Our multi-level approach for environmental forensics
The approach we provide for environmental forensics is broken down into the following tiers:
Tier 1: Identifying the contaminant
We start by identifying the type of contaminant present in environmental samples, laying the foundation for our investigation. We use standard and specialised methods to identify contaminants like petroleum hydrocarbons, PAHs, PCBs, metals, and chlorinated solvents.
Tier 2: Targeting specific compounds
In this phase, we pinpoint signature compounds unique to the contamination identified in Tier 1.
We employ techniques like gas chromatography coupled with mass spectrometry to analyse specific compound families, helping us determine similarities to source materials and the degree of weathering or biodegradation.
Tier 3: Data visualisation and analysis
Building on evidence from Tiers 1 and 2, we visualise data using techniques like chemical component histograms and compound ratio analysis spider plots. These visualisations help us translate complex environmental information into actionable insights, aiding in assigning responsibility for contamination incidents.
Successful environmental forensics requires an understanding of contaminant fate and transport, as well as proficiency in forensic tools and techniques. By combining scientific expertise with innovative methodologies, we strive to uncover environmental issues and promote sustainable practices.
