Quarterly domestic water notice

Updated: 10 August 2012

Fort Irwin’s Water System is operated under a privatization contract with CH2MHill. As the system ownership is not transferred to CH2MHill, compliance responsibilities still reside with the U.S. Army.

Fort Irwin has two water systems. A Reverse Osmosis or RO System and a domestic use system or DU system. The domestic use (DU) water is higher than the California standard in Fluoride (Maximum Contaminate Levels, MCL = 2 mg/L). The Domestic Use water is also higher than both the U. S. Environmental Protection Agency (US EPA) and State of California standard of Arsenic (MCL 10 µg/L). DU water is intended for use in washing, cleaning, irrigation, and other non potable uses. Both arsenic and fluoride in our water comes from erosion of natural deposits.

Fort Irwin treats a portion of the DU water at our reverse osmosis water treatment plant. The Reverse Osmosis treatment process removes contaminates including Fluoride and Arsentic and ensures our water meets all State and Federal Safe Drinking Water standards. The RO water should be used for drinking and cooking.

The RO system is visible in housing or your work space as either a RO water tab (shown at left) usually in the kitchen or a water fountain (shown at right). Areas that do not have RO water are provided with bottled drinking water.

Fort Irwin is in the process of contracting for design-build of a new Water Treatment Facility. Our goal is that by the end of the year 2013, we will begin constructing the new water treatment plant. By 2016 all water provided will meet or exceed the Federal and State MCLs.

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 nine 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 (dental fluorosis). The Domestic Use (DU) water provided by Fort Irwin water system has a fluoride concentration ranging from of 0.8 mg/L to 10 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 nine should use the RO 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 (DU) water provided by Fort Irwin water system has a arsenic concentration ranging from not detected (ND) to 34 µg/L.

For more information, please contact Water Resources Manager, Fort Irwin DPW, at 760-380-4987 or P.O. Box 105085, Bldg 602, Fifth St. Fort Irwin, CA 92310-5085. If you have questions concerning Fort Irwin Water System operation contact CH2MHill 760-386-9706. 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 the California Department of Health Services Water Treatment Device Unit at (916) 323-5600.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in appartments, nursing homes, schools, and buisnesses). You can do this by posting this public notice in a public place or distrubution copies by hand or mail.


Anuncio publico trimestral de la calidad del agua domestica

El sistema de agua de Fort Irwin es operado bajo un contrato de privatización con la Compañía CH2MHill. Porque el sistema continua siendo propiedad del gobierno la responsabilidad de cumplir con los requisitos de sanidad reside con el gobierno.

Fort Irwin tiene dos sistemas de agua. Uno de agua filtrada para tomar y otro sin filtrar para uso domestico. El agua del sistema para uso domestico tiene un contenido de Fluor mas alto que el nivel permitido por el Estado de California (Nivel Maximo de Contenido – (MCL = 2 mg/L).

El agua para uso domestico es también más alta que el nivel de arsenico permitido por la Agencia de la Protección del Ambiente de Los Estados Unidos (EPA) y el estándar del Estado de California (MCL 10 ug/L). El agua del sistema para uso domestico debe ser usada para lavar ropa, limpiar los pisos, regar las plantas, y otros cosas para las que no necesiten agua potable.

Fort Irwin filtra una porción del agua en la planta de filtración central. El proceso de filtración remueve contaminantes incluyendo Fluor y Arsénico y asegura que el agua potable cumpla los requisitos de sanidad de los standares Federales y Estatales. El agua potable debe ser usada para tomar y para cocinar. El arsénico y el fluor en nuestra agua viene de la erosión de depósitos naturales.

El agua potable es distribuida a su vivienda y a los sitios de trabajo y puede ser identificada por la llave del agua (foto de la izquierda) o en las fuentes de tomar agua (foto de la derecha). A los sitios que el sistema no llega se le provee agua de botella.

Esperamos que para el fin de ano del 2016 el agua consumida cumpla o supere los estándares de sanidad Federales y Estatales.

El Permiso Gubernamental bajo el cual Ft Irwin opera requiere que el público sea notificado acerca de lo siguiente.

Esta es una alerta acerca del agua que se ingiere y que puede causar problemas dentales cosméticos a los niños de menores de nueve anos de edad. A niveles bajos, el fluor ayuda a evitar las cavidades dentales pero niños menores de nueve anos no deben de tomar agua que contenga mas de 2 miligramos de fluor por litro para evitar la descoloralizacion de las dientes permanentes (Fluorosis Dental). El agua para uso domestico en Ft Irwin contiene fluor que varia de 0.8 miligramos por litro (mg/L) hasta 10 mg/L.

Fluorosis dental puede resultar en manchar los dientes del color marron e o tambien en pequenas fracturas de las dientes permanentes. Este problema solo ocurre durante la etapa de desarrollo de los dientes antes de que broten de las encias. Ninos menores de nueve anos deben de tomar siempre el agua del sistema filtrado para evitar la posibilidad de manchar los dientes o de las pequenas fracturas de los dientes permanentes. Tambien Usted debe consultar con su dentista acerca del uso de productos que contengan fluor. El agua para uso domestico no afecta a los ninos mayores de nueve anos ni a los adultos.

Agua con un contenido en exceso de 4 miligramos de fluor por litro puede aumentar el riesgo de enfermedads en los huesos.

Algunas personas que toman agua que contiene arsénico mas alto que el estandar (MCL=10 µg/L) por muchos años pueden afectar la piel o problemas de sistema circulatorio, y pueden aumentar el riesgo de contraer cáncer. El agua para uso domestico en Ft Irwin contiene arsénico que varia de no detectado (ND) hasta 34 microgramos por litro (µg/L).
