Abstract

A remediation program was designed and implemented at a site in southeastern Australia that had become contaminated with nonvolatile, n-alkane total petroleum hydrocarbons (TPH). The remediation was conducted in two stages. The excavation, validation and reinstatement of two contaminated areas on the site was first conducted, followed by development of a composting treatment process. The total volume of contaminated soil (i.e., TPH concentration> 1000 mg/kg C-10-C-36) was similar to 4300 m(3) with a concentration of 3100 +/- 1270 mg/kg. The soil was stockpiled into four windrows, on a compacted, bunded clay base. Approximately 35% (v/v) of raw materials (green treewaste, cow manure, gypsum, and nutrients) were added to initiate composting. The piles were kept moist during the summer months, but no other maintenance was conducted. Once the composting process was initiated, the windrowswere sampled at 2 and 6 months. After 6 months treatment, the average TPH concentration (C-10-C-36) was 730 mg/kg (with a 95% Cl of 1020 mg/kg), which met the relevant clean fill criteria applicable to the site. There were no other contaminants of significance in the treated soil compost and it posed no unacceptable risk to human health or the environment, allowing it to be used as fill at the site.
