The MDA is responsible for monitoring groundwater and surface water for pesticides and fertilizers. They also provide support to other agencies that are interested in monitoring for pesticides. As described above, the MDH is responsible for developing health-based reference values for drinking water and monitoring public water supplies. The Minnesota Pollution Control Agency (MPCA) is responsible for developing surface water regulatory standards and monitoring surface waters for non-agricultural chemicals. There are no surface water standards or reference values for the cyanazine breakdown products.

Prior to 2019, only one federal research laboratory in the nation was capable of testing for cyanazine breakdown products. In early 2019, the MDA laboratory and a private laboratory under a contract with the MDA (Weck Labs) were able to develop a method to detect and measure cyanazine breakdown products in water. Both the MDA and the contract laboratory have been conducting analysis for cyanazine breakdown products in water samples since March 2019. Starting in 2021, another private lab (Eurofins Eaton Analytical) is now capable of analyzing for the cyanazine breakdown products, bringing the total private labs to two.
