1. Water analysis.
				A chemical analysis of the water supply, made according to accepted water

				conditioning equipment. For those waters containing a hardness of four hundred
				milligrams per liter [23 grains per gallon] and or sodium in excess of one
				hundred milligrams per liter (6 grains per gallon) of calcium carbonate. The
				compensate hardness to determine the increased amount of resin needed.
2. Capacity and sizing. To assure
				adequate softening capacity, the following formula may be used (based upon
				daily water needs per person of fifty gallons [189.27 liters]) to determine the
				required size of manual and semiautomatic softeners:
G x P x H x F = Softening capacity requirements in grains of
				  hardness.
Where "G" is fifty gallons (daily needs per person).
Where "P" is the number of persons to occupy dwelling.
Where "H" is the hardness of the water supply expressed in
				  grains per gallon, and "F" is the desired frequency of regeneration in days.
Note: G = twenty-eight gallons if water closets are not
				  supplied with softened water.
G = twenty gallons if only hot water is to be softened.
3. The following table
				supplies the ratio of occupancy to the number of bedrooms within the dwelling
				to be used with the formula supplied in subsection 2 in determining adequate

History.
In 1929 the legislative assembly enacted the Podiatry Practice Act,
				which is codified as North Dakota Century Code chapter 43-05. The chapter
				provides for a board of podiatric medicine.
2.
Function.
The function and
				responsibility of the board is to examine and license qualified applicants for
				licensure, ensure the continuing qualifications and general educational
				background of podiatrists, determine discipline for podiatrists who violate
				general statute or this title, regulate the practice of podiatric medicine in
				North Dakota, and perform such other duties as may be required by general
				statute or this title.
3.
Board membership.
The board consists of six members appointed by
				the governor. Four of the members are doctors of podiatric medicine. One member
				is a doctor of medicine. One member is designated as a public member. The board
				members annually elect by majority vote from the board membership the
				president, vice president, and secretary-treasurer and such other officers as
				are established by the board. Members of the board who are doctors of podiatric
				medicine shall serve four-year terms arranged so that no more than two terms
				expire each year.
