Water testing




If you are testing for semivolatile organic compounds (SVOCs), volatile organic compounds (VOCs), haloacetic acids (HAAs), or trihalomethanes (TTHMs), review the organics water testing schedule as these are only processed once at a month at the State Lab. Order supplies and submit tests accordingly. 

Our Chemistry and Environmental Microbiology programs work together to test water for the state of Colorado. Below you will find links for homeowners that desire testing and for labs meeting compliance for testing drinking water throughout the state.

Water Testing Turnaround Times (How long will it take to get my results)

*Customers that order Coliform testing will often receive two separate reports. When water samples are received at the lab - testing for Coliform Bacteria is completed within 48 hours. Customers receive this report first since this test has a rapid turn around time. The remaining results are sent between 2 to 4 weeks depending on the test. If Coliform is not ordered or a part of a testing package then the customer receives one report as opposed to two separate reports. Learn more about the turnaround time for testing here.
Please note: We no longer perform testing on radiochemicals in water.
