San Luis Obispo County lifted the boil-water order for all remaining areas on Saturday afternoon, following a water-contamination alert that lasted four days. According to an alert from the county, the boil-water order was lifted shortly after noon, allowing residents in Pismo Beach and Avila Beach to resume normal water use, after the State Division of Drinking Water gave the all-clear. … The county said it was working with state officials to investigate the cause of a single positive E. coli test result that spurred the boil order. The investigation is expected to take 30 days. Director of Public Works John Diodati said the drinking water is safe and will be monitored and tested as the county investigates the cause.
