Note:
Sources, including the following as updated, likely contain methods that are acceptable for testing under this chapter: The EPA, the department, Standard Methods for the Examination of Water and Wastewater, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods – SW-846, American Society for Testing and Materials, and the U.S. Geological Survey Agency.
NR 149.02(7)(b)

NR 149.02(7)(c)
(c) When a laboratory incorporates a procedure that is neither expressly permitted nor prohibited by the method, the department will assess the scientific validity of the procedure to determine if the procedure is within the scope of the method. The underlying chemistry of the method shall remain unchanged. The department may seek the advice of the council in making determinations under this paragraph.
NR 149.02 Note
Note:
For example, if a digestion time of 30 minutes is required, the laboratory is not to use less time for digestion. A second example, when a minimum volume of solvent is required to extract a specific amount of sample, then less solvent is not to be used unless the ratio of extraction solvent to sample amount is maintained.
