Christchurch shallow groundwater quality survey

The dataset contains shallow groundwater quality records (specific conductance at 25 °C, temperature, pH, and dissolved oxygen) from 99 piezometers across Christchurch, New Zealand, following the pumping of approximately three bore volumes in the spring of 2020. Out of the 99 piezometers, 27 piezometers were sampled for chloride concentration and alkalinity as calcium carbonate. The piezometers used are part of the extensive shallow groundwater piezometer network owned by Christchurch City Council.
