Tests revealed no traces of lead in water fountains at Argenta-Oreana schools after the district undertook replacements and repairs, the district said in a statement Friday.
State law requires all schools with students in fifth grade and under built before 1987 be tested for lead. Schools that have lead of more than 5 parts per billion must notify parents.
In October, five of the district's water fountains — two at the elementary school, one at the middle school and one at the high school — tested positive. The district subsequently replaced four of the older models, and installed an inline lead water filter in all of them.
Once the results came back with no trace of lead, all the fountains were reopened for staff and student use, the district said.
