d. A control chart approach that gives control limits for each constituent.
e. Another statistical test method that meets the performance standards specified below. Based on the justification submitted to the department, the director may approve the use of an alternative test. The justification must demonstrate that the alternative method meets the performance standards in subdivision 2 of this subsection.
a. The statistical method used to evaluate groundwater monitoring data shall be appropriate for the distribution of monitoring parameters or constituents. If the distribution is shown by the owner or operator to be inappropriate for a normal theory test, then the data shall be transformed or a distribution-free theory test shall be used.

c. If a control chart approach is used to evaluate groundwater monitoring data, the specific type of control chart and its associated parameter values shall be protective of human health and the environment. The parameters shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.
d. If a tolerance interval or a predictional interval is used to evaluate groundwater monitoring data, the levels of confidence and, for tolerance intervals, the percentage of the population that the interval must contain, shall be protective of human health and the environment. These parameters shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.
e. The statistical method shall account for data below the limit of detection with one or more statistical procedures that are protective of human health and the environment. Any estimated quantitation limit (EQL) that is used in the statistical method shall be the lowest concentration level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions that are available to the landfill.
f. If necessary, the statistical method shall include procedures to control or correct for seasonal and spatial variability as well as temporal correlation in the data.
e. All approved variances, well subsets, wetlands, or other such director/department approvals.
