Drinking Water Testing and Certification

Idaho Bureau of Laboratories (IBL) analyzes environmental samples for chemical and microbiological contamination  and certifies environmental labs for microbiological, inorganic, organic, and radiochemical analysis.

About environmental testing

Idaho Bureau of Laboratories (IBL) analyzes environmental samples for chemical and microbiological contamination.  

IBL maintains strict guidelines regarding receipt and processing of samples. Some samples may be submitted by the public while others are accepted only from state agencies, district health departments, or law enforcement agencies.

Before submitting a sample, please consult the Bureau's Sampling and Submission Guide which provides a listing of tests performed at IBL and information on sample collection and handling procedures. Proper submission forms must accompany samples.  Call 208-334-2235 with questions about sample submission to IBL.

  • The well log database from the Idaho Department of Water Resources provides information about your specific domestic well
  • Educational materials available from the Idaho Department of Health and Welfare help you learn about common water contaminants and when to test for them.

School and daycare lead testing

IBL also offers free lead testing in drinking water for Idaho's public schools. Consult the Sampling and Submission Guide  prior to sample submission.
