Oak Hills hexavalent chromium warning (January 8, 2016)


County Service Area 70J, Oak Hills has levels of Hexavalent Chromium above the Drinking Water Standard

Our water system recently violated a drinking water standard. Although this is not an emergency, as our customers, you have a right to know what you should do, what happened, and what we are doing to correct this situation.

We routinely monitor for the presence of drinking water contaminants. Water sampled on October 6, 2015 showed Hexavalent Chromium levels 18-23 micrograms/liter (ug/L). Compliance for Hexavalent Chromium is based on the Running Annual Average (RAA) of the results. The RAA for the 4th quarter 2015 was 18ug/L. This is above the State Water Resources Control Board, Division of Drinking Water standard for maximum contaminant level (MCL) of 1 Oug/L.

What should I do?

  • You do not need to use an alternative water supply (e.g., bottled water}.
  • This is not an emergency. If it had been, you would have been notified immediately. However, some people who drink water containing Chromium in excess of the MCL over many years may have an increased risk of getting cancer.
  • If you have other health issues concerning the consumption of this water, you may wish to consult your doctor.

What happened? What is being done?

The Department is currently looking into treatment methods and alternative sources. We anticipate resolving the problem in a timely matter.

For more information, please contact Steve Samaras at 760-955-9885 or the Special Districts Department, Water and Sanitation Division, 12402 Industrial Blvd., Suite D-6, Victorville, CA 92393.

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 apartments, nursing homes, schools, and businesses).
