An anonymous reader writes "Intel had to shut down part of its Irish plant for a while because of the extreme cold and the fact the local council polluted the water supply with fertilizer. Apparently it got down to -12 degrees C at the Intel plant in Leixlip, County Kildare. But to make matters worse, the local council ran out of rock salt to grit the roads and opted for fertilizer instead. There were fears that ammonia and nitrates in the fertilizer might have contaminated the local water supply. The problem for the chipmaker is that it needs extremely pure water for its manufacturing processes."
