Display Field: AquiferName
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: This layer contains locations where aquifer tests and pump tests have been conducted in Otago. The layer is based on the ORC archives dating back to catchment board days to recent aquifer tests that have been undertaken by applicants or their consultant to obtain groundwater take consents. The list is incomplete, and we are endeavouring to make this list as complete as possible soon which will also include assessments of the tests results for accuracy, applicability of the results, analysis method used and quality of the test setup.Field NameUnitDescriptionIDInternal Test identifierWellNumberThe ORC well number pumped well.
