Vast Quantities of Nitrates Are Stored in Rocks Above Drinking Water Resources

PALMERSTON NORTH

A paper published by researchers at the British Geological Survey has found vast quantities of nitrate across the globe stored in rocks above drinking water resources. The authors estimated up to 180 million tonnes of nitrates are stored in rocks worldwide, perhaps twice the amount stored in soils. Massey University ecology and environmental science senior lecturer Mike Joy said the impacts were already being seen in New Zealand.
