Golden State Water Co. has announced that its water supply in Los Osos has been tested and no violations of chromium 6 levels were found.
The company is reporting that the water is safe to drink after the Los Osos Community Services District recently notified its customers that one of its six wells slightly exceeded the state’s allowable level of chromium 6. The chemical, also known as hexavalent chromium, is a human carcinogen.
“I can confirm that Los Osos test results have remained in compliance with the state’s standard for chromium 6,” said Mike Gazda, Golden State’s spokesman. “The water served to Los Osos by Golden State Water is safe to drink and continues to meet all state and federal drinking water quality standards, including California’s new standard for hexavalent chromium (chromium 6).”
Golden State, a private company, serves about half of the Los Osos community, and Los Osos CSD, a public purveyor, provides water to the other half.
Los Osos CSD’s recent testing showed 11 micrograms per liter of chromium 6 in its Third Street well, which has since been shut down. State standards for chromium 6 are 10 micrograms per liter, while federal standards are 100 micrograms per liter.
