AWN Consulting undertook a pre-acquisition due diligence site investigation on a former petrol station in West Dublin. Consequently, AWN Consulting was included in a framework for Renault in Ireland.

Areas of potential concern (APCs) were identified using historical ordnance survey maps and a review of planning conditions for the former petrol station. The site investigation targeted the areas around underground fuel tanks and an overground kerosene tank; the following works were carried out:

• Characterisation of the soil around the APCs identified in the environmental due diligence;
• Assessment of the nature and degree of any hydrocarbon contamination of the soil in the vicinity of known potential sources of contamination;
• Assessment of any shallow groundwater encountered, and;
• Interpretation of the analytical results with respect to the identified environmental receptors at the site.

Based on the information obtained from the environmental due diligence and the site investigation, a preliminary Conceptual Site Model (CSM) was developed and a qualitative risk assessment undertaken to consider the potential contaminative and environmental risks associated with the current land condition at the site.
