TEACHERS at two schools where “blue water” came out of taps could resume their strike after the summer holidays if new contamination tests are not carried out.

Teachers at St Ambrose high school kicked off their strike today, joining colleagues from Buchanan high who have been on strike since last week.

Concerns have been raised at the schools, which share a joint site in Coatbridge, North Lanarkshire, after four current and former teachers developed bladder cancer.
