Northern Saratoga Springs, Utah, residents, were told to boil their water for a few days, in mid-May, after an outbreak of Campylobacter had been detected. The epidemiologic investigation implicated drinking water from the municipal water supply; a problem was detected with one of the wells. The affected subdivisions were Harvest Hills, Aspen Hills, Sunrise Meadows, Dalmore Meadows, Summer Village, Sunset Haven, Sierra Estates, Riverbend, The Cove at the Jordan River, The Gables, Sergeant Court, Daybreak at Harvest Hills and Hillcrest condominiums. Westlake High School and Harvest Hills Elementary School and Lakeview Academy were also in the affected area. Outbreak related cases were reported into early June. Health officials suspected that persons who connected to the potable water lines for the purpose of providing irrigation in the fall, after the assigned irrigation water lines were shut down, contaminated the potable water system.
