Entregando agua limpia y segura a todo el condado de San Diego

La prioridad principal de la Water Authority es proporcionar agua segura a sus 24 agencias miembros minoristas y a sus clientes. El monitoreo regular de la calidad del agua y el uso de equipo de inspección en línea garantizan que la Water Authority entrega agua segura de la más alta calidad a sus agencias miembros las 24 horas del día, los siete días de la semana.

Instalaciones

Instalaciones de tratamiento regionales

El agua potable que provee la Water Authority a sus agencias miembros proviene de tres fuentes principales: la Planta Desalinizadora Claude “Bud” Lewis Carlsbad, la Planta de Tratamiento de Agua Robert A. Skinner en el condado de Riverside — que posee y opera el Distrito Metropolitano del Sur de California—, y la Planta de Tratamiento de Agua de Twin Oaks Valley al norte de San Marcos. Ya sea que el agua tratada la procese el MWD, la Water Authority, o una agencia local, toda el agua tratada del condado de San Diego cumple o supera los estándares estatales y federales más rigurosos de calidad del agua.

Planta Desalinizadora Claude “Bud” Lewis Carlsbad

The Carlsbad Desalination Plant is the nation’s largest, most environmentally friends and most technologically advanced seawater desalination plant. It is the result of a public-private partnership between the Water Authority and Poseidon Water, and it treats up to 50 million gallons per day.

Fluoración

California Fluoridation Regulations

Since the 1990s, state law has required water suppliers with 10,000 or more service connections or customers to fluoridate their water supply. The California Fluoridation Regulations adopted by the California Department of Health Services were added to the California Code of Regulations in April 1998.

Naturally occurring fluoride levels range from 0.1 to 0.4 parts per million, and water in San Diego County averages 0.23 parts per million. To reach the optimal range for dental health, fluoride must be added to reach 0.7 to 0.8 parts per million.

Agencies relying on the Water Authority for all of their treated water will receive fully optimized fluoride concentrations. Retail water agencies that blend Water Authority supplies with non-fluoridated supplies have lower fluoride levels. Systems that receive no treated water from the Water Authority have only naturally occurring levels of fluoride.

Flouridation Resources

San Diego County consumers can learn more about fluoride in their water by visiting the California State Department of Health or by contacting their local retail water provider.

MWD maintains a Water Quality Information Hotline at (800) 354-4420. Consumers with questions about whether they should adjust dental health practices should consult their dentist.

Regular Lead Testing

The Water Authority regularly tests for the presence of lead and other potential contaminants in its supply sources and in the water it delivers to member agencies as part of its overall water quality monitoring program, using a range of techniques from real-time monitoring to laboratory testing.

Tests show no detectable levels of lead in any potable water from any treatment plant that serves the Water Authority.

The water source for the Carlsbad Desalination Plant is seawater from Agua Hedionda Lagoon, while the water source for the Skinner and Twin Oaks Valley treatment plants are from the State Water Project in Northern California and the Colorado River. Each of these sources is tested for lead annually in accordance with regulations from the U. S. Environmental Protection Agency and the State Water Resources Control Board, Division of Drinking Water. Local reservoirs are tested annually in accordance with state and federal water quality rules.

School Testing Regulations

Public concern over lead in other states’ drinking water supplies prompted the California Division of Drinking Water to enact a new requirement for the testing of water for lead in schools that took effect in 2018.

As of July 1, 2019, the Division of Drinking Water, in collaboration with the California Department of Education, has completed the initiative to test for lead in drinking water at all public K-12 schools.

Lead Resources

When lead is detected by customers, the most common cause is internal corrosion of plumbing systems and service lines that are the responsibility of the property owner. Consumers concerned about lead in drinking water can learn more on the EPA’s website or by calling the Safe Drinking Water Hotline at 1-800-426-4791. Bilingual service is available on the hotline.
