Controversies & criticism
Camelford water supply contamination In 1988 the public water supply in Camelford in England was accidentally contaminated with aluminium sulphate. Professor Wessely published a paper in 1995 playing down the effects of the pollution and suggesting significant psychological factors were involved. The government formally and unreservedly apologized in 2013, 25 years later, to those whose health was affected by the water supply contamination.
Accusations of poor quality research In 2000 Wessely & fellow researchers were accused of "unsupported conclusions derived from faulty analyses", and responded that "we've been attacked by gremlins" who changed the data on their manuscript.
