TOPIC: Sediments (not soil) and why you need to know more than just the trigger level
PRESENTERS: Dr Sarah Eccleshall, Carmen Yi and Jacqui Hallchurch, GHD
TIME: 2.00pm webinar via MS Teams
- Have you ever found yourself staring at the guidelines and wondering what to do with sediment data for your site?
- Have you ever found yourself trying to use the sediment guidelines but then realised you don’t have Total Organic Carbon (TOC) data?
- Have you ever wondered why we even bother to normalise organic sediment data against TOC?
- Are you interested in knowing more about sediment assessment (and how that is different to soil assessment), and some real life projects on sediment investigation and management?
If so, then this presentation is for you.
We will cover the key framework around sediments and things to consider as part of your investigation.
Dr Sarah Eccleshall
Sarah has been a member of the contamination and environmental management team at GHD in Sydney since 2018. Graduating with a BSc(hons) in Earth Sciences from University of Wales, Aberystwyth she then went on to pursue a MSc in Quaternary Geology at Stockholm University focusing on sediment deposition as a chronometer for fluctuations in glacial extent in Arctic Norway. Sarah then completed a PhD in fluvial sedimentology and geomorphology at Wollongong University, establishing the timing of climatic changes using fluvial sediment records as an indicator of hydrological variability in arid Australia. Sarah has worked in a wide range of sedimentary environments and is particularly interested in how the physical properties of sediment effect its mobility and contamination status. During her time at GHD Sarah has been heavily involved in a number of projects revolving around sediment contamination in the marine environment focusing on the assessing of contamination and the associated risks in regards to dredging activities.
Carmen is a senior environmental engineer at GHD with seven years’ consulting experience. Carmen has mostly worked on contamination assessment and management in due diligence, asset management and multi-disciplinary development projects ranging from inland to offshore locations. Carmen has a background in civil and geotechnical engineering and she has a particular interest in developing practical contamination management solutions based on scientific evidence to support clients and communities in realising environmental benefits.
Jacqui is a Technical Director and Certified Environmental Practitioner with 18 years’ experience in environmental site assessments. Jacqui’s passion for all things marine, and her particular interest in sediments, started whilst working on a research boat in a Scottish Loch during her undergraduate degree in 1999. Quickly realising there would be warmer places in the world to do research, Jacqui joined an organisation and field scientists responsible for leading reef based monitoring in Indo Pacific and Caribbean regions, again focusing on sediment deposition in marine environments. Since joining GHD in 2005, Jacqui has been involved with the assessment and remediation of contaminated sediments including the role of technical project manager for the delivery of the Hunter River Remediation Project and other programs of works in multiple operational port and harbour environments across NSW, QLD and NT.
