Geosyntec Practitioners Contribute to Groundwater Fate and Transport Symposium

Scott Ambridge, PEng; Lange Jorstad, PhD; Claire Miller; and Daniel Hodges, CEnvP, will contribute to the Groundwater Fate and Transport Symposium on February 25 and 26, 2026, in Sydney, Australia.

Scott is a Senior Professional Engineer based in Ontario with more than 20 years of experience focused on investigating, assessing, and remediating contaminated sites in Canada, the United States, Australia, and New Zealand.

Lange is a Senior Principal Contaminant Hydrogeologist based in Australia with more than 25 years of experience in the design, management, and delivery of contaminated land assessment and remediation services and related corporate advisory services in Australia, the Asia Pacific region, and the United States.

Claire is a Senior Hydrogeologist based in Australia with more than 20 years of experience managing complex fieldwork, data, projects, and technical reports according to national and state standards. She supports clients in the oil and gas, infrastructure, manufacturing, energy, waste, and mining sectors.

Daniel is a Principal Engineer based in Australia with more than 15 years of experience focused on environmental site assessments and contaminant hydrogeology. Daniel provides technical leadership for complex contaminated sites and offers demonstrated site closure experience.

The symposium, hosted by the Australasian Land and Groundwater Association (ALGA), centers on groundwater mass flux concepts to enhance contaminated site assessment and decision-making. ALGA provides a platform for professionals who work to protect and manage land and groundwater in Australasia.
