ATCP 31.02ATCP 31.02 Groundwater test results; use by department. ATCP 31.02(1)(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. ATCP 31.02(2)(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.
