Officials in a North Carolina county say slightly elevated levels of lead have been found in the water at two elementary schools.

School officials in Harnett County told local media that bottled water is being provided to students at Erwin Elementary and Benhaven Elementary.

Officials said the slightly elevated lead levels were found in several places in the buildings but not in the kitchens.

Erwin Elementary was built in 1926 and upgraded in 1948. Benhaven was built in 1924 and upgraded in 1936 and 1948.

Officials said since they learned of the test results, they've flushed the water system. They've also removed some water fountains and sinks and replaced them with water dispensers and hand-washing stations.

Water is being brought in for the ice machines and cafeterias.
