Some rural Marion County residents can expect a boil order to continue through the weekend. Officials at Marion County Rural Water tell KNIA/KRLS News they must test the water for contaminants. The water main break lowered water pressure, increasing the chance that contaminants have entered the water stream. Officials say if all goes well, the advisory will be lifted tomorrow or Monday. KNIA/KRLS will let listeners know as soon as the boil order is lifted.
