Toledo Water Quality Summary

Toledo, OH receives a water quality score of 82/100 (Grade B) based on EPA Safe Drinking Water Information System (SDWIS) compliance data for 1 public water system serving the area.

Toledo's water quality is above the national average, with strong compliance records and low contaminant levels. Residents generally receive clean, safe tap water that meets EPA standards.

Toledo's score of 82 is 5 points below the Ohio state average of 87, and above the nationwide average of roughly 78/100 across all U.S. states.

As a large city situated along the Great Lakes coastline within the industrial Rust Belt of the Midwest, Toledo relies on a single municipal water system to supply its entire population. For residents and prospective homebuyers, the local tap water generally meets high standards of safety and cleanliness, though there remain minor areas where infrastructure improvements could elevate overall quality. Because the community's water supply is managed through one centralized system, any upgrades or local environmental factors typical of industrial lakefront regions will directly impact the entire urban area.

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