The site is a former oil refinery and the same stringent fire precautions remain in place, this necessitated the use of flame and heat resistant overalls in addition to the usual ppe.
The purpose of this testing is to provide information for decision making in relation to retention or removal of excavation arising or any other spoil from site. We supervised and monitored a total of six trail pits mechanically excavated across the site. Trial pits were taken down to a depth of up to 1.50m.
A total of twelve near surface samples were collected from several locations across the site at depths of up to 1.50m. The soil was monitored on site with a photo-ionisation detector (PID) to identify any elevated levels of volatile compounds and assist in sample selection.
