LOWELL | After three weeks of bottled water use and a bulk water supply for the cafeteria, the water is back on at Lake Prairie Elementary School.
Principal Lisa Patton informed parents and teachers Monday that the school's well water will be back online Tuesday.
Bottled water will no longer provided, although parents may send their children with bottled water if they wish.
The problem of dark, murky water resurfaced Feb. 11, and school officials acted quickly to turn off water fountains and supply bottled water.
In a letter to parents Monday, Nathan Kleefisch, Tri-Creek Schools assistant superintendent, said test results and visual monitoring during the past few days proved the water to be safe and complying with required water standards.
Previously, professionals consulted on the problem said the black water periodically experienced is the result of a reduction in chlorine during the water treatment process.
Shortly after the dark water was discovered in February and the situation evaluated, the decision was made to install four 120-gallon water storage tanks where chlorine will be used in treatment.
Black water incidents at the school occurred last October and in February and August 2012.
Lake Prairie is west of Lowell, and there are no municipal utility lines in place to deliver it there.
In previous talks, bringing Lowell water to the school was considered, but not seen as a good option due to the cost to construct water system lines to the school. The cost would be borne by the school system and deemed too expensive.
