Well Water Treatment for Central Ohio Homeowners

Central Ohio well water is harder, higher in iron, and more variable than city water. We test your well first and build a treatment system around what's actually in it.

Common Central Ohio well water problems

Very hard water (20–28 gpg)

Central Ohio well water is significantly harder than city water. Scale builds up faster on appliances, pipes, and fixtures.

Iron staining

Orange stains in sinks, toilets, and laundry are the most visible sign of iron in well water. Iron above 0.3 ppm requires treatment.

Rotten egg smell (hydrogen sulfide)

Common in Delaware, Licking, and Fairfield County well water. Requires air injection or aeration treatment.

Bacteria (coliform / E. coli)

Well water is not treated by a municipality. Annual bacteria testing is recommended. UV disinfection provides continuous protection.

Nitrates

Agricultural runoff can introduce nitrates into shallow wells. Nitrates above 10 ppm are a health concern, especially for infants.

Manganese

Black or dark brown staining on fixtures and laundry. Often found alongside iron in Central Ohio geology.

Our well water treatment approach

Well water treatment is not one-size-fits-all. A home in Galena with 25 gpg hardness and 8 ppm iron needs a completely different system than a home in Sunbury with 20 gpg hardness and no iron. We test your well water first, then design a system that addresses your specific water chemistry — not a generic package.

A typical Central Ohio well water system

1
Sediment pre-filter

Removes sand, silt, and particulates that can damage downstream equipment

2
Air injection iron filter

Removes dissolved iron, manganese, and hydrogen sulfide without chemicals

3
Water softener

Removes hardness minerals (calcium and magnesium) that cause scale

4
UV disinfection

Kills bacteria, viruses, and other pathogens without chemicals

5
Under-sink RO (optional)

Final polishing for drinking and cooking water

Frequently Asked Questions

How is well water different from Columbus city water?

Columbus city water is treated by the Columbus Division of Water before it reaches your home. Well water is untreated — you are responsible for your own water quality. Well water in Central Ohio is typically harder (20–28 gpg vs. 15–18 gpg for city water), higher in iron, and may contain bacteria, nitrates, or sulfur that city water does not.

How often should I test my well water?

The EPA recommends testing well water annually for bacteria (coliform) and nitrates, and every 3–5 years for a full panel including hardness, iron, pH, and other parameters. If you notice a change in taste, odor, or color, test immediately.

Do I need a whole-house treatment system for well water?

It depends on what's in your water. Some wells in Central Ohio have excellent water quality that needs minimal treatment. Others have high iron, hardness, and bacteria that require a multi-stage system. A free water test tells you exactly what you're dealing with.

What areas of Central Ohio have the worst well water?

Delaware, Licking, and Fairfield County well water tends to be the hardest and highest in iron. Rural areas of Knox and Morrow County also commonly have high iron and sulfur. That said, well water quality varies significantly even within the same township.
