Abstract summary:
Introduction:
In the 'Screening Level Assessment of BHP Coalwash and Basic Oxygen Steelmaking and Blast Furnace Slags' undertaken by Sinclair Knight Merz it was identified that for coal wash refuse there was a significant lack of suitable data available and that consequently no assessment could be made for various trace elements of interest.
The aim of this report is therefore to provide the missing data gaps identified by SKM. This is being achieved by analysing the various blends of coalwash refuse that can be emplaced at Wongawilli. It will also allow characterisation of coalwash under the Waste Management Act Guidelines.
The analysis undertaken included determinatino of specific elemental concentrations and Toxicity Characteristics Leaching Procedure (TCLP) to determine the quality of leachate which can be generated under various conditions, with particular emphasis on metallic elements, various organics and PAH's.
