CAIRO, IL (KFVS) - Water experts say the water in Cairo is not harmful for your health. However, residents are still concerned.
John Lawrence says he's been boiling the minerals out of his tap water for about two weeks. He says if he doesn't it will damage his appliances.
"Otherwise the sediment is going to clog up my coffee pot," Lawrence said.
Experts say the buildup is caused by calcium and other minerals in well water.
American Water Company officials say they switched service from river water to well water on August 21. They say the well water service is only temporary. Officials say they installed the well so customers would still have water service during maintenance to the old system.
Water quality expert Rachel Bretz says the water is safe to drink; the minerals in well water are not harmful.
However, Lawrence is concerned about extra costs.
"This water heater should last ten years but I'm extremely certain that's it's only going to be good for eight years because of the sediment," Lawrence said.
One plumber says hard water with an extreme amount of calcium could cause water heaters to be less-efficient, but only if hard water is being used for a long period of time.
American Water Company officials say they plan to have the other system up and running within the next three weeks, meaning they will no longer provide well water service.
