FAQ
Additional Information On Westerville, OH Tap Water
Is Westerville tap water safe to drink?
Yes. Westerville's drinking water meets all Ohio EPA and federal drinking water standards. The Westerville Water Division's most recent water quality report lists no violations, and the system holds a current, unconditioned license to operate.
Is Westerville tap water hard?
Yes. Even after lime softening at the treatment plant, the most recent water quality report shows Westerville's water averaging 119 ppm, or about 7.0 grains per gallon, with a range of 92 to 171 ppm. That falls in the moderately hard to hard range.
Is there PFAS in Westerville tap water?
Westerville's federal UCMR 5 testing, published in the most recent water quality report, detected four PFAS compounds (PFBA, PFBS, PFHxA, and PFPeA) at low parts-per-trillion levels. PFOA and PFOS, the two most closely regulated PFAS, were not listed as detected. Under the federal PFAS rule, utilities must begin compliance monitoring in 2027 and meet the new limits by 2029. Homeowners who want to know what's in their water today can schedule a free water test with Culligan.
Does Westerville tap water have fluoride?
Yes. Westerville adds fluoride during treatment to help protect dental health. The most recent water quality report shows fluoride averaging 1.0 ppm, with a range of 0.76 to 1.09 ppm, well below the EPA maximum contaminant level of 4.0 ppm.
Where does Westerville get its tap water?
Westerville's primary source is surface water from Alum Creek, supplemented by three wells in the Alum Creek Valley Aquifer. Ohio EPA rates both sources as highly susceptible to contamination, and the city maintains a source water protection plan.
How is Westerville water treated?
The Westerville Water Treatment Plant on West Main Street runs 24 hours a day and can treat 7.5 million gallons daily. Treatment includes ferric chloride coagulation, lime and caustic soda softening, pH adjustment, rapid sand filtration, granular activated carbon filtration, chlorine disinfection, phosphate for corrosion control, and fluoride addition.
Do I need a water softener or filter in Westerville?
Because Westerville's water is still moderately hard to hard after plant softening, many homeowners choose a water softener to reduce scale buildup on fixtures and appliances. The most recent report also shows total trihalomethanes, a disinfection byproduct, at 67 ppb against an 80 ppb limit, so some families add reverse osmosis or whole-house filtration to address chlorine taste and disinfection byproducts.
How does the Westerville Water Division monitor water quality?
The Westerville Water Division tests for bacteria, lead, copper, nitrate, fluoride, disinfection byproducts, turbidity, total organic carbon, sodium, and other substances. In its most recent lead and copper sampling, none of the 37 homes tested exceeded the lead action level, the 90th percentile lead result was 1.5 ppb, and lead was not detected at the plant tap.
