Newport Beach Water Quality Report


Water Production operates, maintains, and disinfects the City of Newport Beach’s water supply. The division operates two well sites that produce groundwater from the Orange County Basin as well as three water reservoirs to receive, store and distribute the City’s water. Other water facilities that assist in the distribution and treatment process include five water pump stations, five Metropolitan Water District interconnections, and 42 water pressure regulating stations. Water Production also manages SCADA (Supervisory Control and Data Acquisition) which monitors and controls the pumps in the City’s water wastewater and gas systems.

Orange County’s water supplies are a blend of groundwater managed by OCWD and water imported from Northern California and the Colorado River by the Municipal Water District of Orange County (MWDOC) via the MWDSC. Groundwater comes from a natural underground aquifer that is replenished with water from the Santa Ana River, local rainfall and imported water. The groundwater basin is 350 square miles and lies beneath north and central Orange County from Irvine to the Los Angeles County border and from Yorba Linda to the Pacific Ocean. More than 20 cities and retail water districts draw from the basin to provide water to homes and businesses.


The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the
the surface of the land or through the layers of the ground it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animal and human activity.

Contaminants that may be present in source water include:

Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production or mining activities.

Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm runoff, industrial or domestic wastewater discharges, oil and gas production, mining and farming.

Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gasoline stations, urban stormwater runoff, agricultural application, and septic systems


Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised people, such as those with cancer who are undergoing chemotherapy, persons who have had organ transplants, people with HIV/AIDS or other immune system disorders, some elderly persons and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers.

The USEPA and the federal Centers for Disease Control guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from USEPA’s Safe Drinking Water.

When Captain Samuel S. Dunnells successfully steered his 105-ton river steamer Vaquero through upper Newport Bay in 1870, James and Robert McFadden rushed from Northern California by stagecoach to mark the inaugural voyage.

Dunnell’s’ trip cast new light on the bay, which many had said was too treacherous for travel. But the principal landowners in the area – the McFadden brothers and James Irvine – thought they had something after Dunnells’ trip. A “new port,” they mused, and the name stuck, according to the Newport Beach Historical Society.

More than 100 years later, Newport Beach’s harbor is crowded with pleasure, fishing and tour boats, and its streets are busy with shoppers browsing at Fashion Island mall, tourists enjoying Balboa bars on Balboa Island and surfers tackling The Wedge or other hot spots along the city’s 6.2 miles of beaches.

Newport wasn’t always such a desirable place. In the mid-1800s, the state of California sold parts of Harbor, Balboa, and Lido islands for $1 an acre as “swamp and overflow land,” according to the Newport Beach Historical Society.

The McFaddens saw something else. In 1888, they decided their shipping business would be more successful if they moved it from the inner shores of the bay to the oceanfront, where they could build a wharf. McFadden Wharf soon became the largest business in newly created Orange County, according to the historical society.

In August 1906, residents in the booming bay town voted to incorporate. The vote was 42-12 to become the city of Newport Beach. Back then, bayfront houses sold for as little as $500. Today, the median price of homes in Newport Beach is approximately $545,000.

Residents identify closely with their “villages” – including Corona del Mar, West Newport and the Harbor, Lido and Balboa islands – rather than Newport Beach itself. Homes are separated from busy commercial areas such as Lido Village, Mariner’s Mile and Newport Center.

One hundred years after the McFaddens built what is now Newport Pier, the city still revels in its ocean roots. Back then, only a few dozen summer cottages could be rented, and a few dozen people called Newport home.
