NBRID is a community surface water system sourced from Putah Creek. Raw water from the creek is treated and disinfected at the water treatment plant, and then pumped into the distribution system where it flows to your tap.
There can be many sources of contamination of water systems. The most common sources of contaminants include:
EPA and the State regulates many contaminants that pose known human health risks. Testing of both raw source water and treated drinking water determines if any contaminants are present and to what extent the water system must treat water to ensure those contaminants are removed after treatment.
Different water filters have different functions. Some can make your water taste better, while others can remove harmful chemicals or germs. Visit CDC’s filter page to learn more about home water filters.
Every community water supplier must provide an annual Consumer Confidence Report (CCR) to its customers.. The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water. Six (6) years of CCRs for your system are posted here; most CCR’s for prior years are available upon request – [email protected]
Frequency of drinking water testing depends on the number of people served, the type of water source, and types of contaminants. You can find out about levels of regulated contaminants in your treated water for the previous calendar year in your annual consumer confidence report (CCR).
If you are concerned about contaminants in the NBRID water system, contact your state drinking water certification officer to obtain a list of certified labs that can help you determine what specific tests may be of interest. Depending on how many contaminants you wish to test for, the cost of a water test can range from $15 to hundreds of dollars. Visit EPA’s Safe Drinking Water Information website if you have questions external icon on testing methods.
A change in your water’s taste, color, or smell is not necessarily a health concern. However, sometimes a change can be a sign of problems. If you notice a change in your water, call the NBRID main office at 707-259-8600 (M-F 8 am – 5pm), or the operations team at 916-584-1893, at any time.
If you want to test your water yourself, the County Environmental Health department (707-253-4417) or State Division of Drinking Water (916-341-5455) may be able to assist in explaining any tests that you need for various contaminants. If your local health department is not able to help, contact a state certified laboratory to perform the test.
