show 0 health-based violation(s) and 1 lead action-level violation(s) in the past 5 years at this utility. Violations reflect the legal threshold; actual health risk at sub-violation levels is addressed by EWG health guidelines used in HAVEN's scoring.
Reverse osmosis filtration is strongly recommended. AquaTru Carafe ($149) or APEC ROES-50 under-sink RO ($250) remove essentially all documented contaminants in this system. Standard pitcher filters are NOT sufficient for this risk level.
