(Francisco Kjolseth | The Salt Lake Tribune) Elliott Purser, center, and Cody Hook with Sandy City load up cases of water into the trunk of a resident at the Sandy Operations Center at 9150 South, 150 East on Sunday, Feb. 17, 2019. The no drink order now applies only to homes and businesses between 1700 East and 2000 East and 10600 South and 11400 South, the city announced Sunday. The city says the problem started about Feb. 6, when a fluoride pump malfunctioned because of a power outage. It flooded the water system with fluoride and that also led to high levels of lead and copper, enough that it made some people sick.
