The groundwater assessment component of the project has provided baseline knowledge on aquifer parameters essential to the planning of any horticultural development. An analysis was undertaken to produce a map delineating the level of groundwater resource risk associated with development. The study has been divided into four levels of risk (Low, Minor, Moderate or High), taking into consideration the risk criteria of electrical conductivity, aquifer thickness and depth below surface to productive aquifer.Links to download reports, maps and spatial datasets are noted in the Development Opportunities website. https://depws.nt.gov.au/DevelopmentOpportunities You are licensed to use the DEPWS geospatial products on terms and conditions set out in: Creative Commons Attribution 4.0 International Public License (CC BY 4.0) at: https://creativecommons.org/licenses/by/4.0/legalcode If you do not agree to the terms and conditions you must not use the geospatial products.

Through linear interpolation between these data points, contour lines were drawn for each risk criteria producing three maps. The three risk criteria maps were then overlaid to determine the extent of each of the four risk classes (Low, Minor, Moderate or High).
