Abstract
The Upper King River Managed Aquifer Recharge (MAR) investigation (the project) comprises part of a technical pre-feasibility study to determine the possibility of implementing a MAR scheme in the Katherine region of the Northern Territory. The project has been staged according to the Australian MAR Guidelines (the Guidelines) risk assessment framework for MAR scheme development (NRMMC, EPHC & NHMRC, 2009). Stage 1 of the project was completed in November 2022 and comprised an entry level risk assessment as well as recommended studies for the Stage 2 scope of works (Page et al., 2022). The drilling investigation has been completed as part of the Stage 2. The purpose of the drilling investigation is to assist in determining the suitability of the Tindall Limestone Aquifer (TLA) as a target storage reservoir for source water from the upper King River. The investigation aims to obtain information about the project site’s stratigraphy, aquifer hydraulic parameters, water quality, and river-aquifer connectivity. Activities completed for the investigation include drilling and construction of site investigation bores, borehole geophysical data collection, geochemical analysis of core samples to characterise sediment geochemistry and mineralogy, and water quality sampling.,
