A certified laboratory must be used for any testing required by the department's Public Drinking Water Branch. Analysis of water samples from private residences or private wells does not have to be done by a certified laboratory. There are other laboratories capable of performing analyses of private water samples in addition to the laboratories included on this list. The other laboratories have chosen not to go through our certification process, but may produce equivalent results if they have adequate quality assurance or quality control in place.
*For a list of microbiological laboratories, visit Certified Microbiological Laboratories.
Laboratory Certification
For information about how to become a certified chemical laboratory, contact the department's Environmental Services Program at 573-526-3315 or email laboratorycertification@dnr.mo.gov
Search Current List of Certified Chemical Laboratories
The below list identifies all laboratories certified by the department to perform drinking water analyses for compliance purposes in the State of Missouri. Laboratories listed as commercial do perform analyses for hire. It is suggested to contact multiple labs for the best pricing for the testing parameters desired.
