Fort Irwin’s water permit requires Fort Irwin to notify the public quarterly of the following:
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 two milligrams per liter (mg/L) of fluoride may develop cosmetic discoloration of their permanent teeth (dental fluorosis).
The domestic use water provided by the Fort Irwin water system has a fluoride concentration ranging from of 1.0 mg/L to 16 mg/L. Dental fluorosis 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 use the reverse osmosis water 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 can increase your risk of developing bone disease. Some people who drink water containing arsenic in excess of the MCL over many years may experience skin damage or circulatory system problems, and may have an increased risk of getting cancer. The domestic use water provided by the Fort Irwin water system has an arsenic concentration ranging from 3.7 μg/L to 34 μg/L.
