Largo Water Quality Summary

Largo, FL receives a water quality score of 39/100 (Grade F) based on EPA Safe Drinking Water Information System (SDWIS) compliance data for 1 public water system serving the area.

Largo's water quality score is below the national average, indicating a history of EPA violations or elevated contaminant levels. Residents are encouraged to check their specific water system report and consider additional filtration.

Largo's score of 39 is 25 points below the Florida state average of 64, and below the nationwide average of roughly 78/100 across all U.S. states.

As a large Florida city situated in a Southeast coastal environment, Largo's drinking water is drawn from a regional limestone aquifer that is increasingly stressed by a dense and expanding population. Managing these environmental and geological pressures falls on a centralized water system, which has struggled to maintain acceptable safety and quality standards. For prospective homebuyers and current residents, these poor assessment metrics indicate that tap water quality is a significant concern. Consequently, investigating home filtration systems or alternative water sources may be an important step for daily household use.

Water quality data is sourced from the U.S. EPA SDWIS database and updated quarterly. Learn about our scoring methodology → Read our Florida water quality rankings report →
