1550.3210 PRODUCT QUALITY.

Subpart 1.

Standards.

Bottled water must be from an approved source and must not contain anything in a quantity that may be injurious to health. Bottled water must meet the standards in Minnesota Statutes, section 31.101, subdivision 8, and other rules adopted by the department.

Subp. 2.

Microbiological quality.

Bottled water must meet the standard of microbiological quality in item A or B if a sample of analytical units of equal volume is examined by the methods described in applicable sections of "Standard Methods for the Examination of Water and Wastewater," 20th edition (1998), published by the American Public Health Association. The commissioner may accept other official methods of analysis when published in "Standard Methods for the Examination of Water and Wastewater." That publication is incorporated by reference, is not subject to frequent change, and is available through the Minitex interlibrary loan system or from the American Public Health Association, 800 I Street, Washington, D.C. 20001-3710.

A.

Multiple-tube fermentation method. Not more than one of the analytical units in the sample may have a most probable number of 2.2 or more coliform organisms per 100 milliliters and no analytical unit may have a most probable number of 9.2 or more coliform organisms per 100 milliliters.

B.

Membrane filter method. Not more than one of the analytical units in the sample may have 4.0 or more coliform organisms per 100 milliliters and the arithmetic mean of the coliform density of the sample may not exceed one coliform organism per 100 milliliters.

Subp. 3.

Physical quality.

Bottled water must meet the standards of physical quality in items A to C if a composite of analytical units of equal volume from a sample is examined by the method described in applicable sections of "Standard Methods for the Examination of Water and Wastewater," 20th edition (1998), which is incorporated by reference in subpart 2.
