NR 809.957(3) (3)Special notice standard language. 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 milligrams per liter (mg/l) of fluoride may develop cosmetic discoloration of their permanent teeth known as 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 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 mg/l of fluoride, but we are required to notify you when we discover that the fluoride levels in your drinking water exceed 2 mg/l because of this cosmetic dental problem. For more information, please call [name of the public 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.

Appendix A Footnotes
1 Violations and other situations not listed in this table, for example, reporting violations and failure to prepare Consumer Confidence Reports, do not require notice, unless otherwise determined by the department. The department may also require a more stringent public notice tier, for example, Tier 1 instead of Tier 2 or Tier 2 instead of Tier 3, for specific violations and situations listed in this Appendix, as authorized under s. NR 809.951(1) and s. NR 809.952 (1).
2 MCL--Maximum contaminant level, MRDL—Maximum residual disinfectant level, TT—Treatment technique.
3 The term Violations of National Primary Drinking Water Regulations is used here to include violations of MCL, MRDL, TT, monitoring and testing procedure requirements.
4 Failure to test for E. coli is a Tier 1 violation if testing is not done after any repeat sample tests positive for coliform. All other total coliform monitoring and testing procedure violations are Tier 3.
5 Water supplier for public water systems that violate the turbidity MCL of 5 NTU based on an average of measurements over 2 consecutive days shall consult with the department within 24 hours after learning of the violation. Based on this consultation, the department may subsequently decide to elevate the violation to Tier 1. If a water supplier is unable to make contact with the department in the 24-hour period, the violation is automatically elevated to Tier 1.
6 Water supplier for public water systems with a treatment technique violation involving a single exceedance of a maximum turbidity limit under the Surface Water Treatment Rule or the Interim Enhanced Surface Water Treatment Rule are required to consult with the department within 24 hours after learning of the violation. Based on this consultation, the department may subsequently decide to elevate the violation to Tier 1. If a water supplier is unable to make contact with the department in the 24-hour period, the violation is automatically elevated to Tier 1.
7 Most of the requirements of the Interim Enhanced Surface Water Treatment Rule (63 FR 69477) become effective January 1, 2002 for public water systems using surface water or groundwater under the direct influence of surface water serving at least 10,000 persons. However, s. NR 809.77 has some requirements that become effective as early as April 16, 1999. The Surface Water Treatment Rule remains in effect for public water systems serving at least 10,000 persons even after 2002; the Interim Enhanced Surface Water Treatment Rule adds additional requirements and does not in many cases supersede the Surface Water Treatment Rule.
8 Failure to take a confirmation sample within 24 hours for nitrate or nitrite after an initial sample exceeds the MCL is a Tier 1 violation. Other monitoring violations for nitrate are Tier 3.
9 Public water water systems using surface water or groundwater under the direct influence of surface water community and non-transient non-community systems serving greater than or equal to 10,000 must comply with the new disinfection byproducts MCLs, disinfectant MRDLs, and related monitoring requirements beginning January 1, 2002. All other community and non-transient non-community systems must meet the MCLs and MRDLs beginning January 1, 2004. Public water systems using surface water or groundwater under the direct influence of surface water transient non-community systems serving 10,000 or more persons and using chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2002. Public water systems using surface water or groundwater under the direct influence of surface water transient non-community systems serving fewer than 10,000 persons and using only groundwater not under the direct influence of surface water and using chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2004.
10 If any daily sample taken at the entrance to the distribution system exceeds the MRDL for chlorine dioxide and one or more samples taken in the distribution system the next day exceed the MRDL, Tier 1 notification is required. Failure to take the required samples in the distribution system after the MRDL is exceeded at the entry point also triggers Tier 1 notification.
11 Failure to monitor for chlorine dioxide at the entrance to the distribution system the day after exceeding the MRDL at the entrance to the distribution system is a Tier 2 violation.
12 Some public water systems must monitor for certain unregulated contaminants listed in s. NR 809.25.
13 Other waterborne emergencies require a Tier 1 public notice under 40 CFR 141.202(a) or s. NR 809.951 (1) (b) 8. for situations that do not meet the definition of a waterborne disease outbreak given in 40 CFR 141.2 or s. NR 809.04 (90) but that still have the potential to have serious adverse effects on health as a result of short-term exposure. These could include outbreaks not related to treatment deficiencies, as well as situations that have the potential to cause outbreaks, such as failure or significant interruption in water treatment processes, natural disasters that disrupt the water supply, chemical spills, or unexpected loading of possible pathogens into the source water.
14 The department may place other situations in any tier they believe appropriate, based on threat to public safety.
15 Failure to collect three or more samples for Cryptosporidium analysis is a Tier 2 violation requiring special notice as specified in section 141.211. All other monitoring and testing procedure violations are Tier 3. - See PDF for table PDF
Appendix B Footnotes:
1 MCLG--Maximum contaminant level goal.
2 MCL--Maximum contaminant level.
3 For public water systems analyzing at least 40 samples per month, no more than 5.0 percent of the monthly samples may be positive for total coliforms. For public water systems analyzing fewer than 40 samples per month, no more than one sample per month may be positive for total coliforms.
4 There are various regulations that set turbidity standards for different types of public water systems, including 40 CFR 141.13, the 1989 Surface Water Treatment Rule, and the 1998 Interim Enhanced Surface Water Treatment Rule. The MCL for the monthly turbidity average is 1 NTU; the MCL for the 2-day average is 5 NTU for public water systems that are required to filter but have not yet installed filtration (40 CFR 141.13).
5 NTU--Nephelometric turbidity unit.
6 There are various regulations that set turbidity standards for different types of public water systems, including 40 CFR 141.13, the 1989 Surface Water Treatment Rule, and the 1998 Interim Enhanced Surface Water Treatment Rule. Systems subject to the Surface Water Treatment Rule (both filtered and unfiltered) may not exceed 5 NTU. In addition, in filtered systems, 95 percent of samples each month shall not exceed 0.5 NTU in public water systems using conventional or direct filtration and shall not exceed 1 NTU in public water systems using slow sand or diatomaceous earth filtration or other filtration technologies approved by the department.
