A third round of water testing around Ohakea Airforce Base has found ponds and streams too contaminated for swimming, stock water or irrigating crops.
However neighbouring landowner Andy Russell is not too alarmed, because little or none of the water is used for those purposes. He's guessing a lot of the samples were taken from drains surrounding the base tarmac.
"There's no business interruption as far as farming goes."
The tests have been paid for by the New Zealand Defence Force (NZDF), because the contamination is from one of the ingredients of the foams used to fight fires in flammable liquids. The base uses such foams, both for real fires and in training.
But its spokespeople say it has been conducting training elsewhere since early 2016, and since 2002 the foams it has used contain only tiny amounts of the contaminant - PFAS (per- and poly-fluoroalkyl substances).
