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 PFAS in Colorado
EPA's 4.0 ng/L limits for PFOA and PFOS cover public water, not private wells, and its May 2026 proposals to roll back four other PFAS limits are not final. Read our PFAS explainer.
Colorado guidance that mentions PFAS:
- 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]
- Anyone with a private well in Colorado can apply to CDPHE's PFAS Testing and Assistance Program (PFAS TAP) for free PFAS testing: a kit is mailed to you, you collect the sample and mail it back with a prepaid label. Households that use the well for drinking and cooking and have PFAS above EPA's drinking water standard can get a free filter dispenser and one year of replacement filters; results from an independent lab test can also qualify. CDPHE says the program is available while supplies last. In 2026 it is doing targeted outreach with Boulder County and the San Luis Valley. [2]
About 286,474 people in Colorado used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [3] 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.
