Disclaimer:

The Department of Environmental Quality (DEQ), Pollution Prevention and Technical Assistance Section, of the Environmental Science & Services Division (ESSD), compiled the information in this directory, in conjunction with the Michigan Environmental Laboratory Association and various DEQ Divisions. No attempt is made by the DEQ to verify the accuracy of the information submitted by the environmental laboratories via the “Environmental Laboratory Questionnaire.” This directory summarizes or reproduces the information supplied by participating environmental laboratories. The listing or omission of any laboratory does not imply endorsement or disapproval by the DEQ. Presently, there are no laboratory certification requirements for environmental laboratories in Michigan. However, drinking water laboratories (bacteriological & chemical) are required to be certified. In Michigan, drinking water laboratories are required to meet the laboratory certification requirements of the ESSD. The DEQ makes no warranties, either expressed or implied, as to the competency, qualifications or professional abilities of any environmental or Whole Effluent Toxicity (WET) laboratory listed in this directory. The DEQ, by producing this directory, makes no representation that the companies listed are, or are not, in compliance with applicable state and federal environmental laws or regulations.
