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. Columbus reports average hardness levels ranging from approximately 5.7 to 7.3 grains per gallon (98–125 ppm), 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 participated in EPA-required PFAS monitoring and notes that federal PFAS regulations were finalized. The utility will begin compliance monitoring under the new standards and states that treatment will be installed if future sampling indicates it is necessary to meet federal requirements. 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 city’s water quality report shows fluoride levels averaging between 0.96 and 0.98 ppm, 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. The Water Quality Assurance Laboratory completed more than 70,000 analyses 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.
