Water Quality for Central Marina & Ord Community

Water quality throughout the Central Marina and Ord communities is diligently monitored by the Marina Coast Water District. Before water reaches your tap, water samples are collected and tested in state certified laboratories. Samples are collected from a combination of source wells, chlorination treatment sites, storage tanks, distribution system, and from point-of-use locations.

Our regularly scheduled water sampling program along with our prudent operations and maintenance team, ensures that your water meets all State and Federal drinking water standards.
The District samples for coliform bacteria (Total and E.coli) in the distribution system on a weekly basis as a part of our routine sampling program. Sampling for coliform bacteria may help indicate the presence of disease-causing organisms therefore allowing the District to take proactive measures to ensure your water is safe to drink. Samples are collected from state approved distribution system locations, which consist of taking five samples from Central Marina and five samples from the Ord community; a different set of five is analyzed each week for both service areas. In total, there are forty different distribution sample locations that the Operations staff sample each month. 

The District also collects and analyses regulatory water samples which monitor compliance for over 200 constituents in the drinking water; many of these constituents are naturally occurring substances. The water supply samples are tested for general minerals such as calcium, magnesium, hardness; inorganic chemicals such as arsenic, chromium and other metals; organic chemicals such as solvents, pesticides and herbicides; radioactivity including radon; asbestos and other chemicals that are still not regulated and have no state or federal standards. The distribution system is also tested for disinfection by-products such as total trihalomethanes (TTHM) and haloacetic acids (HAAs5). Every three years, lead and copper samples are collected from faucets located inside homes throughout the Central Marina and Ord Community to check for elevated levels of lead or copper, which can come from leaching of pipe materials used in water lines. 

In addition to regulatory testing required by the state, the District voluntarily samples for a wide array of constituents that monitor the general/physical and chemical parameters for both Central Marina and the Ord Community. Water samples are tested for color, odor, turbidity, temperature, pH, conductivity, free chlorine residual, and sulfides.

It is important that we provide you with accurate and easy to understand water quality information. Please review the monthly summaries as listed at the bottom of the page.

Monitoring Data for Unregulated Contaminants

The District also samples for a series of unregulated contaminants which are those that do not yet have drinking water standards set by the EPA. The purpose of monitoring unregulated contaminants is to help the EPA decide whether the contaminants should have a standard set for monitoring. Every 5 years, the EPA issues a new list of unregulated contaminants that need to be monitored by public water systems; these lists are denoted by UCMR, or Unregulated Contaminant Monitoring Rule, and the version that is currently being used. The District conducted sampling for the UCMR4 reporting, which requires monitoring between 2018 and 2020. To view the results from the UCMR4 study, please click here.

As our customer, you have a right to know what your water contains and where it comes from. If you are interested in examining the water quality results, please review the latest version of the annual Consumer Confidence Report (CCR) here; this report is also available in Korean, Spanish, Tagalog, and Vietnamese. Should you have any questions regarding the water quality, please contact Derek Cray, Operations and Maintenance Manager, at (831) 384-6131 or via email at dcray@mcwd.org.
