FAQ
Additional Information On Columbus, OH Tap Water
Is Columbus tap water safe to drink?
Yes. Columbus drinking water meets federal and state drinking water standards.
Is Columbus tap water hard?
Yes. The most recent Columbus water quality report shows a system average hardness of about 115 ppm (roughly 6.7 grains per gallon), with plant averages ranging from 98 to 125 ppm (5.7 to 7.3 gpg) depending on which treatment plant serves your area. This falls within the moderately hard to hard water range and may contribute to scale buildup on fixtures, spotting on dishes, and reduced soap performance.
Is there PFAS in Columbus tap water?
Columbus took part in the EPA's fifth round of unregulated contaminant monitoring (UCMR 5), which tested for PFAS; the most recent water quality report doesn't print those results but says they're available from the city's Water Quality Assurance Lab. Federal PFAS limits have been set, and Columbus says it will meet them and install treatment if future sampling shows it's needed. Residents can contact Columbus Water & Power for additional PFAS monitoring information.
Does Columbus tap water have fluoride?
Yes. Columbus adds fluoride as part of its treatment process to help protect dental health. The most recent water quality report shows fluoride levels of 0.96 to 0.98 ppm across the city's three treatment plants, well below the EPA maximum contaminant level of 4.0 ppm.
Where does Columbus get its tap water?
Columbus draws drinking water from multiple sources. Surface water comes from the Scioto River and Big Walnut Creek, while groundwater is pumped from sand and gravel aquifers in the Scioto River Valley. Water is treated at the Dublin Road, Hap Cremean, and Parsons Avenue water plants before distribution throughout the city.
How is Columbus water treated?
Columbus uses a multi-barrier treatment process that includes coagulation, sedimentation, softening, pH adjustment, ozone treatment, granular activated carbon filtration, ultraviolet (UV) disinfection, chlorination, fluoride addition, corrosion control treatment, and continuous water quality testing before water reaches customers.
Do I need a water softener or filter in Columbus?
Because Columbus water is moderately hard to hard in many areas, some homeowners choose a water softener to reduce scale buildup and improve soap efficiency. Others install reverse osmosis systems or whole-house filtration systems to address concerns about chlorine taste, emerging contaminants such as PFAS, sediment, or overall water quality preferences. Water treatment needs can vary depending on the source water serving your neighborhood and your home's plumbing.
How does Columbus monitor water quality?
Columbus Water & Power performs extensive testing throughout the treatment process and distribution system. Its Water Quality Assurance Laboratory completed more than 70,000 analyses in the most recent reporting year and monitors contaminants including bacteria, lead, copper, nitrates, disinfection byproducts, pesticides, herbicides, turbidity, PFAS-related compounds, and other regulated and unregulated substances to ensure compliance with federal and state drinking water standards.
