Prices the lab prints, compared

Around this lab: Larimer County, CO

• Private wells: about 1,057 people, 0% of Larimer County’s 333,577 residents (USGS, 2015); rank 51 of 64 counties in Colorado by people on wells.
• At house sale: Larimer County Department of Health and Environment has a septic system rule (Larimer County Transfer of Title program (regulation section not cited on the county page)). What it requires

• 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.
• Arsenic above 10 µg/L (USGS model): about 38 private-well users (95% range 29 to 50; 2010 base), rank 39 of 64 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 32% of 164,690 housing units were built before 1980, below 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): 13 public systems serving this county reported EPA UCMR 5 results; 1 had a PFOA or PFOS sample at or above 4.0 ng/L.

County figures describe where the lab is, not the lab. Sources: USGS 2015 water use and 2017 arsenic estimates, EPA radon zones, Census ACS table B25034 (2020–2024), EPA UCMR 5 (2023–2026); details and links on the sources page.

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.
