Well water testing
If you own a well, its water is yours to look after. Nobody tests it for you the way a utility tests public water. There are two kinds of testing to know about, and they do different jobs.

Two kinds of testing
| Free in-home test | Certified lab test | |
|---|---|---|
| Good for | Finding what’s behind stains, smell and scale, and sizing equipment | Confirming bacteria, nitrates, arsenic and other items you can’t see or smell |
| Who does it | The local water treatment provider, at your home | Your local health district or a certified laboratory |
| Cost | Free | Varies. Some county samples run about $75–$100, and larger panels cost more. |
The free in-home test is not a substitute for lab testing. It can’t tell you whether well water meets drinking water standards. If that’s your question, use a lab.
What Ohio’s health agencies suggest
In Ohio, private water systems are regulated by the Ohio Department of Health and administered with local health districts. The department advises well owners to test for total coliform bacteria, E. coli, nitrates and arsenic every year, and any time the water’s taste, smell or appearance changes. Ohio State University Extension also publishes guidance on household well water testing.

Frequently asked questions
How often should I test my well?
Ohio health agencies recommend testing at least once a year, plus any time the taste, smell or look of the water changes or the well has been worked on.
Does the free in-home test check for bacteria?
No. It’s meant for things like hardness and iron that affect your plumbing and which equipment you need. Bacteria testing needs a properly collected sample and a lab. Your county health department can explain the process.
What does a lab test cost?
It depends on what’s tested. As an example, some Ohio health districts charge about $75–$100 for a sample from an existing private water system. Wider panels at private labs cost more. Ask your local office for its current fee.
Can I find records for my well?
Often, yes. The Ohio Department of Natural Resources keeps a searchable water well database of well logs, and your county health department may hold records too.
