There are growing concerns over contaminated well water at Lebanon Elementary School after small traces of arsenic were discovered.
The drinking fountains have been disconnected for nearly a month, and the school has been using bottled water to give to students.
School officials said they were waiting for test results to come back before they decide when the well can reopen.
Arsenic is odorless and tasteless and can naturally occur in the environment as well as being used in pesticides.
The inorganic type of arsenic can be toxic.
"With kids that young, a small amount could do more damage than to an adult I would think," Alan Morrison, of Lebanon said. "I have a well. Maybe I should have mine checked. I don't know."
The district said it checks its wells four times a year for clarity, and is tested every three years for organic compounds like arsenic.
