Wentworth Point Contaminated Site


Our team has won a job to work in conjunction with EEIS Contracting on a contaminated site in Wentworth Point, NSW to prepare the site for future development use. EESI are currently undertaking remediation of the petroleum hydrocarbon impacted soil and groundwater likely caused by the operation of an old underground petroleum storage system. This includes removing remaining assets along with the excavation of contaminated material impacted areas to a depth of 3 metres.

We will be examining and determining a digital terrain model of the site before and after the contaminated soils have been excavated, to determine the accurate volume of soil removed and remediated. This will involve setting up survey controls throughout the site and assessing the site once hardstand, concrete and bitumen areas have been removed. The project also comprises using a Sokkia robotic total station, Palm hardware and preparing digital terrain models and will be performed over a period of up to 8 months after which the cleaned soil will be returned to the site.
