Description: Location of springs information as recorded in Environment Canterbury's Wells database.
Location accuracy is given by the QAR_CODE field:
1 = 1-2 metres
2 = 2-15 metres
3 = 10-50 metres
4 = 50-300 metres
Description: Provisional protection zones for Community and Group drinking water sources have been delineated in accordance with Schedule 1 of the proposed Canterbury Land and Water Regional Plan and are based on the best available information as at May 2015. Environment Canterbury has reviewed information on the location of Community and Group drinking water sources in association with Water Suppliers, Territorial Authorities and Community and Public Health
Description: Shows areas where the average depth beneath surface level to the top of the water table is greater than 6 metres. Depth was calculated by measuring the distance to the highest water level at wells that as at 2003 had greater than 12 recorded observations. Areas where depth to ground water was greater than 6 metres were then interpolated from these measurements. Areas not included are either where the depth to ground water is less than 6 metres or there was no available data. This layer is indicative only, and should not be used at scales less than 1:150,000.

Description: The Coastal Confined Gravel Aquifer System is a relatively narrow band of confined gravel aquifers, situated near the coast between the Ashley and Rakaia rivers, bounded by the coastal marine area, Banks Peninsula, and on the western side by the line where sediments in the overlying confining layer are three metres thick. The aquifer system consists of at least five permeable gravel layers containing water (aquifer), separated by relatively impermeable layers of sediments (confining layers). Recognisable surface features have been used to approximate the natural boundary because the latter is not obvious at the ground surface.

Description: Gives the average height of ground water above sea level. This layer was created from a combination of shallow and deep aquifer ground water levels derived from averages of all available data in 2003 (approximately 20 years).
