Worker covered up polluted schoolwater
Devon County Council has branded the falsification of a school water test result by a private firm as "appalling".
A reading which showed abnormally high levels of iron in the supply at St Peter's Church of England School, in Exeter, was deliberately reduced tenfold by a worker who later resigned, it has emerged.
The employee, who worked for construction and management company Carillion, changed a reading of 1,840 micrograms per litre to just 184, documents released under the Freedom of Information Act (FOI) have revealed.
An investigation was launched which also revealed metal contamination in water supplies at the other five schools run by the firm in the city.
It also found legionella, the bacteria which can cause Legionnaires' disease, in one school.
Carillion said: "Unfortunately, on this occasion, the actions of a single individual failed to meet our high standards."
The council said its evidence indicated no child or member of staff at the schools suffered ill health as a result of the water contamination or the legionella.
