Environmental Health: Water Lab Forms

Forms for Water Lab

The lab is certified to perform total coliform tests and heterotrophic place counts. The following sample forms will let you know what information you will need to provide with your water sample.

Please note that water sample results are most accurate when they are received and analyzed within 24 hours. We can analyze samples up to 40 hours old. Samples older than 40 hours will not be accurate.

For public water supply samples, the state will not accept samples over 30 hours old as valid.
