Jinko Solar Holding Co., a China-based solar module manufacturer, has temporarily halted production at a factory in the Zheijiang province of China after spilling factory waste into a nearby brook.
The Wall Street Journal reports that the contamination incident set off violent demonstrations by more than 500 protestors at the factory.
Jinko said that a solid-waste buildup containing fluoride ran into the brook following torrential rains. Fluoride levels climbed above normal, according to measurements taken by the local environmental protection bureau.
Jinko added that it takes responsibility for the spill and has already implemented additional waste-management measures.
