Abstract
In the summer of 2014-15, short-term groundwater related investigations were undertaken in support of the Waiora He Rautaki Whakapaipai project (Healthy Rivers - Plan for Change). This project will establish limits and targets for nutrients (as well as sediment and E. coli) in waters of the Waikato and Waipa catchments. A focus on time lags and losses inherent in nitrogen transport in groundwater was part of the work undertaken and is described here. Brief reporting of radon surveys to characterise groundwater input to streams is also reported.
