Definitions. 1. Adjusted fluoridated water system shall mean a public water system that adjusts the fluoride concentration in the drinking water to the optimal level for consumption (within the recommended control range). 2. Community Water System (CWS) shall mean any water system serving piped water for human consumption to fifteen (15) or more individual service connections used year- round by consumers or regularly serving twenty-five (25) or more individual consumers year-round, including, but not limited to, any collection, pretreatment, treatment, storage and/or distribution facilities or equipment used primarily as part of, or in connection with such system, regardless of whether or not such components are under the ownership or control of the operator of such system. 3. Department shall mean the Mississippi State Department of Health. 4. Entry point shall mean a location following one or more finished (fluoridated) water sampling points but prior to the beginning of the distribution system of the public water system. 5. Natural fluoride content shall mean the concentration of fluoride in milligrams per liter (mg/L) that is present in the water source from naturally occurring fluoride sources. 6. Optimal fluoride level in Mississippi shall mean the amount of fluoride in water that is found naturally or adjusted should be within a recommended control range of 0.6-1.2 parts per million fluoride (ppm) with the optimal fluoride level being 0.7 ppm. 7. Parts per million shall mean a unit of measurement that is equivalent to 1 milligram per liter (mg/L) where the density of the liquid measured is 1.0 gram per cubic centimeter (the density of water is 1.0). 8. Public water system (CWS) means a system for the provision to the public of water for human consumption through pipes or, after August 5, 1998, other constructed conveyances, if such system has at least fifteen service connections or regularly serves an average of at least twenty-five individuals daily at least 60 days out of the year. 9. Raw water is defined as water that has not been treated or had fluoride injected into it by the CWS and that contains only naturally occurring levels of fluoride.
