Newark Water at a Glance
Water Hardness Meter — Newark
At 15 grains per gallon, Newark water is classified as Very Hard. Anything above 10.5 gpg is considered hard; Columbus-area water typically runs 15–18 gpg.
Common Water Problems in Newark
Newark water at 15 gpg causes significant scale buildup on water heaters, dishwashers, and plumbing over time. A water softener is the most effective solution.
Newark's water source contains iron levels approaching the EPA secondary standard of 0.3 mg/L. Some homeowners notice orange staining on fixtures, laundry, or toilet bowls.
Licking County's agricultural areas can contribute nitrates and other runoff contaminants to water sources. Newark's treatment plant monitors these, but an RO system provides an additional layer of protection.
Newark residents sometimes notice changes in water taste or odor during spring and summer, related to algae growth in source water and seasonal treatment adjustments.
