Bronx, NY Tap Water Quality

Tap water quality in Bronx, NY is a significant concern, currently receiving a below-average safety score of 51/100 across 25 ZIP codes. With 0 health-based violations recorded in the past 5 years, systems like YONKERS CITY have struggled to maintain compliance with EPA regulations enforced by New York State Department of Health. Residents are strongly encouraged to utilize certified water filtration systems.

A major factor in Bronx'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. This means that regulated contaminants—such as lead, arsenic, and harmful bacteria—have not exceeded the Maximum Contaminant Levels (MCLs) allowed by federal law. Drawing primarily from surface water, the city utilizes advanced filtration to maintain this standard.

Additionally, lead exposure risk remains a critical issue for certain neighborhoods. EPA data indicates that 25 out of 25 ZIP codes in Bronx 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.
