Public / homeowner samples

Public samples: yes (per state)

CDPHE's 'Drinking Water Lab Certifications' report (cdphe.colorado.gov/dwlabs), column "Accepts Outside Samples": Yes. CDPHE does not say which outside samples a lab takes or on what terms; its 'Water testing services' page says "Before sending samples to another lab, please ensure you have checked its sample submission criteria". Call first. CDPHE's 'Water testing services' page (State Public Health Laboratory): "Private customer water testing bottle order form This order form is for non-water providers, such as well owners, business owners, and real estate agents, who want to test their drinking water." The same page says: "The Colorado Public Health Lab has temporarily suspended water chemistry testing." (bacterial testing remains available).

Around this lab: Denver County, CO

• Private wells: about 0 people, 0% of Denver County’s 682,545 residents (USGS, 2015); rank 63 of 64 counties in Colorado by people on wells.

• EPA radon zone (indoor air): Zone 1: highest potential (average indoor radon may be greater than 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Older homes (Census ACS 2020–2024): 55% of 359,581 housing units were built before 1980, above the state share of 40%. Homes built before 1986 are more likely to have lead solder or fittings, so test tap water for lead there.
• PFAS in public water nearby (public supply, not your well): 3 public systems serving this county reported EPA UCMR 5 results; 0 had a PFOA or PFOS sample at or above 4.0 ng/L.

Before you send a sample

Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Colorado certification program.
