A copy of a letter from Hugo Kristinsson which was sent to Helen Beaumont, Manager of the Natural Environment and Heritage Unit at the Christchurch City Council, on 17 June 2014. The letter was sent on behalf of Empowered Christchurch. It is about legislation which, according to Kristinsson, determines land below the mean high water spring to be public land. Kristinsson is concerned that this legislation will cause 'hundred or even thousands' of people to lose their assets. He urges the Council to 'have the land surveyed and to redefine the CMA [Crown Minerals Act] before land claims are settled'.

A PDF copy of a fact sheet about hydraulic fracturing (fracking) in the South Island created by Anglican Advocacy in 2011. The fact sheet contains information about the possible impacts of fracking on water and the risk of earthquakes.

Study region: Christchurch, New Zealand. Study focus: Low-lying coastal cities worldwide are vulnerable to shallow groundwater salinization caused by saltwater intrusion and anthropogenic activities. Shallow groundwater salinization can have cascading negative impacts on municipal assets, but this is rarely considered compared to impacts of salinization on water supply. Here, shallow groundwater salinity was sampled at high spatial resolution (1.3 piezometer/km²), then mapped and spatially interpolated. This was possible due to a uniquely extensive set of shallow piezometers installed in response to the 2010–11 Canterbury Earthquake Sequence to assess liquefaction risk. The municipal assets located within the brackish groundwater areas were highlighted. New hydrological insights for the region: Brackish groundwater areas were centred on a spit of coastal sand dunes and inside the meander of a tidal river with poorly drained soils. The municipal assets located within these areas include: (i) wastewater and stormwater pipes constructed from steel-reinforced concrete, which, if damaged, are vulnerable to premature failure when exposed to chloride underwater, and (ii) 41 parks and reserves totalling 236 ha, within which salt-intolerant groundwater-dependent species are at risk. This research highlights the importance of determining areas of saline shallow groundwater in low-lying coastal urban settings and the co-located municipal assets to allow the prioritisation of sites for future monitoring and management.
