A stronger disinfectant will be temporarily used in the Lopez Lake drinking water distribution system, the San Luis Obispo County Department of Public Works announced Thursday.

Between Thursday and Nov. 23, the department will apply a free chlorine disinfectant rather than the blended chlorine treatment that is typically used. Free chlorine is a stronger disinfectant than blended chlorine and is part of an annual switchover of disinfectants to help rid the water of potentially harmful bacteria, said Craig Kesler, chief plant operator.

Because the county provides water to the cities of Arroyo Grande, Pismo Beach and Grover Beach, Oceano and Avila Beach community services districts and Port San Luis, those water systems may also convert their treatment processes to free chlorine.

Anyone with questions and concerns about their drinking water should contact their local water supplier.
