Cardno expert demonstrates innovative remediation approaches

Danny McDonald, Senior Associate Environmental Geoscientist, presented on Assessing the Benefits of Air Sparging on Hydrocarbon Natural Source Zone Depletion Rate by Measuring Soil Gas Flux at the 2016 EcoForum Conference & Exhibition, October 25 – 28 in Fremantle, Western Australia.

Danny’s presentation assessed the benefits of air sparging (AS) on the natural source zone depletion (NSZD) rate of hydrocarbons in the vadose zone, which dominates degradation as compared to the active groundwater remediation at the site. Results from this study concluded that AS operation can enhance the rate of site remediation by increasing the NSZD rate. The presentation was part of a session track that was focused on reducing unexpected finds through diverse approaches in order to save money on your project.

The EcoForum is a broad-based environment conference that concentrates on contaminated land assessment, management and remediation, climate change, water, waste and communication. It provides environmental industry leaders to connect and learn from an array of track sessions focused on particular environmental concerns.

Danny McDonald has over 12 years’ experience in the field of environmental science backed with an outstanding resume of projects he has worked on throughout Australia, New Zealand, Papua New Guinea and Africa. His diverse experience across a range of specialty areas include acid sulfate soil assessments, investigation and remediation of algae contaminated water, geochemical investigations and contaminated land remediation. Danny is currently leading a program to assess and remediate over 50 historic fuel sites for a major oil company. A large part of this work is looking at risk based strategies and innovative remediation approaches to reduce the project cost.
