Key Staff

Alex Savaglia


With over 12 years’ experience in mining and contaminated land investigation and remediation within SA, Victoria and NSW, Alex has worked for over 10 years as a contaminated land consultant and several years as an exploration geologist.

Alex has managed large-scale site investigation and remediation at the Former Adelaide Refinery Project in Lonsdale, SA which included desktop history review, intrusive investigations and groundwater studies on the nature and extent of contaminants of potential.

In 2018 Alex was tasked with developing an innovative investigation methodology for a highly odourous and noxious exotic chemical (ethyl mercaptan). The investigation methodology Alex developed won the 2020 ALGA excellence award for the best scoping of an investigation.

Alex has also managed remediation of the former Port Augusta Power Station and Leigh Creek Coal Mine following their closure in 2017. The remediation for both sites was largely comprised of bioremediation of soil on-site for beneficial use, in-situ chemical dosing of an oxidant to groundwater, and infrastructure removal oversight including UST farms and associated fuel transport lines (some kilometres long), and various supporting infrastructure. This project also won an ALGA excellence award for the best remediation project <$1m in 2019.
