How the Colorado list marks public samples (whole list). Per lab, from CDPHE's column "Accepts Outside Samples": Yes means the lab takes samples from outside its own organisation, so call first to ask about a household sample, its bottles and its fees; No (utility and municipal labs that test only their own system's water) is shown as not accepting homeowners' samples. CDPHE's 'Water testing services' page sends well owners to this list: "Refer to the list of other accredited laboratories that may be able to accept your samples."
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for lead in Colorado
On a private well, lead almost always comes from the metal the water touches on its way to your glass, and corrosive water decides how much. Read our lead explainer.
Colorado guidance that mentions lead:
- Colorado's health department (CDPHE) recommends testing every year for total coliform bacteria, total dissolved solids, nitrate/nitrite and pH, and every 3 to 5 years for arsenic, copper, fluoride, hardness, iron, lead, manganese and uranium. For a new well or a well with no known testing, it lists a broader panel that includes PFAS and a volatile organic compound (VOC) screen. It says more frequent testing may be needed if pregnant or breastfeeding people, small children or elderly adults drink the water. [1]
About 286,474 people in Colorado used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [2] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Colorado.
