An ongoing investigation into recent E. coli cases in Lehi led to the detection of E. coli O157 in samples collected from pressurized irrigation (PI) water sources in Lehi. Samples were taken from a PI reservoir and nine exposure sites on Monday, August 14. E. coli O157 was found in the sediment of the tested reservoir and at five of the exposure sites.
The investigation linked the source of the outbreak to using pressurized irrigation for drinking and recreation, such as running through sprinklers or playing on slip-n-slides. Currently, the Utah County Health Department has reported a total of 12 cases of E. coli. Pressurized irrigation water, unlike culinary water, is not treated, leaving it susceptible to contamination by harmful bacteria, including E. coli. The effects of E. coli can be severe, leading to a range of health issues. Pressurized irrigation water is not connected to the city culinary drinking water system. Using culinary water to water the lawn should not be used as an alternative water source.
