In July 1988, the water supply to the town and the surrounding area was contaminated when 20 tons of aluminium sulphate was poured into the wrong tank at the nearby Lowermoor Water Treatment Works on Bodmin Moor. An independent inquiry into the incident (the worst of its kind in British history) was started in 2002, and a draft report issued in January 2005, but there is still concern about long-term effects on the health of local people.
