About Tap Water in Patuxent River, MD

The drinking water in Patuxent River, MD generally meets all federal health standards, earning a solid B grade with a composite safety score of 80/100 across 1 ZIP code. While the primary water utility, Patuxent Naval Air Station (navfac-wash), maintains adequate compliance with EPA regulations, there have been minor or administrative violations on record. Overall, residents receive safe tap water that is actively monitored by Maryland Department of the Environment.

A major factor in Patuxent River'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 ground water, the city utilizes advanced filtration to maintain this standard.

Fortunately, the modeled risk for widespread lead exposure in Patuxent River'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.
