To ensure that your water meets state safety standards, Golden State Water Company is required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not your drinking water meets health standards. During the calendar year 2020, we did not monitor for 1,2,3- Trichloropropane from Del Monte Well 2, Dreher Well 1, Indian Hill Well 3, Harrison Well 2, College Well 2, and Indian Hill Well 4 and therefore, cannot be sure of the quality of your drinking water during that time. However, 2021 and 2022 sampling results revealed no detection of 1,2,3-Trichloropropane, which is historically consistent with Del Monte Well 2, Dreher Well 1, Indian Hill Well 3, Harrison Well 2, College Well 2, and Indian Hill Well 4. We believe there is no health risk associated with drinking water produced from these wells and that the water meets state drinking water standards. Be reassured that Golden State Water Company will continue to conduct water quality tests essential to delivering reliable, quality water.

Golden State Water Company did not monitor as required for drinking water standards during the past year and, therefore, was in violation of state regulations. Even though this failure was not an emergency, as our customers, you have a right to know what you should do, what happened, and what we did to correct this situation.

What should I do?

  • Your water remains safe to drink and use. There is nothing you need to do at this time.
  • The table below lists the contaminant we did not properly test for during the past year, how many samples we are required to take and how often, how many samples we took, when samples should have been taken, and the date on which follow-up samples were taken.

  • If you have health issues concerning the consumption of this water, you may wish to consult your doctor.

What happened? What is being done?

As stated above, in 2020, we did not monitor as required for drinking water standards for 1,2,3-Trichloropropane. As corrective action, we updated our monitoring system to ensure annual sampling. Also, training was provided to Water Quality staff on monitoring schedule and compliance requirements. We have since taken the required samples, as described in the last column of the table above. The samples showed we are meeting drinking water standards.

For more information, please contact George Zakhari, Water Quality Engineer at 1.800.999.4033.
