Environmental reporting
To find out how successful we are in our efforts to manage the environment in a sustainable way, we prepare annual reports and summary report cards on air quality, bathing water quality, freshwater quality, surface water hydrology, groundwater and coastal monitoring. These reports and more detailed technical reports contribute to Greater Wellington's five-yearly State of the Environment Report, known as Measuring Up.
Every month we produce hydrological summaries of recent trends in rainfall, river flows and groundwater levels.
