The Inyo County Water Lab is certified by the State of California ELAP to conduct total coliform and E. coli bacterial analyses of drinking water, surface waters, and recreational waters.

SAMPLE ACCEPTANCE SCHEDULE: Samples may be dropped off at one of the two locations mentioned below during the following hours:

  • Independence Lab:  Monday through Wednesday, 9-4 and Thursday 9-12
  • Bishop County Services Building: Monday through Wednesday, 8-5

Samples delivered outside of the drop off hours (above) will not be analyzed except in the case of a public health emergency (i.e., a public water system which has had an E. coli positive sample result, or during a disaster or other emergency situation) and only if pre-approved by this office. Additional charges may apply.

Please feel free to call us if you have any questions or comments at (760) 878-0234. If you will be new to water sampling, our staff will be happy to train you on the proper sampling procedures: how to fill out lab slips, where to sample, when to sample and the preservation and hold times for your samples. So just give us a call.
