DPI groundwater database

This document presents an in-depth analysis of groundwater bore characteristics, focusing on Bore 1 with a diameter of 125mm and specific aquifer properties. Key parameters include bore maintenance case height (0.29m), screen intervals (9m to 12m), and various lithological data. Groundwater levels are examined, showing significant measurement points from August 1986, with depths indicating both saturated and partly saturated aquifer conditions. The effects of casing and screen construction on water flow are also discussed, providing a comprehensive overview for groundwater assessments.
