Average estimated groundwater volume, by region, 2010-2014
New Zealand's Environment Reporting Series: The Ministry for the Environment and Statistics New Zealand
Groundwater is the water stored beneath Earth’s surface in aquifers (layers of water-bearing rock or sand). It is used for human and stock drinking water, irrigation, and industry, and also has a role in sustaining some rivers, lakes, and wetlands, especially during low-flow periods. The health of surface-water ecosystems also depends on groundwater.
Estimated average groundwater volumes by 16 regional councils * region = Regional Council * bil_cubicm = Average estimated groundwater volume in billion cubic metres
