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.

Athens, Wisconsin drinking water is supplied by Athens Waterworks. 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:

Should You Filter Your Athens 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 Athens tap water safe to drink?

Athens Waterworks 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 Athens 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 Athens?

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.
