The Defence Force has changed tack, just three days after saying it had stopped using potential damaging firefighting foam for training at all its bases in 2016.
The foam, called Aqueous Fire Fighting Foam (AFFF) or fluorine foam, no longer contains banned chemicals that are extremely longlasting and have been linked to damage to human health and the environment.
But it does contain related compounds called PFASs that research indicates are harmful.
Last week Horizons Regional Council, ordered the Defence Force to stop discharging stormwater with the firefighting foam in it.
The Defence Force responded with a statement saying saying it stopped using the firefighting foams at Ōhakea and at "all of its bases in 2016".
But NZDF has backtracked.
It told RNZ. our previous response that we stopped training with foams 'at all of our bases' referred to 'air bases', and apologises that this was not clear in the initial response.
