Water Testing Decision Tree

The following factsheet has information on labs for microbial water testing and for pH, salinity, nitrates, nutrients, etc. This decision tree includes information for those testing for produce growers, irrigating crops (other than produce), watering livestock and poultry, and household use.

Microbial Water Testing

Kansas State University and the University of Missouri continue to offer free microbial water testing to all fruit and vegetable growers in KS and MO, even in light of the COVID-19 situation. We can provide this free testing until our generous grant funding from the USDA National Institute of Food and Agriculture (grant 2019-70020-30358) runs out.

 

For Kansas Growers

For having bottles mailed to you and for coordinating a return mailing or drop-off at the Manhattan campus, please contact KaWang Li at kwli@ksu.edu or 785-532-1298. For coordinating logistics with the Olathe campus contact Dr. Manreet Bhullar at msbhullar@ksu.edu. Please include your name, address, phone number, and a brief description of your water source. It is highly encouraged to pull a sample every month for 3 months to get a better idea of your water quality, versus one individual snapshot in time. Samples need to be received on ice and within 24 hours of the sample being taken.

For questions about proper sampling procedures or to review your water test results, please contact Katelynn Stull at kjstull@ksu.edu or 913-307-7394.

For Missouri Growers

Water sample kits can be obtained from most local public health departments in Missouri, as well as in some other locations throughout Missouri. Samples can be returned to most local public health departments in Missouri (on ice, within 24 hours of taking the sample). Due to the COVID-19 situation, please contact your local public health department before going to their office to pick up bottles or drop off samples to confirm their procedures and hours of operation. More information on collecting water samples and how to submit them in Missouri is available in the following documents:
