Yes. Lewis Center is served by Del-Co Water Company, and its drinking water meets federal and state drinking water standards. Del-Co’s most recent water quality report lists no violations, and the system holds a current, unconditioned operating license.

Del-Co’s most recent water quality report does not publish hardness data, so there is no official hardness level for Lewis Center. Because Del-Co blends surface water from the Olentangy River and two reservoirs with groundwater from a Knox County well field, hardness can vary across the system. Homeowners noticing scale buildup, spotting on dishes, or soap performance issues can schedule a free in-home water test to learn their home’s exact hardness.

Del-Co’s most recent water quality report explains what PFAS are but does not include PFAS test results. 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 in-home water test.

Yes. The most recent water quality report shows fluoride averaging 1.08 ppm, with a range of 0.86 to 1.18 ppm, below the EPA maximum contaminant level of 4.0 ppm and within levels commonly used to support dental health.

Lewis Center’s drinking water comes from Del-Co Water Company, which draws surface water from the Olentangy River, O’Shaughnessy Reservoir on the Scioto River, and Alum Creek Reservoir, plus groundwater from four wells in the Knox County well field. All of these sources sit in the Upper Scioto Watershed.

Del-Co treats water at four plants: the Olentangy, Ralph E. Scott (Alum Creek), and Timothy F. McNamara (Old State) plants for surface water, and the Thomas E. Steward plant for Knox County groundwater. Together they produce nearly 13 million gallons per day, with chlorine disinfection and fluoride addition before water reaches homes and businesses.

While Lewis Center’s water meets all drinking water standards, Del-Co’s most recent report shows total trihalomethanes, a disinfection byproduct, at a highest running average of 79.95 ppb, just under the 80 ppb limit, and the herbicide atrazine was also detected at low levels (0.47 ppb against a 3 ppb limit). Many homeowners choose reverse osmosis or whole-house filtration to reduce disinfection byproducts, chlorine taste and odor, and agricultural contaminants, and a water softener can help with hardness-related issues.

Del-Co tests for bacteria, lead, copper, nitrates, fluoride, disinfection byproducts, herbicides such as atrazine and simazine, turbidity, total organic carbon, and other regulated substances. In its most recent lead and copper sampling, lead measured 0.85 ppb at the 90th percentile, and none of the 50 sites sampled exceeded the action level for either metal.
