Abstract:
Chemical assessment data for selected heavy metals determined for the abandoned waste disposal site at Thala Valley, Casey Station, over two seasons (pre- and during cleanup).
2002-03 summer: assessment of site, method testing
* samples TV001 to TV073
* spatial data determined using electronic theodolite
* total metals by XRF (mg/kg dry soil)
* leachable
... metals by TCLP/flame-AAS (mg/L extract) - independent analysis of leachates by ICP-MS (CSL)
* total metals data for Thala Valley tip fines standard (mg/kg dry soil) - ICP-MS of total digest and XRF (UTas SES-CODES), ICP-OES of aqua regia digest (DPIWE AST) 2003-04 summer: site assessment (limited), site validation after remediation, classification of excavated waste for disposal
* site samples (TVS001 to TVS038)
* spatial data determined using theodolite
* waste container samples for excavated waste (TVC****)
* total metals by XRF (mg/kg dry soil) - independent analysis of sample sub-set: ICP-OES of aqua regia digests (mg/kg)
* leachable metals by TCLP/flame-AAS (mg/L extract) - independent analysis by ICP-OES of sub-set of leachates, mg/L (DPIWE-AST) - independent TCLP/ICP-OES of sub-set of soil samples, mg/L (DPIWE-AST)
