Andrew Rolfe

Before moving to Germany, Andrew Rolfe was a project manager working in our Sydney office for 15 years, working on major site remediation projects including management of the remediation planning works at the Barangaroo development project in Sydney, which involved the remediation of the former Millers Point gasworks site. In 2000, Andrew moved to Germany. He recently used his remediation experience to conduct a PFAS groundwater treatment trial at a German military site to assess the highest-performing and most cost-effective remediation solution to mitigate the offsite migration of PFAS impacted groundwater. Based on these studies, we subsequently prepare the remedial design for the groundwater remediation project - one of the first such projects in Germany. The groundwater extraction and treatment works will start later this year. The project also included a soil stabilization trial which assessed different adsorbents (including biochar) to stabilize PFAS-impacted soils. Because biochar is a waste by-product, it is a sustainable product and generates carbon credits. Andrew continues to work with the German biochar manufacturer to trial other types of biochar.
