Warren, NJ Tap Water Quality

Tap water quality in Warren, NJ is a significant concern, currently receiving a below-average safety score of 40/100 across 1 ZIP code. With 0 health-based violations recorded in the past 5 years, systems like NJ AMERICAN WATER - SHORT HILLS have struggled to maintain compliance with EPA regulations enforced by New Jersey Department of Environmental Protection. Residents are strongly encouraged to utilize certified water filtration systems.

A major factor in Warren'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.

Fortunately, the modeled risk for widespread lead exposure in Warren's municipal water is relatively low compared to national averages. However, because lead typically enters drinking water through the corrosion of older, individual home plumbing rather than the main supply lines, residents in homes built before 1986 should still exercise caution by running the tap before use.
