What we do
Colorado’s Water Quality Control Commission requires compliance drinking water testing for wastewater companies, water providers, and other businesses who are supplying water to the public or discharging waste water to the environment.
Submitting a water sample to the State Lab (step-by-step instructions)
Ordering bottles from the lab:
Bottle order form for compliance testing
This order form is for water providers and wastewater companies.
Water samples collected in other bottles will not be accepted because they may be contaminated.
Water testing supplies are free of charge and will be sent to you via FedEx.
The lab requires payment for water testing at the time of submission.
The cost for a rush order is twice the test cost (excluding bacteria test costs).
