If you draw water from a private well in Troy, many of the usual checks are simple. You can smell for rotten eggs, watch for orange staining, and notice when the water tastes or looks off. Radium is different. It has no smell, no taste, and no color, and it is one of the few common well issues a homeowner is unlikely to notice without a lab test.
What radium is and why it shows up here
Radium is a naturally occurring radioactive element. It forms over long periods from the breakdown of uranium and thorium, which are present in many rocks and soils. In and around Troy, the limestone and dolomite bedrock can hold these minerals, and water moving slowly through deep rock can pick up radium along the way. The same deep-bedrock source appears in city water across the area, which is one reason local water professionals keep an eye on it. Homes in Troy also draw on a mix of river water and groundwater, so the source of any given well can vary from one property to the next.
Why private well owners rarely test for it
Private wells across rural Lincoln County are not regulated or tested under the Safe Drinking Water Act. No routine sampling schedule is coming to your door. The owner decides what to test, and common well checks tend to focus on bacteria, nitrate, hardness, iron, and manganese. Radium is often left off unless someone asks for it by name. A kit that reports hardness or iron will not tell you anything about radium, so the test has to be requested on purpose.
How to test a Troy well for radium
- Contact a certified drinking water lab and ask for a radium test by name. Ask whether they report the specific radium isotopes separately or as a combined total.
- Request the lab's sample bottles, written collection instructions, and chain-of-custody form. Follow the instructions exactly, including any requirement to run the water for a set time first.
- Collect the sample from a cold tap that receives water straight from the well, before any softener, filter, or storage tank. Treated water will not show what the source contains.
- Ship or drop off the sample within the lab's required window, and keep a copy of all the paperwork.
- Repeat the test if the first result is high, or if the well has been newly drilled, recently repaired, or disturbed by nearby work.
Reading the lab report
A lab report lists each result with its unit and a reporting limit. Each result is typically compared against drinking water standards, so check how the report presents that comparison.
- Check the reporting limit. A result listed as not detected means the lab did not find the substance above that limit.
- Confirm whether the report shows each radium isotope separately, a combined total, or both.
- Note the sample date and the tap location written on the report.
- Keep the report with your well records. A future buyer, lender, or inspector may ask for it.
If the result is above the standard
Do not try to remove radium with a homemade method. Start by talking with a licensed water treatment professional and with your state environmental agency about the options available for your property. The right approach depends on your water chemistry, how much water your household uses, and whether you need treatment for the whole house or only one tap. Ask any professional to explain how they will confirm the system works through follow-up testing, and how any waste material from the process will be handled.
Next steps for a Troy homeowner
If you live in Troy and have never tested your well for radium, schedule one test this season and file the report with your other records. Retest after major well work, a pump replacement, or any change to the well area. If your home runs on city water in Troy instead, the utility's yearly water quality report is the place to check, and that question is separate from testing your own well.
