The Madison Water Utility says it will take Well 8 out of service on Tuesday and drain its reservoir.
The well was turned on over the summer and placed in standby mode to ensure an adequate water supply would be available in the event of a major fire or other supply emergency in the area.
Water from the well was never put into the city's water distribution system.
According to the Utility, turning the well on allowed researchers to collect new samples and test the water for tetrachloroethylene (PCE). That is the same chemical contaminating groundwater beneath the nearby Madison Kipp Corporation.
Tests revealed no PCE in Well 8 water.
The Utility says the seasonal use of Well 8 could be critical important next summer, when another well in the area will be offline for a filter installation.
If another year-round well were to have issues at that time, officials say it will be crucial to have Well 8 operational to meet water and fire needs on Madison's east side.
