Foam used to fight fires at three regional airports has been found to contain a pollutant, and an order has been made to stop its use.
The Environmental Protection Authority confirmed on Monday that foam used by two fire trucks at Gisborne, Hawke's Bay and Palmerston North airports contains PFOS (perfluorooctane sulfonic acid), which is harmful in the environment and may affect human health.
As a result, the EPA has served a compliance order on Task Protection Services Ltd, as part of its inquiry into fire-fighting foams.
The company owns and controls fire trucks and fire-fighting foams at Palmerston North, Gisborne, and Hawke's Bay airports.
Lab tests are still being carried out, EPA chief executive Allan Freeth says, but the compliance order issued means Task Protection Services Ltd must stop immediately using the foam for training or testing purposes, and entirely by May 4.
