Geauga County well water

Most Geauga homes are on their own water supply

There’s no utility testing your water, no annual report in the mail, and no one who will tell you when something changes. A private well is a small water system you own — which is a reason to test it, not a reason to worry about it.

What the USGS found

In 2009 the U.S. Geological Survey sampled domestic wells across Geauga County and published the results in 2015. The headline isn’t arsenic, and it isn’t bacteria. It’s iron and manganese: they exceeded aesthetic standards in more wells than anything else measured.

Iron and manganese are secondary contaminants. That’s a specific term — it means they’re regulated for staining, taste, and odor rather than for health. Orange staining in a toilet tank is a nuisance and a laundry problem. It isn’t a medical finding, and anyone who tells you otherwise is selling something.

Arsenic is different. It exceeded the benchmark in two of sixteen sampled wells, and arsenic is a genuine health-based standard. It’s also invisible, tasteless, and undetectable by any field kit — the only way to know is a certified laboratory test.

What this means for your well specifically

It doesn’t mean your well matches the study. Sixteen wells is a small sample across a county with widely varying geology, and your neighbor’s results don’t predict yours. What the study justifies is testing, not a preemptive purchase.

A reasonable baseline for a Geauga well is total coliform bacteria, nitrate, and arsenic, plus iron, manganese, hardness, and pH. Bacteria and nitrate are worth repeating annually. Arsenic is worth doing once, and again if anything about the well changes.

What treatment is actually indicated

• Iron, manganese, or rotten-egg smell: an air-injection filter oxidizes and filters them without chemicals. This is the common Geauga case.
• Hardness: an ion-exchange softener, sized from your measured grains per gallon and your household size — not from a chart.
• Arsenic: dedicated adsorptive media, or reverse osmosis at the kitchen tap if the concern is drinking water only. Which one depends on the form the arsenic takes, which is why this follows a lab result rather than a sales call.
• Bacteria: ultraviolet disinfection, installed last in the train and only on water that’s already clear.

If your test comes back clean, you don’t need any of it, and we’ll tell you so in writing.

The equipment behind those options is on our well water systems page, and hardness on its own is on water softeners. Which of them applies to your well is a question the free in-home test answers and a brochure can’t.
