Hydrocarbon (Fuel/ Oil) Testing and Assessment

Total petroleum hydrocarbon (TPH) and polyaromatic hydrocarbon (PAH) chemicals, derived from fuels/ oils, are key contaminants of concern in both human health and controlled waters risk assessments.

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.).
