Douglas County private well quality is owner homework
A Porch Note from Colorado Porch — plain-English local details for all 64 Colorado counties.
A home on a private well draws its water from the ground beneath the property, with no public utility watching over it. That convenience comes with a quieter responsibility: keeping the water free from pathogens and pollutants falls to the homeowner, not to anyone else.
Plenty of ordinary things can put that water at risk. Poorly grouted casings, shallow dug wells, and old or cracked casings can let trouble in. So can surface water intrusion, a septic system that has not been maintained, or excessive pesticide use on the land around the well. None of these announce themselves at the tap.
That last point is the catch. Clear water is not the same as tested water. A buyer can turn on a working faucet, see a steady clean stream, and assume everything is fine, when the real question is whether the well has been maintained and tested in a way that fits the property and its surroundings.
The way to answer that question is paperwork, not a glance. Ask for the well records, the maintenance history, and recent lab results before you rely on the water. And if the pump or any well equipment has been swapped out, fold a fresh test into the wrap-up of that work rather than treating it as an optional extra.
