Fick, Oliver (2014) Remediation Action Plan: BP Junction Auto's corner Durlacher Street and Waldeck Street Geraldton, Western Australia. Internship Report, Murdoch University.

Abstract

BP Australia Limited (BP) leased Lots 33 and 34 located at the corner of Durlacher and Waldeck Street in Geraldton, Western Australia from August 1957 to February 2003. The Site, known at “Junction Auto’s” was sold to Clarisse Holdings (Sovereign Petroleum) in February 2003, with BP later acquiring Sovereign Petroleum and retaining liability to remediate the Site to comply with commercial/industrial use screening criteria.

In April 2007, the Site was closed for decommissioning and remedial works, inclusive of the removal of petroleum infrastructure, excavation to a maximum depth of 6.5m BGL, removal of impacted soil, backfilling of clean soil and validation soil samples were completed. The validation samples collected, with the exception of two, were all ‘non detect’.

Since decommissioning, the Site has been monitored both on-site and off-site under the bi-annual groundwater monitoring program. Four wells along the North-Western side of the Site continue to yield high TPH/BTEX levels, sheens and strong odours.

After reviewing all available historical soil and groundwater data, the source of contamination was found to be along the North-Western border.

BP intends to sell the Site for residential development and as such the Site must be remediated. Modelling using BIOSCREEN indicates that contamination above guidelines will remain after 10 years if there is no source removal.

A number of techniques were examined for remediating the residual contamination; in-situ chemical oxidation (ISCO) was scored the highest through a screening matrix.

It is recommended that 1680kg Klozur® CR is required to remove the contamination source and according to the BIOSCREEN modelling, after 5 years the residual plume will be degraded.This project investigation of the torque speed curve was completed and provided an insight into the torque speed characteristics of the Lab-Volt machines. It provides a basis for further experimentation and comparison with other methods available for determining the machine characteristics.
