This test measures the concentration of radon present in your water sample.

Who it’s for: Maine’s granite bedrock makes radon in well water common, and you cannot see, smell, or taste it. If you have never tested for radon, this answers it.

How it works: Order online and we ship your kit, or pick one up at any of our 9 drop-off locations across Maine. Collect your sample (instructions included, about 10 minutes), then return it to a drop-off location or ship it back. You get plain-English results by email, with numbers you can act on.
