Many Nebraska laboratories offer testing services that include drinking water analyses. Some of these laboratories are operated by government agencies and others are commercial laboratories. A degree of reliability and accuracy can be expected when testing is performed in an approved laboratory.

For additional information on drinking water analyses, see Drinking Water: Testing for Quality, NebGuide 907.

Laboratory Certification

The Nebraska Department of Health and Human Services administers the U.S. Environmental Protection Agency (EPA) Safe Drinking Water Act (SDWA). This includes certification of laboratories to test drinking water samples in Nebraska.

A certified laboratory must use approved testing methods and equipment and meet specific requirements outlined by the EPA. A certified laboratory may not be approved to test all potential drinking water contaminants. Certification is given to laboratories to analyze specific contaminant(s) and a laboratory must meet criteria for each analysis for which it wants to be certified.
Regulatory certification provides some assurance that the laboratory can perform water quality analyses within an acceptable range of accuracy, and will provide reliable and accurate results. It is not a guarantee that a specific water sample analysis has been or will be performed accurately.

Upon request, the Nebraska Department of Health and Human Services (DHHS) can provide information regarding all laboratories located and certified in Nebraska, and specific contaminants for which each is certified. For a full and current list of water quality parameters for which each lab has obtained certification, contact the DHHS Drinking Water Laboratory Certification Office at (402) 471-8407 or by e-mail at Laurie.wieting@nebraska.gov. The DHHS Public Health Environmental Laboratory is the only lab in the state that is certified or has a contract with a certified laboratory to test for every drinking water contaminant regulated by EPA SDWA.

Non-certified laboratories may use the same equipment and procedures as a certified laboratory. Such laboratories may provide accurate analyses, but there is no independent information about the laboratory’s ability to obtain reliable results for a particular analysis.

Certified Water Testing Laboratories in Nebraska

The laboratories listed are those located in Nebraska that are certified in Nebraska (as of December 2013) to test private drinking water samples. This list is not meant to be an endorsement of any organization. All of the laboratories listed below are currently certified to test for total coliform. Some are certified to test for additional contaminants, but the specific contaminants for which they have obtained certification varies from laboratory to laboratory. Check with laboratories at the time testing is to be done to discuss the specific tests in which you are interested.

Contacting a Laboratory

Narrow down your options after contacting the DHHS Drinking Water Laboratory Certification Office or individual laboratories to determine which laboratories are certified in Nebraska to test for the specific contaminant(s) you are considering. Then, ask individual laboratories about test fees, sampling bottles or kits, and sampling instructions. Typically, there will be a fee for each contaminant tested; however, some laboratories offer “package tests” which include testing for a number of contaminants for a specified fee. For many contaminants there are special sample containers, preservatives, and sampling procedures that must be used. Carefully follow the sampling instructions provided by the laboratory to get accurate results.

Testing Non-Drinking Water

The information in this NebGuide refers to testing water for human domestic consumption and use. There may be occasions when tests are needed to determine the suitability of water for other uses. Many of the laboratories listed above provide testing for uses in addition to domestic use. Reputable non-certified laboratories also may provide non-drinking water testing.
