Continuous air-quality testing is being done due to a hydrocarbon leak near the Moruga Secondary School.

Heritage Petroleum says the source of the leak has been clamped and the site restored.

However, due to reports of an odour being picked up at the school, several measures were taken, out of caution.

The company says testing has shown air quality to be within acceptable levels, with port a cool fans installed as well to improve circulation in specific areas of the school.
