Four Walker County Schools had some faucets with detectable levels of lead in the water after the school system had all four tested through an optional Georgia program, according to a notice from the district.
After the district posted the information on social media, some parents expressed concerns they were not alerted earlier to the test results.
Fairyland Elementary, Chattanooga Valley Elementary and Naomi Elementary were tested in November. Stone Creek Elementary was tested in April.
The notice, posted Tuesday, said the four were chosen for testing because portions of the buildings were built before 1980. The system has 15 schools.
Though health officials say there is no safe level for lead consumption, the American Academy of Pediatrics recommends school water fountains not exceed 1 part of lead per billion parts of water. For water systems, the Environmental Protection Agency’s lead action level is 15 parts of lead per billion parts of water.
