Reverse osmosis (drinking water)

The treatment category most often matched to dissolved contaminants like lead, arsenic, nitrate, fluoride, and radiological contaminants detected in this system.

Whole-house carbon filtration

The treatment category most often matched to disinfection byproducts (TTHMs, haloacetic acids), chlorine taste and odor, and organic compounds detected in this system.

Source: U.S. EPA Six-Year Review 4 compliance monitoring data (2012–2019), the most recent nationwide compliance dataset EPA has released, reported at the water-system level. A detection is not a violation. “Avg. vs. limit” compares the average of laboratory detections to the federal MCL or action level; individual faucets can differ — household plumbing affects lead and copper, and a state-certified laboratory test of your own tap is the only way to confirm levels in your home. Treatment categories are general matches, not a certification claim for a specific product and contaminant.

Water Utility: City of Toledo
Population Served: 360,000 residents
Data Sources: EPA SDWIS + EPA UCMR5
Report Year: 2026

Toledo, Ohio drinking water is supplied by City of Toledo. All US public water systems must test drinking water and report results to the EPA under the Safe Drinking Water Act. This report summarizes health-based violations and PFAS detections recorded in federal databases to help you make informed decisions about home water filtration.

EPA Health-Based Violation History

The following contaminants exceeded EPA maximum contaminant levels (MCLs) at this utility since 2010:

Contaminant Violation Years Filter Solution
Interim Enhanced Surface Water Treatment Rule 2023 Water Filters
Surface Water Treatment Rule 2015 Water Filters
Tthm 2014 Water Filters

Source: EPA Safe Drinking Water Information System (SDWIS), updated quarterly. Health-based violations only.

PFAS "Forever Chemical" Detections

PFAS compounds were detected in this water system during EPA's Fifth Unregulated Contaminant Monitoring Rule (UCMR5) testing program (2023-2025). EPA has set maximum contaminant levels of 4 parts per trillion (ppt) for PFOA and PFOS individually.

PFAS Compound Level Detected Solution
PFBA 0.0050 ug/L PFAS Filters

Source: EPA UCMR5 occurrence data. Levels in micrograms per liter (ug/L = parts per billion). 1 ug/L = 1,000 ppt.

Should You Filter Your Toledo Water?

Even utilities with no EPA violations may have contaminants present below legal limits but above health guidelines. The EPA sets maximum contaminant levels based on what is feasible and affordable to treat at scale -- not necessarily what carries zero health risk. Many independent health organizations recommend filtration for households with children, pregnant women, or immunocompromised individuals regardless of utility compliance status.

Frequently Asked Questions

Is Toledo tap water safe to drink?

City of Toledo is required to meet EPA federal drinking water standards. However, meeting legal standards is not the same as being contaminant-free. Trace levels of disinfection byproducts, PFAS compounds, and other regulated contaminants are common in US municipal water systems.

Does Toledo water have PFAS?

PFAS monitoring data for this utility may not yet be published in EPA databases. We recommend a reverse osmosis system for maximum protection regardless of local results.

What water filter works best for Toledo?

A whole-house carbon block filter removes chlorine, chloramines, and many VOCs. For PFAS, arsenic, and nitrates, a reverse osmosis under-sink system provides the highest reduction rates. Take our free 2-minute quiz to find the right system for your home and budget.
