Sunny Mesa WS Has Levels of Hexavalent Chromium

Above the Drinking Water Standard


Pursuant to a California regulation adopted July 1, 2014, the level of a substance called hexavalent chromium should not exceed 0.010 mg/l in drinking water provided by a public water system. This number is known as the maximum contaminant level or MCL.  Senate Bill 385, which became law effective September 4, 2015, allows public water systems, with sources that produce water with a hexavalent chromium concentration above the MCL, time to come into compliance. So long as a public water system complies with the new law (Health & Safety Code, section 116431), it will not be deemed in violation of the MCL.  In addition to other requirements, the new law requires the water system to come into compliance at the earliest feasible date prior to January 1, 2020.

After 24 months of monitoring for hexavalent chromium, and as of the date of this notice, the level of hexavalent chromium in the water provided by our water system is determined to be .012 mg/l which is above the MCL.

Although this is not an emergency, as our customer, 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. We will continue to monitor for the level of hexavalent chromium and provide you with regular notices, at least twice a year.

What should I do?

  • This is not an emergency.  If it had been, you would have been notified immediately. However, some people who drink water containing hexavalent chromium in excess of the MCL over many years may have an increased risk of getting cancer.
  • If you have other health issues or concerns regarding your consumption of this water, you may wish to consult your doctor.

If you wish to avoid drinking the water provided by our water system, you may wish to use alternative water for drinking and cooking.



What happened? What is being done?

We intend to take steps to provide water with hexavalent chromium at or below the MCL. However, to achieve that will take time and money. We have a plan for achieving compliance with the MCL; and on 2019.  We submitted our proposed compliance plan to the State Water Resources Control Board’s Division of Drinking Water for its review and approval. The plan requires us to achieve compliance no later than 2019, which we believe is the earliest feasible date considering the complexity of the plan and the amount of funding required.

The approved compliance plan contains the following actions that the Sunny Mesa Water System will be taking, including a milestone schedule.  This notice will be updated twice each year.

  1. Funding for the project – Apply for Proposition 1 Technical Assistance implemented by the State Water Resources Control Board’s office of Sustainable Water Solutions in 2017.
  2. The District plans to complete the Preliminary Engineering Report by the end of 2016, obtain funding by early 2018, conduct Environmental Studies by the end of 2017, prepare Preliminary Engineering Design early 2018, prepare final Engineering Design by the end of 2018, commence construction bidding period by the end of 2018 and complete recommended facilities by 2019 achieving compliance the same year.
