Concerns are being raised across the province about the safety of drinking water in B.C. schools.

This comes after the discovery of dangerously high lead levels at four Prince Rupert schools. There are questions about whether the contamination could be more widespread and calls are pouring in for province-wide testing.

The NDP is outraged these tests are not routine in all schools, but some districts, like Vancouver, initiate their own.

The opposition says that isn't good enough and it's putting children's health at risk.

"Can he [Health Minister Terry Lake] explain to the house and the people of Prince Rupert just what those routine tests were?", asked NDP leader John Horgan in the B.C. Legislature on Thursday.

"We have had past examples in Kitimat, where this was recognized and that's why the health officer decided to conduct some testing in these schools," said Lake in response.
