MEMPHIS (AP) — Rhodes College is removing four drinking fountains and replacing two others after testing found elevated levels of lead.

Rhodes tested all 110 fountains on campus, according to a campus message from Kyle Webb, vice president for finance and business affairs, the Daily Memphian reports. The six fountains that had unsafe lead levels have been disabled.

The water on campus is safe to drink, and there are no ongoing concerns, according to Webb.

The Memphis college is offering blood testing in its student health center for concerned students.
