Harmless Odor and Taste in water

The City of Morro Bay receives State Water from the Central Coast Water Authority (CCWA), and typically once a year this water has harmless algae compounds called Geosmin. Geosmin is caused by high temperatures, which creates ideal conditions for blue-green algae blooms in the Sacramento-San Joaquin Delta, affecting State Water Project customers, including the City.  While Geosmin produces an earth smell and taste in drinking water, it is not harmful at levels present in drinking water. These compounds do not affect the water quality; City water continues to meet all Federal and State drinking water standards.

The City water supply remains safe for consumption and use. Customers may have various levels of sensitivity to the taste and odor due to the harmless algae. Drinking water carbon filter systems, i.e., Brita filter, or chilling the water will help eliminate the taste and odor issues. Also, The City is making operational changes where possible to reduce the odor and taste impacts of Geosmin.
