In consultation with the community, Otago Regional Council (ORC) developed a plan for managing rural water quality in our region. The Water Plan gives landholders the flexibility to manage their land activities in such a way that the water quality of our freshwater resources such as rivers, lakes and aquifers continues to be of a high standard both now and in the future.
On 30 June 2016 the ORC wrote to landholders in the Kakanui community, south of Oamaru, requesting their participation in a groundwater and surface water science study to measure the nitrogen leaching rate from their land. This is in response to the Kakanui community requesting ORC to review the nitrogen leaching threshold over the Kakanui-Kauru Alluvial Aquifer.
A computer model called OVERSEERĀ® will be used to collect data for this study between 1 July 2016 and 30 June 2017. OVERSEERĀ® will be used to calculate losses of nitrogen through the ground, known as the nitrogen leaching rate. Knowing the nitrogen leaching rate helps inform our science work in relation to potential impact on water quality from land use activities.
Certified Nutrient Management Advisors (CNMA) will work alongside landowners for the duration of the study and will prepare a report on the findings. They will provide the report to landholders and then relevant information for the science study to ORC. A list of CNMAs working in Otago can be found at: http://www.nmacertification.org.nz.
The results will:
This science study is just one step in the process of the ORC and landowners working together to ensure the Water Plan is right for their community, particularly in an environmental, social, and economic context.
