Hydrocarbon (Fuel/ Oil) Testing and Assessment
In common with all contamination risk assessments, the assessment of TPH and PAH contamination starts with the desk study, which might include a petroleum storage licence search, to identify whether or not there are any records of underground fuel storage on-site.
Volatile organic compounds (VOCs) can be monitored with a photo-ionisation detector (PID).
The vapour inhalation can be as important as the ingestion pathways in consideration of human health risks. The physio-chemical properties, including half-life and soil-partition coefficient, need to be considered in controlled waters risk assessments.
Remedial measures might include source removal/ treatment and/ or barriers (capping, membranes etc.).
