A major factor in Radnor's high rating is its flawless health-based violation record. Over the past 5 years of EPA tracking, local water systems have recorded zero health-based violations.

Additionally, lead exposure risk remains a critical issue for certain neighborhoods. EPA data indicates that 1 out of 1 ZIP codes in Radnor are rated as High or Very High risk for lead. This risk is often driven by aging homes with pre-1986 plumbing containing lead solder or service lines. Families in these areas should test their tap water and consider NSF/ANSI 53 certified filters.
