Analysis

What to know about Vienna's water

Vienna ranks #329 out of 511 cities in Ohio for water quality, placing it below average in the state.

The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.

Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.

Hexavalent chromium (chromium-6) was detected at 0.03 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

Where Vienna's water comes from

Purchased Surface Water

Vienna's drinking water comes primarily from surface water sources such as rivers, lakes, or reservoirs.

Surface water systems require multi-stage treatment including coagulation, sedimentation, filtration, and disinfection to meet EPA Safe Drinking Water Act standards.

These sources can be impacted by seasonal changes, stormwater runoff, upstream agriculture, and industrial discharge.

The system is operated by private ownership and serves approximately 30,738 people through 7 water systems.

Is Vienna, OH tap water safe to drink?

Vienna's water quality earned a grade of B (77.2/100). Some concerns have been identified. Consider a water filter for an extra layer of protection. The city ranks #329 out of 511 cities tested in Ohio.

What contaminants are in Vienna's water?

Lead was measured at 0.0 ppb (90th percentile). 6 PFAS compounds were detected. 55 violations are on record.

How is Vienna's water quality grade calculated?

The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.

Do I need a water filter in Vienna?

PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.

Where does Vienna's water come from?

Vienna's water is sourced from Purchased surface water. The city has 7 water systems serving approximately 30,738 residents.

What health violations has Vienna's water system had?

Vienna has 9 health-based violations on record. The most recent violation was recorded in January 2019. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 14 violations remain unresolved.

Why does Vienna have so many PFAS compounds in its water?

6 different PFAS "forever chemical" compounds were detected in Vienna's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.

How does Vienna's water compare to other cities?

Vienna ranks #329 out of 511 cities in Ohio (better than 36% of state cities) and #9061 out of 15744 cities nationally (43th percentile). The grade of B reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
