Section 31.02. Groundwater test results; use by department.

 

(1)   Use of official groundwater test results. An official groundwater test result is presumed to be reliable for purposes of regulatory or enforcement action under this chapter whether or not the department collected or analyzed the official groundwater sample.

(2)   Use of unofficial groundwater test results. A regulatory or enforcement action under this chapter may be based on a groundwater test result which is not an official groundwater test result only if the department determines that the unofficial groundwater test result is reliable for purposes of the regulatory or enforcement action.

Pursuant to ss. 160.21 (2) (e) and 160.27 , Stats., the department shall enter into a memorandum of understanding with the department of natural resources to ensure the reliability of official groundwater test results used by the department for purposes of regulation and enforcement under this chapter. The memorandum of understanding shall govern the reporting and certification of official groundwater test results to the department by the department of natural resources. It shall also govern the collection, handling and analysis of official groundwater samples by the department of natural resources or its designated agents. The memorandum of understanding shall include:

(4)   Department contracts with agents designated to collect or analyze official groundwater samples. Every person or entity designated to collect or analyze an official groundwater sample as the agent of the department, rather than as the agent of the department of natural resources, shall first enter into a written contract with the department. Contracts shall include specific standards for the collection, handling and analysis of official groundwater samples, to ensure the reliability of official groundwater test results used by the department for purposes of regulation and enforcement under this chapter. Agents contracting directly with the department shall be held to the same requirements which are applicable to agents designated by the department of natural resources pursuant to a memorandum of understanding under sub.
