Frequently Asked Questions for Water in Louisville, Ohio
Is Louisville tap water safe to drink?
Yes. Louisville’s municipal drinking water meets all EPA and Ohio EPA drinking water standards and has no current violations requiring bottled water or boil advisories. As with all public water systems, small amounts of regulated contaminants may be present but remain within legal limits.
Is Louisville water hard?
Yes. Louisville’s water is considered moderately hard to hard, which is common throughout Stark County.
Typical hardness levels generally range from 120–200 mg/L (approximately 7–12 grains per gallon).
Hard water can lead to scale buildup on plumbing and fixtures, reduced soap effectiveness, and increased wear on appliances such as water heaters and dishwashers.
Does Louisville water contain PFAS (“Forever Chemicals”)?
Louisville has participated in EPA PFAS monitoring programs, including UCMR testing. Testing shows extremely low levels of certain PFAS compounds, such as PFPeA (~0.003 ppb), while others were not detected.
PFAS compounds (such as PFOA and PFOS) have been detected in some Ohio water systems, and continued monitoring is required as new EPA PFAS standards take effect. Because PFAS levels can vary by source water and over time, many Louisville residents choose reverse osmosis or advanced carbon filtration for drinking and cooking water as an added precaution.
Does Louisville add fluoride to its water?
Yes. Louisville drinking water contains fluoride to support dental health. Recent testing shows levels around 0.97 ppm, which is below the maximum contaminant level of 4 ppm.
Fluoride levels are typically maintained around 0.7 ppm, which aligns with EPA and public health recommendations for community water fluoridation.
What other contaminants are in Louisville water?
Based on recent Consumer Confidence Reports from the regional supply and routine monitoring, Louisville’s water may contain trace levels of common municipal contaminants.
Inorganic contaminants:
- Combined Radium: 0.067 pCi/L
- Barium: 0.136 ppm
Disinfection byproducts (from chlorination):
- Total Trihalomethanes (TTHMs): typically ~45–60 ppb (EPA limit: 80 ppb)
- Haloacetic Acids (HAA5): typically ~30–45 ppb (EPA limit: 60 ppb)
These byproducts form when chlorine interacts with naturally occurring organic matter. While levels are legally compliant, they are often cited by independent health organizations as a reason homeowners explore additional filtration.
Where does Louisville get its water?
Louisville’s drinking water comes from five groundwater wells located in two different areas. The system supplies an average of approximately 850,000 gallons per day, providing a steady and reliable source of water for the community.
What is the pH level of Louisville water?
While Louisville’s specific pH values are not listed in the report, neutral to slightly alkaline pH ranges common in Northeast Ohio fall around 7.2–7.7, which supports corrosion control, distribution system stability, and acceptable taste.
Should I use a water filter or softener in Louisville?
Yes. Due to hard water and trace disinfection byproducts, many Louisville homeowners benefit from water treatment systems such as:
- Water softeners to reduce scale and protect plumbing and appliances
- Whole-house carbon filtration to reduce chlorine taste and odor
- Reverse osmosis systems for cleaner, better-tasting drinking and cooking water
Does Louisville water have a high total dissolved solids (TDS) level?
Total dissolved solids (TDS) measure the combined minerals and dissolved substances in water. Louisville’s water is generally below the EPA’s secondary (aesthetic) guideline of 500 ppm, which is typical for freshwater municipal supplies.
Even at compliant levels, dissolved minerals contribute to taste differences, mineral residue, and scale buildup, especially in homes with hard water. Many Louisville residents choose filtration or RO systems to reduce TDS for better taste and long-term appliance protection.
Where can I get a local water quality report?
Louisville’s annual Consumer Confidence Report (CCR) is available through the City of Louisville.
The Proof
Why Do Louisville
Homeowners LOVE Us?
We didn’t think our water was that bad until we realized how many small things it was affecting. After installing the system, all of that is gone. It just feels cleaner and easier day to day.
Before, the water felt different depending on where you were in the house. Now everything is consistent in the kitchen, bathrooms, and laundry. It’s a subtle change, but it makes the whole home feel more put together.
The biggest difference for us has been how everything rinses cleaner. There’s no residue left behind and everything just feels fresher. It’s one of those upgrades that quietly improves everything.
