(1)
				  Community water supplies that measure fluoride above 2.0 mg/l as determined by
				  the last single sample taken under R 325.10710, but do not exceed the maximum
				  contaminant level (MCL) of 4.0 mg/l for fluoride under R 325.10604c, shall

				  notice shall be provided as soon as practical but not later than that of a tier

				  sent to all new billing units and new customers under R 325.10406 (1) and to

(2) The form and manner of the public notice,
				  including repeat notices, shall follow the requirements for a tier 3 public
				  notice in R 325.10404 (3), (4) (a), and (4) (c).
(3) The notice shall contain the following
				  language, including the language necessary to fill in the blanks: "This is an
				  alert about your drinking water and a cosmetic dental problem that might affect
				  children under 9 years of age. At low levels, fluoride can help prevent
				  cavities, but children drinking water containing more than 2.0 milligrams per
				  liter (mg/l) of fluoride may develop cosmetic discoloration of their permanent
				  teeth (dental fluorosis). The drinking water provided by your community water
				  system [name] has a fluoride concentration of [insert value] mg/l.
Dental fluorosis, in its moderate or severe forms, may
					 result in a brown staining and/or pitting of the permanent teeth. This problem
					 occurs only in developing teeth, before they erupt from the gums. Children
					 under 9 should be provided with alternative sources of drinking water or water
					 that has been treated to remove the fluoride to avoid the possibility of
					 staining and pitting of their permanent teeth. You may also want to contact
					 your dentist about proper use by young children of fluoride containing
					 products. Older children and adults may safely drink the water.
Drinking water containing more than 4.0 mg/l of fluoride
					 (the U.S. Environmental Protection Agency's drinking water standard) can
					 increase your risk of developing bone disease. Your drinking water does not
					 contain more than 4.0 mg/l of fluoride, but we're required to notify you when
					 we discover that the fluoride levels in your drinking water exceed 2.0 mg/l
					 because of this cosmetic dental problem For more information, please call [name
					 of water system contact] of [name of community water system] at [phone number].
					 Some home water treatment units are also available to remove fluoride from
					 drinking water. To learn more about available home water treatment units, you
					 may call NSF International at 1-877-8 NSF HELP."
