We have clean water, fresh air and healthy soils. Well-functioning and diverse ecosystems make up an environment that can support our needs. Resources are used efficiently. There is minimal waste and pollution.
Good air, water and soil quality, and reducing waste are all essential to maintaining a healthy environment and ensuring the sustainability of resources. Water-based recreational activities are part of an outdoor-focused way of life and it is essential that the water is of a high quality. Protecting land through open space covenants also helps maintain ecosystem diversity, along with natural and cultural heritage. Primary land uses such as agriculture, dairying and cropping are key contributors to an economy but they can have a negative influence on the environment.
Healthy Environment is made up of 16 indicators that were selected to measure progress towards the healthy environment outcome definition (shown above). Please see below for the raw data available over the 2001 to 2010 study period for each of the healthy environment indicators.
As with the Environmental well-being GPI (which is the same as the Healthy Environment GPI), the available indicator data that forms the healthy environment outcome area was used to calculate individual index values for each indicator for each year over the 2001 to 2010 study period. The graph below shows the average of these individual index values, and represents the healthy environment GPI for the Wellington region from 2001 to 2010.
A GPI is an attempt to measure whether a nation’s or a region's growth, increased production of goods, and expanding services have actually resulted in the improvement of the well-being of the people in the region.

Nitrate is a commonly measured indicator of groundwater quality. Compliance with the national standard should ensure that it is safe for the water to be used for human (and stock) consumption. Elevated nitrate concentrations may indicate a health risk as well as a risk of adverse impacts on the water quality in rivers and lakes, and in freshwater ecosystems. Greater Wellington Regional Council uses a threshold of less than 3mg/L of nitrate (measured as nitrate nitrogen) as their indicator of good water quality.
The number of groundwater monitoring sites that have median nitrate concentrations in the <0.002-3.0mg/l range expressed as a function of the total number of groundwater sites monitored
