Conversion of Drinking Water Disinfectant to Free Chlorine in the Five-Cities Area

FOR IMMEDIATE RELEASE

Date: November 7, 2024

Conversion of Drinking Water Disinfectant to Free Chlorine in the Five-Cities Area May Temporarily Affect the Water's Taste and Smell.

FIVE-CITIES - Some residents may notice a slight change to the taste or smell of their water as the San Luis Obispo Department of Public Works changes the disinfectant in the Lopez Project distribution system November 13 through December 2, 2024. During this period, the disinfectant will be switched to free chlorine. This change will impact the water supply for the cities of Arroyo Grande, Pismo Beach, Grover Beach, Oceano, Avila Beach, and Port San Luis, as these areas may also be converted to free chlorine.

The County uses a blended chlorine treatment for disinfection; however, free chlorine is a more effective disinfectant. Switching to free chlorine each year helps maintain water mains free of potentially harmful bacteria, aligning with best management practices in the water industry.

Individuals may have varying sensitivity to the taste or smell of chlorine in water. While some may not notice any change, others might detect a taste or odor similar to that of a swimming pool. To reduce or remove free chlorine, you can boil the water, use a carbon filter, or let the water sit uncovered overnight to allow the chlorine to dissipate.

Chlorination is the most widely used method for disinfecting drinking water. For most consumers, no special precautions are necessary, as the water meets Federal and State drinking water standards. If you have any questions or concerns about your drinking water, feel free to contact your local water provider.
