Multivariate statistical analyses of groundwater and surface water chemistry data for Isa GBA region

Abstract

This dataset is a combined Excel spreadsheet dataset that integrates all available groundwater and surface water chemistry historical records. It includes field quality parameters, methane concentrations and major and minor ion concentrations. It is based on the following data sources: GA compiled hydrochemistry datasets: Surface water data from the Queensland water monitoring information portal (https://water-monitoring.information.qld.gov.au/), accessed and downloaded in January 2019; Data from EHS Support (2014) Water baseline assessment (ATP1087) prepared for Armour Energy.

History

A hierarchical cluster analysis was conducted on groundwater and surface water datasets from the Isa GBA region. For this purpose, nine variables (Ca, Mg, Na, K, HCO3, Cl, SO4, electrical conductivity and pH) which were measured across most hydrochemical records were selected. Prior to the multivariate statistical analysis, all variables except for pH were log-transformed to ensure that each variable more closely follows a normal distribution. The multivariate statistical technique is described in more details by Raiber et al. (2012) and Raiber et al. (2016).
