If this blue water is safe and there are no other health risks to anyone, why not just test a few hundred pupils and prove it?
The safety of two Coatbridge schools – Buchanan High and St Ambrose – on the same site has become a national political controversy over the last few months.
The newbuild is located on land which had previously been used for burying domestic and industrial waste. Ahead of construction, remediation work was carried out and the grounds were certified as being safe.
However, concerns were flagged up that the drinking water on the campus had turned blue. It has since been reported that four serving and retired teachers at Buchanan High have bladder cancer.
A parent has also demanded answers after her child, a pupil at Buchanan, lost his sight."
