Treatment Costs
What you'll actually pay for common treatment systems in Ohio:
| System | Equipment Cost | Installation | Notes |
|---|---|---|---|
| Water softener | $800-$2,500 | $200-$500 | Essential for nearly all Ohio wells. Addresses hardness only. |
| Iron/manganese filter | $800-$2,000 | $200-$500 | Oxidation filter or greensand. Often paired with softener. |
| Point-of-use RO (kitchen sink) | $200-$500 | $100-$300 | For nitrates, lead, or other specific contaminants at one tap. |
| UV disinfection | $350-$1,500 | $200-$600 | Whole-house bacteria treatment. Bulb replacement ~$50-$100/year. |
| Whole-house carbon filter | $500-$1,500 | $200-$500 | Removes chlorine, some VOCs, taste/odor. Does NOT remove nitrates or hardness. |
| Aeration system (for methane/H2S) | $1,500-$3,000 | $300-$800 | Strips dissolved gases. Necessary for methane safety. |
Always test before you buy. A salesperson who recommends a system without seeing your water test results is not working in your interest. Know what's in your water, at what concentrations, and then match the treatment to the problem.
