Drinking Water
  • Drinking Water Analysis Laboratory

    The DEQ laboratory will be closed on the following State of Michigan holidays in November:

    November 4, 2014  Election Day
    November 11, 2014  Veterans Day
    November 27-28, 2014  Thanksgiving holiday

    As a result, the laboratory will be unable to accept surface water bacteriological samples on Monday November 3, Monday November 10 or Wednesday November 26. Drinking water coliform samples (test code B) will be accepted on these dates preceding the holidays. Customers should also be aware that there might be some delay in the receipt of samples shipped to the laboratory during these holiday periods. This could affect the analysis of bacteriological samples.

    The Drinking Water Analysis Laboratory offers services for the analysis of drinking water quality. These services include all physical, chemical, and microbiological testing procedures currently used for this purpose by state and local water supply programs.
